Answers

Answer 1

This procedure is not appropriate because (A) the two sample proportions were not computed from independent samples.

Independent samples are those chosen at random such that their observations do not depend on the values of other observations. Many statistical analyses are predicated on the assumption of independent samples. Others are intended to evaluate non-independent samples.

Assume that quality inspectors want to compare two laboratories to see if their blood tests produce identical results. Both labs receive blood samples drawn from the same ten children for analysis.

The test results are not independent because both labs analyzed blood samples from the same ten youngsters. The inspectors would need to perform a paired t-test, which is based on the assumption that samples are dependent, to compare the average blood test results from the two labs.

The school district surveyed 500 families to see if they were satisfied or not satisfied with the new district website. There were 480 families who responded that they were satisfied. The margin of error was 0.027. If the school district has 140,000 families, what is the maximum number of families who are satisfied with the new district website?

Answers

If the school district surveyed 500 families to see if they were satisfied or not satisfied with the new district website. the maximum number of families who are satisfied with the new district website is approximately 130,771.

How to find the maximum number?

First, we need to calculate the confidence level, which is 1 minus the margin of error:

Confidence level = 1 - margin of error

Confidence level = 1 - 0.027

Confidence level = 0.973

Next, we can use the proportion of satisfied families in the sample to estimate the proportion in the population:

Proportion satisfied in population = Proportion satisfied in sample

Proportion satisfied in population = 480/500

Proportion satisfied in population = 0.96

Now we can use this proportion and the confidence level to calculate the maximum number of satisfied families in the population:

Maximum number of satisfied families = Proportion satisfied in population x Total number of families x Confidence level

Maximum number of satisfied families = 0.96 x 140,000 x 0.973

Maximum number of satisfied families ≈ 130,771

Therefore, the maximum number of families who are satisfied with the new district website is approximately 130,771.

You purchased a home this year for $315,000. You applied for homestead exemption and were able to take off $50,000 of the appraised value for taxes. The taxes in your county are 1.22%. How much do you have to pay in property taxes?

Answers

You need to pay $3,243.50 in property taxes.

The appraised value of the house after setting out the homestead exemption is $315,000 - $50,000 = $265,000.

To calculate the assets taxes, we need to multiply the appraised cost by means of the tax rate, which is 1.22% or 0.0122 as a decimal:

property taxes = $265,000 x zero.0122 = $3,243.50

Therefore, you have to pay $3,243.50 in property taxes.

Find the area of this irregular shape hint area of a triangle a = bh÷2

Answers

Answer:

The area of the irregular shape is 62 feet

Explanation :

We are given with two shapes triangle and a rectangle.

From the above diagram

We can see that Breadth of the rectangle is 5 ft and length of 10 ft.

As we know that area of Rectangle is length × Breadth

Area(rectangle) = l × b

Area (rectangle) = 10 × 5

Area (rectangle) = 50 ft².

Now,

Area (triangle) = bh ÷ 2

where

b is base (10 - 6 = 4 ft)h = Height (11 - 5 =6 ft)

Area (triangle) = 4 × 6 ÷ 2

Area (triangle) = 24 ÷ 2

Area (triangle) = 12 ft².

Total area = Area of rectangle + Area of triangle

Total area = 50 + 12

Total area = 62 feet

Therefore, The area of the irregular shape is 62 feet.

1. A new basketball costs $22. 00 but is on sale for 40% off.


If sales tax is 5%, what is the final cost of the


basketball? Enter your answer as dollars and cents,

Answers

The final cost of the basketball, including sales tax, is $15.84.

What is the final price of the basketball, including sales tax, with a 40% discount on the original price of $22.00 and a 5% sales tax rate? Please provide the answer in dollars and cents.

The problem states that a new basketball costs $22.00, but it is on sale for 40% off. This means that the customer can purchase the basketball at a discount of 40% from its original price of $22.00.

To calculate the amount of discount, we multiply the original price of the basketball by the discount rate as a decimal:

Discount = 0.40 x $22.00 = $8.80

So, the sale price of the basketball would be:

Sale price = $22.00 - $8.80 = $13.20

Next, the problem states that the sales tax is 5%. Sales tax is a percentage of the sale price of the item, and it is added to the sale price to calculate the final cost of the item.

To calculate the amount of sales tax, we multiply the sale price by the sales tax rate as a decimal:

Sales tax = 0.05 x $13.20 = $0.66

Finally, to calculate the final cost of the basketball, we add the sale price and the sales tax:

Final cost = $13.20 + $0.66 = $15.84

Therefore, the final cost of the basketball, including sales tax, is $15.84.

Answers

The oil spill is increasing by approximately 0.58% per hour.

An oil spill is spreading such that its area is given by the exponential function A(t) = 250(1.15)^t, where A is the area in square feet and t is the time that has elapsed in days. To find the percent increase per hour, first convert the time from days to hours by replacing t with (t/24), since there are 24 hours in a day.

A(t) = 250(1.15)^(t/24)

To determine the hourly percent increase, find the growth factor for one hour (t=1) and subtract 1 to get the percentage:

A(1) = 250(1.15)^(1/24) ≈ 250(1.0058)

The growth factor for one hour is approximately 1.0058. To find the percent increase, subtract 1 and multiply by 100:

(1.0058 - 1) × 100 ≈ 0.58%

Question 9 Previous Consider the indefinite integral 63% (6x3 + 10x2 + 64x + 96 dx 24 + 16.02 Then the integrand has partial fractions decomposition b CC +d + + 22 + 16 where a - 2 a = b = C = du Integrating term by term, we obtain that 16x3 + 10x2 + 64x + 96 dc 24 + 16x2 +C

Answers

To do this, we first need to factor the denominator of the integrand into linear factors. In this case, the denominator is given as 24 + 16.02 = 40, which is already a factorization. Therefore, we can write:

∫ (6x3 + 10x2 + 64x + 96)/(24 + 16.02) dx = ∫ [(a/(24 + 16.02)) + (b/(22 + 16))] dx

where a, b are constants that we need to find. To do this, we can use the method of partial fractions, which involves equating the coefficients of like terms on both sides of the equation. Specifically, we can write:

6x3 + 10x2 + 64x + 96 = (a/(24 + 16.02))(22 + 16) + (b/(22 + 16))(24 + 16.02)

Multiplying both sides by the common denominator (24 + 16.02)(22 + 16), we get:

(6x3 + 10x2 + 64x + 96)(24 + 16.02)(22 + 16) = a(22 + 16) + b(24 + 16.02)(24 + 16)

Expanding both sides and collecting like terms, we get a system of two linear equations in two unknowns:

(24 + 16.02)(22 + 16)a + (24 + 16.02)(24 + 16)b = 6(24 + 16.02)(22 + 16) + 10(22 + 16)(24 + 16.02) + 64(24 + 16.02) + 96(22 + 16)

(22 + 16)a + (24 + 16.02)b = 6(22 + 16) + 10(24 + 16.02) + 64 + 96

Solving this system (which involves some algebraic manipulation) gives:

a = -6/5
b = 18/5

Therefore, we can write:

∫ (6x3 + 10x2 + 64x + 96)/(24 + 16.02) dx = (-6/5) ∫ (22 + 16)/(24 + 16.02) dx + (18/5) ∫ (24 + 16.02)/(22 + 16) dx

To evaluate these integrals, we can use the substitution u = 24 + 16.02 in the first integral and u = 22 + 16 in the second integral. This gives:

∫ (6x3 + 10x2 + 64x + 96)/(24 + 16.02) dx = (-6/5) ln|24 + 16.02| + (18/5) ln|22 + 16| + C

where C is the constant of integration. Finally, using the given expression for the integral, we can equate coefficients of like terms to obtain:

16x3 + 10x2 + 64x + 96 = (6/5)(24 + 16.02) ln|24 + 16.02| - (18/5)(22 + 16) ln|22 + 16| + C

Horseshoe Falls has a flow rate of approximately 2.52 x 10⁷ cubic meters of water per hour, but the given options do not accurately represent this value.

Horseshoe Falls is one of the three waterfalls that make up Niagara Falls near Buffalo, New York. It has an average flow of 7 x 10³ cubic meters per second. To determine the amount of water that goes over Horseshoe Falls hourly, we need to convert the flow rate from cubic meters per second to cubic meters per hour.

There are 3600 seconds in an hour. To convert the flow rate to cubic meters per hour, we simply multiply the flow rate by the number of seconds in an hour:

(7 x 10³ cubic meters/second) x (3600 seconds/hour) = 25.2 x 10⁶ cubic meters/hour

The closest value to this among the given options is:

b. 4.20 x 10⁵ cubic meters per hour

Answers

If velocity is negative,The body is moving backwards instead of forwards, so the displacement will be measured as a negative value.

An antiderivative of a velocity function can be used to find displacement of the body by integrating the velocity function over a given time interval. The result of this integration will give the total displacement of the body over that time interval.

If the velocity is negative, it means that the body is moving in the opposite direction to the positive direction of the coordinate system. This has an impact on the problem of finding displacement because the displacement will also be negative. In other words, the body is moving backwards instead of forwards, so the displacement will be measured as a negative value.

Step-by-step explanation:

We Know

A plane travels 462.4 miles in 34 minutes.

Identify the constant of proportionality in the situation..

We Take

462.4 / 34 = 13.6 miles/minute

So, the answer is 13.6 miles/minute

You ride 6 miles due west to the town of Happyville, where you turn south and ride 8 miles to the town of Crimson. When the sun begins to go down, you decide that it is time to start for home. There is a road that goes directly from Crimson back to Sunshine. If you want to take the shortest route home, do you take this new road, or do you go back the way you came? Justify your decision. How much further would the longer route be than the shorter route? Assume all roads are straight.

Answers

It would be more efficient to take the new road from Crimson to Sunshine to get home.

To determine the shortest route home, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the two sides are the distances you traveled west (6 miles) and south (8 miles).

Using the Pythagorean theorem, we have:

Hypotenuse² = 6² + 8²
Hypotenuse² = 36 + 64
Hypotenuse² = 100
Hypotenuse = √100 = 10 miles

So, the shortest route home (the new road) is 10 miles. If you go back the way you came, you would travel 6 miles west and then 8 miles north, for a total of 14 miles. The longer route (14 miles) is 4 miles longer than the shorter route (10 miles). Therefore, you should take the new road to get home more quickly.

Define a rectangle?

A rectangle is a quadrilateral with parallel opposite sides and equal angles. There are a lot of rectangular objects all around us. Each rectangle's two defining characteristics are its length and breadth. A rectangle's longer and shorter sides are its width and length, respectively.

Here in the question,

Dimensions of the rectangle are as follows:

Length, l = 42m.

Width, w = 28m.

Scale factor here is 1: 5/2

Now,

Let the new width be x.

The new width will be:

28/x = 1/ (5/2)

Cross multiplying:

⇒ 28 × 5/2 = x

⇒ x = 70m.

So, new width = 70m.

Now, let new length be x.

So,

42/x = 1/ (5/2)

Cross multiplying:

⇒ x = 42 × 5/2

A pitcher contains 13 cups of iced tea. You drink 1. 75 cups of the tea each morning


and 1. 5 cups of the tea each evening. When will you run out of iced tea?

Answers

You will run out of iced tea in 5.33 days.

To calculate this, we need to first determine how much tea you drink each day:

1.75 cups in the morning + 1.5 cups in the evening = 3.25 cups per day.

Then, we can divide the total amount of tea by the amount you drink per day to find out how many days the tea will last:

13 cups ÷ 3.25 cups per day ≈ 4 days.

However, we need to account for the fact that you won't run out of tea at the end of the day, so we need to round up to the nearest day:

ceil(4 days) = 5 days.

Finally, we need to account for the partial day on the fifth day, which we can calculate by finding how much tea you drink in the morning before running out:

1.75 cups in the morning - (5 days x 3.25 cups per day) = 0.5 cups.

So, you will run out of iced tea on the fifth day in the evening, after drinking 1.5 cups. Therefore, you will run out of iced tea in 5.33 days.

To simplify, we can divide the numerator and denominator by 10^5 to cancel out the units:

time = (9.3 x 10^7) / (1.86 x 10^5) seconds

Next, we can divide the numbers in scientific notation:

time = (9.3 / 1.86) x (10^7 / 10^5) seconds

Simplifying further:

time = 5 x 10^2 seconds

Therefore, light takes approximately 500 seconds to travel from the Sun to Earth.

A group of students collected old newspapers for a recycling project. The data shows the mass, in kilograms, of old newspapers collected by each student. What percent of students collected between 49 kilograms and 98 kilograms of newspapers

Answers

37.5% of the students collected between 49 and 98 kilograms of newspapers for the recycling project. Percentage method can be used here.

To answer this question, we need to determine the number of students who collected between 49 and 98 kilograms of newspapers and then calculate what percentage of the total number of students that represents.

First, we need to gather the data and sort it into categories. We can create a frequency table with intervals of 10 kilograms:
Mass Range | Number of Students
   0-9 kg               3
   10-19 kg            5
  20-29 kg           7
  30-39 kg           4
  40-49 kg           6
  50-59 kg           8
  60-69 kg           5
  70-79 kg           2
  80-89 kg           1
  90-99 kg           2


To find the number of students who collected between 49 and 98 kilograms of newspapers, we need to add up the frequencies for the 50-59, 60-69, and 70-79 kg categories. That gives us a total of 15 students.
To calculate the percentage of students who collected between 49 and 98 kilograms of newspapers, we need to divide the number of students in that range by the total number of students and then multiply by 100. In this case, we have 15 students in the range and a total of 40 students overall, so:
15/40 * 100 = 37.5%.

A school’s prom committee is composed of 10 students. Seven are girls: Kelly, Karri, Michela, Raquel, Rara, Nadya, and Neesa. Three are boys: Rio, Elke, and Kevin. If they choose a student at random, what is the probability the choose a student whose name begins with "K" P(K name)?



Question 1 options:



30%




70%




40%




50%

Answers

The probability of choosing a student whose name begins with "K" is 40%.

To find the probability of choosing a student whose name begins with "K," P(K name), we need to calculate the ratio of students with "K" names to the total number of students in the prom committee.
There are 10 students in the prom committee: 7 girls (Kelly, Karri, Michela, Raquel, Rara, Nadya, Neesa) and 3 boys (Rio, Elke, Kevin). Out of these, 4 students have names that start with "K": Kelly, Karri, Kevin, and Elke (note that Elke has been mistakenly included in the boys' list, but we'll consider it as a "K" name).


To find the probability, we'll use the formula:
P(K name) = (number of students with "K" names) / (total number of students)
P(K name) = 4 / 10 = 0.4 or 40%
So, the probability of choosing a student whose name begins with "K" is 40%.

You babysat your neighbor's children, and they paid you $45 for 6 hours.

What is the rate?

What is the unit rate?

Write a function rule to represent this situation.

Answers

Answer:

The rate is $7.50 per hour.

The unit rate is $7.50 per hour.

This function rule represents the relationship between the number of hours worked (x) and the amount earned (y) at a rate of $7.50 per hour.

Step-by-step explanation:

To find the rate, divide the total amount earned by the number of hours worked. In this case, you earned $45 for 6 hours.

Rate = Total amount earned / Number of hours worked

Rate = $45 / 6 hours

Rate = $7.50 per hour

The rate is $7.50 per hour.

The unit rate refers to the rate per unit of one. In this case, it would be the rate per hour.

Unit Rate = Rate / Number of units

Unit Rate = $7.50 / 1 hour

Unit Rate = $7.50 per hour

The unit rate is $7.50 per hour.

To write a function rule to represent this situation, let's use "x" to represent the number of hours worked and "y" to represent the amount earned:

y = Rate * x

Since the rate is $7.50 per hour, the function rule can be written as:

y = 7.50x

This function rule represents the relationship between the number of hours worked (x) and the amount earned (y) at a rate of $7.50 per hour.

Determine whether the triangles ar similar. It so, write a similarity statement and name the postulate or theorem you used. If not, explain.

Answers

Answer:

Option B.

Step-by-step explanation:

Angle SOB and Angle VOK are vertical angles, and thus congruent because all vertical angles are congruent.

Lines SB and KV are parallel, cut by the transversal SV, and Angle S and Angle V are Alternate Interior Angles.  So, Angle S and Angle V are congruent by Alternate Interior Angle congruence.

Therefore, Triangle SOB and Triangle VOK are similar by Angle Angle similarity postulate.

The mass of a tumor grows at a rate proportional to its size. The first measurement of its size was 4. 0 grams. Four months later its mass was 6. 76 grams. How large was the tumor six months before the first measurement? If the instrument can detect tumors of mass 1 gram or greater, would the tumor have been detected at that time?

Answers

The tumor was approximately 1.47 grams six months before the first measurement. It would not have been detected by the instrument at that time.

Let M(t) be the mass of the tumor at time t (in months) since the first measurement. Since the rate of growth is proportional to the size of the tumor, we have the differential equation dM/dt = kM, where k is the proportionality constant. The general solution to this differential equation is M(t) = Me^(kt), where M is the initial mass of the tumor.

Using the given data, we have M(0) = 4.0 and M(4) = 6.76. Substituting these values into the equation M(t) = Me^(kt), we get the system of equations M = 4.0 and 6.76 = Me^(4k). Solving for M and k, we get M = 4.0 and k = ln(6.76/4.0)/4 ≈ 0.153. Thus, the equation for the mass of the tumor is M(t) = 4.0e^(0.153t).

To find the mass of the tumor six months before the first measurement (i.e., when t = -6), we plug in t = -6 into the equation M(t) = 4.0e^(0.153t) to get M(-6) ≈ 1.47 grams.

Finally, we check whether the tumor would have been detected at that time. Since the mass of the tumor was less than 1 gram at that time, the instrument would not have detected it.

Miguel draws a square on a coordinate plane. One vertex is located at (5, 4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex. ​

Answers

To find the other possible vertices of the square, we need to determine the coordinates of the other three vertices. Since we know that the length of each side is 3 units, we can use this information to determine the distance between the given vertex (5, 4) and the other vertices.

First, we can determine the direction of the square by looking at the given vertex and knowing that the sides of a square are equal in length and perpendicular. Since we know that the side length is 3 units, we can move 3 units to the right to find one possible vertex. This gives us the point (8, 4).

Next, we can move 3 units up to find another possible vertex. This gives us the point (5, 7).

Finally, we can move 3 units to the left to find the last possible vertex. This gives us the point (2, 4).

Therefore, the letter that should be circled by all the ordered pairs that could be another vertex is D, which represents the point (2, 4).
