Ross Times, the student newspaper of Ross College, printed a "What do you think?" column feature asking: "Do you think that the college is doing enough to provide student parking?" Anyone could mail in a response or use the paper's Web site to respond. In all, 126 answers were received.




This is an example of:




(a) a voluntary response sample.



(b) a multistage sample.



(c) a simple random sample.



(d) a convenience sample.



(e) the placebo effect

Answers

Answer 1

The answer is (d) a convenience sample.

This is because the sample is not randomly selected from the population of all students at Ross College. Instead, it relies on individuals who are willing and available to respond to the question through the methods provided by the newspaper.

Therefore, the sample is more likely to be composed of individuals who feel strongly about the issue of student parking or who have had particularly positive or negative experiences with it, rather than being representative of the entire population of Ross College students.

In conclusion, the Ross Times student newspaper's feature column asking for opinions on the provision of student parking at Ross College represents a convenience sample of responses, and may not be representative of the entire population of Ross College students.

24 months at 6. 5% annual simple interest rate




30 months at 6. 00% annual simple interest rate

Answers

For a purchase of a new desktop computer for $1250, loan description that would result in the smallest amount of interest she would have to pay is 12 months at 6. 25% annual simple interest rate. Therefore, the correct option is option 1.

To determine which loan description results in the smallest amount of interest for Roxie, we'll calculate the interest for each option using the simple interest formula:

Interest = Principal × Rate × Time.

1. 12 months at 6.25% annual simple interest rate:

Interest = $1250 × 6.25% × (12/12)

Interest = $1250 × 0.0625 × 1

Interest = $78.13

2. 18 months at 6.75% annual simple interest rate:

Interest = $1250 × 6.75% × (18/12)

Interest = $1250 × 0.0675 × 1.5

Interest = $126.56

3. 24 months at 6.5% annual simple interest rate:

Interest = $1250 × 6.5% × (24/12)

Interest = $1250 × 0.065 × 2

Interest = $162.50

4. 30 months at 6.00% annual simple interest rate:

Interest = $1250 × 6.00% × (30/12)

Interest = $1250 × 0.06 × 2.5

Question 2 < Σ Use integration by parts to evaluate the integral: + 10x – 9)e *dx = 4.1 f(x²

The value of integral ∫(x^2+10x-9)e^-4x dx is  (-1/4)(x^2+10x-9)e^-4x - (1/8)(x+5)e^-4x - (1/32)e^-4x + C.

To evaluate the integral ∫(x^2+10x-9)e^-4x dx using integration by parts, we need to choose two functions to multiply together, one of which we differentiate and the other we integrate. A common choice is to let u = x^2+10x-9 and dv = e^-4x dx, which gives du = (2x+10) dx and v = (-1/4)e^-4x.

Using the formula for integration by parts, we have:

∫(x^2+10x-9)e^-4x dx = uv - ∫v du

= (-1/4)(x^2+10x-9)e^-4x - ∫(-1/4)(2x+10)e^-4x dx

= (-1/4)(x^2+10x-9)e^-4x + (1/2)∫(x+5)e^-4x dx.

Now we can use integration by substitution to evaluate the second integral on the right-hand side:

(1/2)∫(x+5)e^-4x dx = (-1/8)(x+5)e^-4x - (1/32)e^-4x + C,

where C is the constant of integration.

Substituting this back into our previous equation, we get:

∫(x^2+10x-9)e^-4x dx = (-1/4)(x^2+10x-9)e^-4x - (1/8)(x+5)e^-4x - (1/32)e^-4x + C.

The equation oe: y + 1 = -4/6(x + 5) represents a line perpendicular to line m.

The equation of line m is given as y + 2 = (3/2)(x + 4). To determine the equations that represent lines perpendicular to line m, we need to find the negative reciprocal of the slope of line m and use it as the slope in the perpendicular lines.

The slope of line m is (3/2), so the negative reciprocal is -2/3. We can eliminate options oa, oб, and of because they do not have a slope of -2/3.

Now, let's check the remaining options:

oc: y = (2/3)x + 4

This equation has a slope of 2/3, which is not the negative reciprocal of -2/3. Therefore, it is not perpendicular to line m.

od: y = (3/2)x + 4

This equation has the same slope as line m, which means it is not perpendicular to line m.

oe: y + 1 = (-4/6)(x + 5)

Simplifying the equation, we get y + 1 = (-2/3)(x + 5), which has a slope of -2/3. Therefore, this equation represents a line that is perpendicular to line m.

Answers

Kritim's percentage profit is 8.5%.

Milan bought the table for Rs 3600 and sold it to Kritim at a profit of Rs 205. Hence, Kritim paid Rs 3600 + Rs 205 = Rs 3805 for the table. Kritim then sold the table to Aayush for Rs 4968.

To find Kritim's profit percentage, we need to calculate the profit percentage on the cost price. The cost price for Kritim is Rs 3805, and the selling price is Rs 4968. Hence, the profit earned by Kritim is Rs 4968 - Rs 3805 = Rs 1163.

Profit percentage = (Profit / Cost price) x 100%

Profit percentage = (1163 / 3805) x 100%

Profit percentage = 0.3055 x 100%

The mean of a continuous uniform distribution is simply the average of the upper and lower limits of the interval on which the distribution is defined. true or false

Answers

True. In a continuous uniform distribution, all values within a specified interval are equally likely to occur. The mean or expected value of this distribution can be found by taking the average of the upper and lower limits of the interval.

This can be represented mathematically as (a+b)/2, where a and b are the lower and upper limits of the interval. For example, if we have a continuous uniform distribution on the interval [0,10], the mean value would be (0+10)/2 = 5.

This means that on average, we would expect a randomly selected value from this distribution to be around 5. It's important to note that the mean of a continuous uniform distribution is not affected by the shape or spread of the distribution, as all values have an equal chance of occurring.

Answers

The probability in the two fair dice problem is given as [tex]P(A|B) = 1/6[/tex].

How to calculate probability in the two fair dice problem?

To find [tex]P(A|B)[/tex], we first need to find [tex]P(B)[/tex], which is the probability that two dice are showing different faces.

The total number of possible outcomes when rolling two dice is [tex]6x6 = 36[/tex]. Out of these [tex]36[/tex] possible outcomes, there are [tex]6[/tex] outcomes where both dice show the same face (e.g., both dice show a 1). Therefore, there are [tex]36-6=30[/tex] outcomes where two dice show different faces.

Hence, P(B) = [tex]30/36 = 5/6[/tex].

Next, we need to find the probability of A and B occurring together, i.e., P(A and B).

The possible pairs of faces that add up to 10 are [tex](4,6), (6,4),[/tex] and [tex](5,5)[/tex]. Each of these pairs can occur in 2 ways (e.g., the pair [tex](4,6)[/tex] can occur as [tex](4,6) or (6,4))[/tex]. Therefore, there are 6 ways in total for the sum of two dice to be 10.

Out of these 6 outcomes, only one outcome (the pair (5,5)) violates condition B (i.e., both dice showing the same face). Therefore, there are [tex]6-1=5[/tex] outcomes where the sum of the two dice is 10 and the two dice show different faces.

Hence, P(A and B) [tex]= 5/36[/tex].

Using the formula for conditional probability, we can find P(A|B) as:

[tex]P(A|B) = P(A and B) / P(B) = (5/36) / (5/6) = 1/6.[/tex]

Therefore, [tex]P(A|B) = 1/6[/tex], which is the required probability.

Isaiah earns 6.5 points for each visit, so the total points he earns after x visits is 6.5x.

He also received 75 points just for signing up, so the total number of points he has is 75 + 6.5x.

To earn a free movie ticket, he needs at least 140 points, so we can write the inequality:

75 + 6.5x ≥ 140

To show that the series Σα) f(n)/2n^3 - 1 n converges regardless of the rule for f, we can use the Comparison Test. Let's choose a series that is easier to compare to, such as Σ(1/2n^3).



First, note that 0 ≤ f(n) ≤ 1 for all n, since f is a function that is not negative and bounded by 1. Thus, we have: 0 ≤ f(n)/2n^3 - 1 n ≤ 1/2n^3, Now, we can compare the given series to the series Σ(1/2n^3) using the Comparison Test. Since 0 ≤ f(n)/2n^3 - 1 n ≤ 1/2n^3 for all n, we know that: 0 ≤ Σα) f(n)/2n^3 - 1 n ≤ Σ(1/2n^3), The series Σ(1/2n^3) is a convergent p-series with p = 3 > 1, so by the Comparison Test, the given series Σα) f(n)/2n^3 - 1 n also converges.

Answers

The vertical distance between (7, -22) and (7, 12) is 34 units.

Explanation:

We can calculate the vertical distance by finding the difference between the y-coordinates of the two points.

Vertical distance = difference in y-coordinates = 12 - (-22) = 34

Therefore, the vertical distance between the two points is 34 units.

Answer: 34.
Explanation: The vertical distance between (7, -22) and (7, 12) is 34. Since -22 and 12 are different, (-22 is a negative number, meaning it is in a different quadrant on the coordinate plane and 12 is a positive number) you have to add them together, this is the distance. Remember, distance is always positive, so negative answers are immediately incorrect. (22 + 12 = 34.) So, the distance is 34. Hope that helps!

Tickets for all of the described charity raffle games cost $2 per ticket. identify the games in which a person who buys a ticket for each game every day for the next 400 days could expect to lose less than a total of $200.

Answers

Using the expected value formula the person should buy tickets for games 2 and 4, for all of the described charity raffle games cost $2 per ticket.

We can use the expected value formula to calculate the amount a person can expect to lose for each game. Let's denote the games as A, B, C, and D.

Game A: The probability of winning is 1/500, and the prize is $500. The expected value of a single ticket is (1/500)($500) - $2 = -$0.60, which means a person can expect to lose $0.60 for every ticket they buy.Game B: The probability of winning is 1/200, and the prize is $100. The expected value of a single ticket is (1/200)($100) - $2 = -$1, which means a person can expect to lose $1 for every ticket they buy.Game C: The probability of winning is 1/100, and the prize is $50. The expected value of a single ticket is (1/100)($50) - $2 = -$1.50, which means a person can expect to lose $1.50 for every ticket they buy.Game D: The probability of winning is 1/50, and the prize is $20. The expected value of a single ticket is (1/50)($20) - $2 = -$1.60, which means a person can expect to lose $1.60 for every ticket they buy.

To find the total amount a person can expect to lose after buying one ticket for each game every day for the next 400 days, we can simply multiply the expected value of each game by 400, and then add them up:

Expected loss from Game A = -$0.60 x 400 = -$240Expected loss from Game B = -$1 x 400 = -$400Expected loss from Game C = -$1.50 x 400 = -$600Expected loss from Game D = -$1.60 x 400 = -$640Total expected loss = -$240 - $400 - $600 - $640 = -$1880

Since the total expected loss is less than $200, a person who buys a ticket for each game every day for the next 400 days could expect to lose less than $200 by playing games A, B, and C. Game D is not a good choice, as a person could expect to lose more than $200 by playing that game alone.

Adding 12 apples to a basket initially containing c apples results in a total of 13.50 apples.

How can a real-world situation be represented by the equation 12 + c = 13.50?

The equation 12 + c = 13.50 can represent a real-world situation of purchasing items at a store and calculating the total cost. In this scenario, let's assume that 12 represents the price of a particular item, and c represents the additional cost, such as taxes or fees.

The equation states that when the additional cost is added to the base price of 12, the total cost becomes 13.50. This can occur when there is a sales tax or an additional charge applied to the base price. By solving the equation for c, we find that the additional cost is 1.50.

Therefore, in this situation, the real-world interpretation is that the item costs 12 dollars, and the additional cost, such as taxes, is 1.50 dollars, resulting in a total cost of 13.50 dollars.

You put $4500 into an account earning 6% interest compounded annually.


Write an equation to model the situation

Answers

The equation of this model situation with  $4500 into an account earning 6% interest compounded annually is  4500(1.06)ᵗ.

The equation to model the situation would be:

A = P(1 + r/n)ⁿᵗ

where A is the amount of money in the account after t years, P is the initial investment (which is $4500), r is the interest rate (which is 6% or 0.06 as a decimal), n is the number of times the interest is compounded per year (in this case, annually), and t is the number of years.

Plugging in the values, the equation becomes:

A = 4500(1 + 0.06/1)ⁿᵗ

Simplifying further, it becomes:

A = 4500(1.06)ᵗ

This equation can be used to find the amount of money in the account after any number of years.

(My question has a part A and part B)
The salesperson earns a 5%
commission on the first $5000
she has in sales. • The salesperson earns a 7. 5%
commission on the amount of her sales that are greater than. ​
Part A
This month the salesperson had $1,375
in sales. What amount of commission, in dollars, did she earn?​

Answers

A) The total commission she earned is $475

B) Total sales for commission of $1375 is $20000

How to calculate the amount of commission?

A) Total Commission = Commission 1+ Commission 2

Where:

Commission 1 = 5% of first $5000

Commission 2 = 7.5% of the amount left after $5000 is subtracted

thus

Commission 1 = $5000 * 0.05 = $250

Commission 2= $3000 * 0.075 = $225

Commission total = $250 + $225 = $475

The total commission she earned is $475

B) Total sales = Sales with 5% commission + Sales with 7.5% commission

Sales with 5% commission = $5000

Commission At 7.5% = Total commission -Commission with 5% =    $1375 - $250

Sales * 0.075 =  $1125

Sales with 7.5% commission = $15000

Total sales = $5000+$15000

Total sales = $20000

Total sales for commission of $1375 is $20000

√x+3
a.3x^1/2
b.(x+3)^1/2
c.x^1/2+3
d.(3x)^1/2

Answers

Answer:

b

Step-by-step explanation:

The expression √x+3 means the square root of x+3. We can rewrite this as (x+3)^(1/2), using the exponent rule that says taking the square root is the same as raising to the power of 1/2.

So the options become:

a. 3x^(1/2)

b. (x+3)^(1/2)

c. x^(1/2) + 3

d. (3x)^(1/2)

None of the other options match the given expression. So the correct answer is (b) (x+3)^(1/2).

Ac is a diameter of d. if mbdc = 150°, what is the measure of ab?

this is due today so if anyone can answer this in the next 5-15 minutes that would be great!

Answers

We know that the measure of AB is 240°.

Given that AC is a diameter of D and MBDC = 150°, we know that angle ABC is a right angle (90°) because it is inscribed in a semicircle.

Using the fact that the sum of angles in a triangle is 180°, we can find angle MBC:

MBC + 150° + 90° = 180°
MBC  = -60°

Since angle MBC is negative, we know that it must actually be 360° - 60° = 300°.

Finally, using the fact that angles on a straight line add up to 180°, we can find angle ABM:

ABM + MBC = 180°
ABM + 300° = 180°
ABM = -120°

Again, since angle ABM  is negative, we know that it must actually be 360° - 120° = 240°.

Therefore, the measure of AB is 240°.

A group of friends wants to go to the amusement park. They have no more than $
365 to spend on parking and admission. Parking is $16. 25, and tickets cost $38. 75 per person, including tax. Write and solve an inequality which can be used to determine p, the number of people who can go to the amusement park. ​

Answers

The group of friends can consist of at most 9 people, given the budget constraint and pricing can go to the amusement park.

The inequality to determine the number of people who can go to the amusement park can be written as: 38.75p + 16.25 ≤ 365.

Where p represents the number of people and the left-hand side of the inequality represents the total cost of admission and parking for p people.

The inequality is set up such that the total cost cannot exceed the given budget of $365.

To solve this inequality, we can first subtract 16.25 from both sides: 38.75p ≤ 348.75. Then, divide both sides by 38.75: p ≤ 9

To determine the maximum number of people who can go to the amusement park with a given budget,

we can write and solve an inequality based on the cost of parking and admission per person.

In this case, the inequality is 38.75p + 16.25 ≤ 365, and the solution is p ≤ 9.

a popular TV series is running for 10 seasons. You are buying the seasons from an online DVD service. If each season arrives at random, what is the probability that the first 5 seasons you receive in the mail are the first 5 seasons that were made, in the correct order?

Answers

The probability that the first 5 seasons you receive in the mail are the first 5 seasons that were made, in the correct order is given as follows:

p = 1/30240.

How to calculate a probability?

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

5 seasons are going to be shown from a set of 10, and the order is relevant, hence the permutation formula is used to obtain the total number of outcomes, as follows:

P(10, 5) = 10!/5!

P(10, 5) = 30240.

Only one of the outcomes has the correct seasons and order, hence the probability is given as follows:

p = 1/30240.

You should always measure your following distance in.

Answers

You should always measure your following distance in seconds. The correct answer for measuring following distance is A.  

It is important to keep a safe distance between vehicles on the road, which is known as following distance. Measuring following distance in seconds is a more reliable method than measuring it in car lengths or feet.

The recommended following distance is typically two to three seconds. This means that when the vehicle in front of you passes a fixed point on the road, you should not reach that same point before two to three seconds have elapsed.

Measuring in seconds is more effective as it takes into account the speed at which both vehicles are traveling. If you measure in car lengths or feet, it may not be accurate as the length of the cars may differ, and it does not account for the speed of the vehicles. By measuring in seconds, you can maintain a safe distance and reduce the risk of accidents or collisions.

A scale drawing of a famous statue uses a scale factor of 240:1. If the height of the drawing is 1.2 feet, what is the actual height of the statue?

288 feet
241.2 feet
238.8 feet
200 feet

Answers

The height of the statue is 288 feet.

The scale factor is 240:1

Or, the ratio of the height of the statue to the height of the drawing = 240:1.

This means, for 1 unit height of drawing, the height of the statue = 240 units

Or, for 1 feet height of the drawing, the height of the statue = 240 feet.

Let us suppose the actual height of the statue to be x.

The height of the drawing = 1.2 feet    (given)

So, the ratio of the height of the statue to the height of the drawing = x/1.2

But, the scale factor  = 240:1 = 240/1

240/1=x/1.2

⇒x=240×1.2

x=288

Hence, the height of the statue is 288 feet.
