HELPPPP!!! LAST QUESTION!!!

Answer:

Step-by-step explanation:

A and B are complementary angles since C is right angle.

Given the values of the circumference and volume, the height  of the tree trump to the nearest tenth is 36.0in.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )

Given the data in the question;

First we determine the radius of the circular base.

Since circumference C = 2πr then r = C / 2π.

Hence, the volume of the cylinderical tree stump will be;

V = π × (C / 2π)² × h

V = π × ( C² / 4π² ) × h

V =  hC² / 4π

4πV = hC²

h = 4πV / C²

We substitute our given values into the expression

h = ( 4 × 3.14 × 20214in³ ) / (84in)²

h = 253887.84in³ / 7056in²

h = 36.0in

Therefore, given the values of the circumference and volume, the height  of the tree trump to the nearest tenth is 36.0in.

Remark

You need to choose between tan(30) and tan(60). Tan(60) = √3 which has a rational denominator (1).

Tan(60) = opposite / adjacent

Tan(60) = √3

Given

opposite = x

adjacent = 4

Theta = 60

Tan(theta) = √3

Solution

Tan(theta) = opposite / adjacent       Substitute values

√3 = x / 4                                            Multiply both sides by 4

4√3 = x

Answer

Answer: The two ratios that are equivalent to 4:18 include 2:9 and 8:36

Step-by-step explanation:

To be able to solve this question, we've to simplify the given ratio. Therefore, 4:18 will be reduced to the lowest term and this will be:

= 4/18 = 2/9

Also, when 4/18 is multiplied by 2 for both the numerator and denominator, the value will be:

= 4×2/18×2

= 8/36

Therefore, the correct options will be B(2:9) and E(8:36).

it is easy.....

first, convert this ratio into a fraction

4 : 18 = 4/18

now , equivalent fractions

= 4 = 4 × 2 , 4 × 3

18 = 18 × 2 ,18 × 3

now answer

= 4/18 , 8/36 , 12/54

again covert into ratio

= 4:18 , 8:36 , 12:54

Answer:

x = 14

Step-by-step explanation.

First I would use sine to find x's value. So ----> sin(30) = 7/x ----> x sin(30) = 7 ----> x = 7/sin(30) = 14.

You Can also find that x is equal to 14 by applying the 30, 60, 90, triangle rule. Becuase '7' opposes the 30 degree angle it is 1/2 the hypotenuse, if thats the case just multiply the 7 by 2 and you have the hypotenuse length.

Step-by-step explanation:

she wants to get information about the behavior of registered voters, but she surveys newspaper subscribers.

we have no clue, if they are registered voters.

if they are not, then the information does not apply.

if they are a mixture, then the survey mixed apples and oranges and does not provide usable information.

only if they all are also registered voters (which we don't know), this would provide some useful information.

but even in that last case I have to say she would have gotten information only about voters reading a specific newspaper. this particular newspaper might be one with especially short or long political commentaries. for better results the demographic sample population should cover multiple newspapers, or be newspaper independent (by picking the sample from voters registration lists instead of newspaper subscription lists).

Answer:

segment BF

Step-by-step explanation:

Part A

Reason:

The range, IQR, and the standard deviation are all measures of spread.

IQR stands for Interquartile Range. Unfortunately your teacher made a typo and wrote IRQ by mistake.

The symbol [tex]\sigma[/tex] is the greek letter sigma used to represent the population standard deviation.

The smaller these measures are, the more less spread out the values will be. This leads to the most consistent data set. Think of it like being on an archery range. The more consistent shots are closely clustered around the same point (not necessarily the center), while the less consistent shots are more randomly scattered about.

School B has the smallest range, IQR, and standard deviation of the three schools. Therefore, this school has the most consistent attendance.

=============================================================

Part B

Reason:

This school has the highest mean, and also the largest median, of all three schools. Both of these are measures of center or average. Compared to school B, this data set is a bit more spread out and not as consistent.

Answer:

a + (-c),  b,  c - (-b)

Step-by-step explanation:

First, identify the values of each point.

a = -1

b = 2

c = 3

Now, we can solve for the problems listed below the number line. We already know b = 2, so we don't need to solve for that one.

c - (-b) = 3 - (-2)

3 - (-2) = 3 + 2

= 5

--------------------------

a + (-c) = -1 + (-3)

-1 + (-3) = -1 -3

= -4

Now we can list the choices in order from least to greatest.

-4, 2, 5

aka; a + (-c),  b,  c - (-b)

Answer:

254.5 ft^3

Step-by-step explanation:

The volume of a cylinder is the area of the base times its height. To find the area of the base, since it is a circle, you would use the area formula of a circle([tex]\pi r^{2}[/tex] where r is the radius). So, the circle would have an area of 81 π. Now, multiplying this by the height, you get the volume. Since the height is just 1, the volume would be 81π which is 254.469004941. This rounded to the nearest tenth is 254.5.

The probability that the next on-the-job injury will occur within 10, 5, and 1 day are 0.632, 0.393, and 0.095

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We know the exponential distribution is given by;

[tex]\rm P(X < t)=1-e^{-\dfrac{1}{\mu}t}[/tex]

The probability that the next on-the-job injury will occur within 10 days:

[tex]\rm P(X < 10)=1-e^{-\dfrac{1}{10}10}[/tex]

P(X< 10) = 0.632

The probability that the next on-the-job injury will occur within 20 days:

[tex]\rm P(X < 5)=1-e^{-\dfrac{1}{10}5}[/tex]

P(X< 5) = 0.393

The probability that the next on-the-job injury will occur within 1 days:

[tex]\rm P(X < 1)=1-e^{-\dfrac{1}{10}1}[/tex]

P(X< 1) = 0.095

Thus, the probability that the next on-the-job injury will occur within 10, 5, and 1 day are 0.632, 0.393, and 0.095

Answer:

96 ft²

Step-by-step explanation:

As the base of the prism (the triangle) is an equilateral triangle (the sides are the same length), the surface area of the prism comprises:

Area of a rectangle = width × length

⇒ area of the rectangle = 3 ft × 10 ft = 30 ft²

Area of a triangle = 1/2 × base × height

⇒ area of the triangle = 1/2 × 3 ft × 2 ft = 3 ft²

Total surface area = 3 × area of the rectangle + 2 × area of the triangle

                              = 3 × 30 ft² + 2 × 3 ft²

                              = 90 ft² + 6 ft²

                              = 96 ft²

Answer: A binomial has a specified number of trials just before an experiment begins, and X counts the number of achievements acquired within that limited number. While a geometric, on the other hand, has a fixed number of successes and counts the number of attempts necessary to reach the first success. 

Step-by-step explanation:

This is only for the first question i don't know the second one sorry

The required difference between binomial and geometric models is In binomial there is to count of the number of successes, and in the geometric model, only the first success counts.

GIven that,
To determine how do binomial and geometric models differ and situations would a geometric model be better than a binomial model.

In mathematics, it deals with numbers of operations according to the statements.

Binomial distribution describes the number of successes k achieved in n trials and Given a finite number of trials, the geometric distribution is useful for calculating the chance of success.

Before an experiment starts, a binomial has a set number of trials, and X counts the number of successes attained within that fixed number. A geometric, on the contrary, count the number of efforts required to attain the first success and has a set number of successes.

The experiment can have an infinite number of attempts before success, unlike the binomial distribution which has a fixed number of trials, hence the geometric distribution is useful to describe the number of failures before the first success in such a sequence of trials.

Thus, the required difference between binomial and geometric models is In binomial there is to count of the number of successes, and in the geometric model, only the first success counts.

Answer:

Step-by-step explanation:

Answer to first question = her mistake was that she wrote the constant to be 10 whereas the constant is actually -10 once you rearrange the equation to look like a quadratic equation.

Quadratic equations are written in form of ax^2 + bx + c = 0

You are given x^2 + 3x = 10, first you need to bring the constant c (10) to the left side (by subtracting 10 on both sides).

x^2 + 3x - 10 = 0

c = -10

The 104 adults and 105 youth admissions were purchased if the admission fee is $8.00 for an adult and $4.50 for a youth.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

At the local fair, the admission fee is $8.00 for an adult and $4.50 for a youth.

Let's suppose the number of admission of adults is x and for youth is y, then,

x + y = 209 ...(1)

8x + 4.50y = 1304.5 ...(2)

After solving the above two linear equation, we get:

x = 104

y = 105

Thus, the 104 adults and 105 youth admissions were purchased if the admission fee is $8.00 for an adult and $4.50 for a youth.
