Answer:

1) A

2) I

3) G

4) B

Step-by-step explanation:

1)

Bottom side: 7c - 1

Tall side: 6c + 2

P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2

P = 26c + 2

2)

P = 26c + 2

P = 26(5) + 2

P = 132

3)

P = 2(l + w)

P = 2(3d - 2 + 5d + 1)

P = 16d - 2

4)

P = 16d - 2

P = 16(3) - 2

P = 46

Use the net to find the lateral area of the cylinder. Give your answer in terms of pi.

Zinaida [17]

<u>Answer:</u>

The correct answer option is 153 $\pi mm^2$ .

<u>Step-by-step explanation:</u>

We are given a cylinder with a radius of 4.5 mm and a height of 17 mm and we are to find the lateral area of this cylinder.

We know that the formula of the lateral area of a cylinder is given by:

Lateral area of cylinder = $2 \pi r h$

Substituting the given values in the formula to get:

Lateral Area = $2\pi *4.5*17$ = 153 $\pi mm^2$

In the library on a university campus, there is a sign in the elevator that indicates a limit of 16 persons. Furthermore, there

Elis [28]

Answer:

a) 150 pounds

b) 6.75

c) 156.25

d) 0.177

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 150 pounds

Standard Deviation, σ = 27 pounds

We are given that the distribution of weight of persons on campus is a bell shaped distribution that is a normal distribution.

a) expected value of the sample mean of their weights

$\bar{x} = \mu = 150\text{ pounds}$

b) standard deviation of the sampling distribution

$\dfrac{\sigma}{\sqrt{n}} = \dfrac{27}{\sqrt{16}} = 6.75$

c) average weight for these 16 people will result in the total weight exceeding the weight limit of 2500 points

$\dfrac{\text{Limit}}{\text{Number of people}} = \dfrac{2500}{16} = 156.25$

d) P(sample of 16 persons on the elevator will exceed the weight limit)

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(x > 156.25)

$P( x > 156.25) = P( z > \displaystyle\frac{156.25 - 150}{6.75}) = P(z > 0.9259)$

$= 1 - P(z \leq 0.9259)$

Calculation the value from standard normal z table, we have,

$P(x > 610) = 1 - 0.823 = 0.177 = 17.7\%$

0.177 is the probability that a random sample of 16 persons on the elevator will exceed the weight limit.
