Answer:

The perimeter is 74 meters

Step-by-step explanation:

By definition the perimeter of a rectangle is the sum of the lengths of its 4 sides.

The formula for calculating the perimeter of a rectangle is as follows:

$P = 2w + 2L$

Where P is the perimeter, w is the width and L is the length.

In this case we want to find P and we know that:

$w =16\ meters$

$L =21\ meters$

Therefore:

$P = 2(16) + 2(21)$

$P = 74\ m$

GarryVolchara [31]

Answer:

x-int=-8, y-int=2,-4

Step-by-step explanation:

for the x-int

you set x to 0 then solve the equation to get -8

for the y-int

you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4

The heights of women aged 20 – 29 in the United States are approximately Normal with mean 64.2 inches and standard deviation 2.8

Alenkinab [10]

Answer:

a) 0.64

b) -1.13

Step-by-step explanation:

We are given the following information in the question:

Women:

Mean, μ = 64.2 inches

Standard Deviation, σ = 2.8 inches

We are given that the distribution of heights of women is a bell shaped distribution that is a normal distribution.

Men:

Mean, μ = 69.4 inches

Standard Deviation, σ = 3.0 inches

We are given that the distribution of heights of men is a bell shaped distribution that is a normal distribution.

Formula:

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

5.5 feet = 66 inches

a) z‑score for a woman 5.5 feet tall

$x = 66\\\\\Rightqrrow z = \displaystyle\frac{66 - 64.2}{2.8} = 0.64$

b) z‑score for a man 5.5 feet tall

$x = 66\\\\\Rightqrrow z = \displaystyle\frac{66 - 69.4}{3.0} = -1.13$

The Wal-Mart buys sweatshirts for $38 each andsells them at a 60% increase in price. What is the amount of increase? What is the

Luba_88 [7]

To find the amount increase in price, you will calculate what 60% of the $38 is by multiplying 0.6 and 38

0.6 x 38 = $22.80 is the amount of increase.

The retail price is found by adding the increase to the cost.

$38 + $22.80 = $60.80.
