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

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

What is the volume of the prism?

SOVA2 [1]

Answer:

148 in³

Step-by-step explanation:

The equation for the volume of a cube is $V = a^{3}$

Here, $a = \frac{1}{3}$ .

$V=\frac{1}{3} ^{3}$

$V = \frac{1}{27}$

So, the volume of each cube is $\frac{1}{27}$ in.

The prism is filled completely with 3996 of these cubes.

$3996*\frac{1}{27} = 148$

The volume of the prism is 148 in³.
