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

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

A triangular college pennant flag has a baes of 12 inches and a height of 30 inches how many square inches of wall space will yo

elena-14-01-66 [18.8K]

Answer:

$1080 \ in^2$

Step-by-step explanation:

-The cumulative area of the six is equivalent to the sum of their individual areas.

-Area of a triangle is given by:

$A=\frac{1}{2}bh\\\\b-base \ length\\h-\perp Height$

We substitute given values in the equation and multiply by the number of pennants:

$A=\frac{1}{2}bh\times 6\\\\=\frac{1}{2}\times 12\times 30\times 6\\\\=1080\ in^2$

Hence, the total area needed is $1080 \ in^2$
