The heights of women aged 30 to 35 are approximately Normal with mean 63 inches and standard deviation 2.4 inches. Men the same

gavmur [86]

Answer

given,

mean of women (μ)=63 inches

standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

$P(x>66)$

$P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}$

$P(x>66) = 1-P( z$

using z-table

$P(x>66)= 1 - 0.8944$

$P(x>66)=0.1056[/tex]for men[tex]P(x>66)$

$P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}$

$P(x>66) = 1-P( z$

using z-table

$P(x>66)= 1 - 0.0548$

$P(x>66)=0.9452$

if a triangular sail has a vertical height of 83 ft and horizantal length of 40 ft, what is the area of the sail?

Irina18 [472]

Answer:

A = 1660 $ft^{2}$

Step-by-step explanation:

Area of the sail or a triangle is base times height

A = $\frac{1}{2}$ (b x h)

Base is 40 ft (horizontal length)

Height is 83 ft (vertical height)

A = $\frac{1}{2}$ (b x h)

A = $\frac{1}{2}$ (40 x 83) = $\frac{1}{2}$ (3320) = 1660 $ft^{2}$
