VARVARA [1.3K]

Answer:

Less than 264.44 days would be for the shortest 20%

Step-by-step explanation:

Given that X, the length of a human pregnancy is normally distributed with a mean of 272 days with a standard deviation of 9 days (Bhat & Kushtagi, 2006).

X is N(272, 9)

Corresponding Z score would be for any x

$z=\frac{x-272}{9}$

We have to find out the shortest 20%

Corresponding z score i.e. z score 20th percentile is given by

-0.84

corresponding x score is

$272-0.84*9\\= 264.44$

Less than 264.44 days would be for the shortest 20%

bellamy is building a gate to put on a fence. the gates measurements are 7 feet by 7 feet a diagonal wooden brace is going to be

Rama09 [41]

The length of the diagonal is the hypotenuse of the fence

The length of the wood is $7\sqrt{ 2$ yards

<h3>How to determine the length of the wood?</h3>

The dimensions of the fence are:

7 ft by 7 ft

The length (L) of the diagonal is calculated using:

$L = \sqrt{a^2 + b^2$

This gives

$L = \sqrt{7^2 + 7^2$

Express as products

$L = \sqrt{7^2 * 2$

Express as radical

$L = 7\sqrt{ 2$

Hence, the length of the wood is $7\sqrt{ 2$ yards
