Nookie1986 [14]

Answer: $A=2.5x^{2}$

Step-by-step explanation:

1. Let's write the following formula for calculate the area of a rectangle:

$A=yx$

Where $y$ is the lenght (the longer side) and $x$ is the width (the shorter side).

2. You know that the length is 2.5 times as long as the other side, which indicates a multiplication. Then:

$y=2.5x$

3. So, you must substitute $y$ into the equation for calculate the area of the rectangle and then you must simplify.

4. Then, you obtain the following expression:

$A=(2.5x)(x)\\A=2.5x^{2}$

ivann1987 [24]

Answer:96.97

Step-by-step explanation:

Given

mean height of women $\mu _w=64$

Standard deviation of height $\sigma _w=2.82$

mean height of men $\mu _=69.3$

Standard deviation of height $\sigma _m=2.71$

P $\left ( X$

P $\left ( \frac{x-\mu _w}{\sigma _w}\right )$

P $\left ( Z$

i.e. 0.9697=96.97 %
