A square has an area of 16x^2 square inches. If the sides of the square were to increase by 2 units, what is the new area of the

kykrilka [37]

Answer:

16x² + 64x + 64

Step-by-step explanation:

Given

A = 16x²

Increasing the sides by 2, substitute x = x + 2 into A

A = 16(x + 2)² ← expand factor using FOIL

= 16(x² + 4x + 4 ) ← distribute

= 16x² + 64x + 64

Zolol [24]

Answer:

The probability that the person is between 65 and 69 inches is 0.5403

Step-by-step explanation:

Mean height = $\mu = 66$

Standard deviation = $\sigma = 2.5$

We are supposed to find What is the probability that the person is between 65 and 69 inches i.e.P(65<x<69)

$Z=\frac{x-\mu}{\sigma}$

At x = 65

$Z=\frac{65-66}{2.5}$

Z=-0.4

Refer the z table for p value

P(x<65)=0.3446

At x = 69

$Z=\frac{69-66}{2.5}$

Z=1.2

P(x<69)=0.8849

So,P(65<x<69)=P(x<69)-P(x<65)=0.8849-0.3446=0.5403

Hence the probability that the person is between 65 and 69 inches is 0.5403
