Answer:

0.0475

Step-by-step explanation:

First find the z-score.

z = (x − μ) / σ

z = (125 − 100) / 15

z = 1.67

Use a calculator or chart to find the probability.  Using a chart:

P(Z > 1.67) = 1 − P(Z < 1.67)

P(Z > 1.67) = 1 − 0.9525

P(Z > 1.67) = 0.0475

Answer: P=47 inches

Step-by-step explanation:

First, you have to find the other side lengths. Two of the sides are equal to 20 because this is a rectangle. The first blank would be 20 because 20 times the other side length is equal to 70. Then you would divide 70 by 20 which would equal x. x would equal 3.5 in. Then the perimeter would be:

2(20)+2(3.5)=P

P=47 inches

Let f(x) = 5x – 8 and g(x) = 9 - 6x2.<br> -<br> (f o g)(-3) =
MArishka [77]

Step-by-step explanation:

f(x) = 5x - 8

g(x) = 9 - 6x²

= (fog)(-3)

= f( g(3) )

= 5x - 8

= 5(9 - 6x²) - 8

= 5(9 - 6(-3)² ) - 8

= 5(9 - 54) - 8

= 5(-45) - 8

= -225 - 8

= -233

(fog)(-3) = -233
