Answer:

Step-by-step explanation:

Given quadratic equation is,

-32 = 2(x² + 10x)

-32 + 50 = 2(x² + 10x + 25)

18 = 2(x + 5)²

9 = (x + 5)²

± 3 = (x + 5)

x = -2 or x = -8

Answer:

The length for the 97th percentile for a man's arm span is 74.96 inches.

Step-by-step explanation:

We have a normal distribution for men's arm span, with mean of 68 inches and standard deviation of 3.7 inches.

The 97th percentil represents the value for which 97% of the observations are below.

We can search for the 97th percentile for the standard normal distribution. This will give a value z=1.88.

Then, we can convert this z-score to our distribution:

$X=\mu+z\cdot\sigma=68+1.88\cdot 3.7=68+6.96=74.96$
