Please help!! Height of 10th grade boys is normally distributed with a mean of 63.5 in. and a standard deviation
of 2.9 in.
The area greater than the r-score is the probability that a randomly selected 14-year old boy exceeds 70 in.

What is the probability that a randomly selected 10th grade boy exceeds 70 in.?
Use your standard normal table.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
