Suppose the people living in a city have a mean score of 5151 and a standard deviation of 33 on a measure of concern about the environment. assume that these concern scores are normally distributed. using the 50%minus−34%minus−14% figures, approximately what percentage of people have a score (a) above 5151, (b) above 5454, (c) above 4545, (d) above 4848, (e) below 5151, (f) below 5454, (g) below 4545, and (h) below 4848?

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

3+x

step-by-step explanation:

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

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
