Each of the following linear equations defines y as a function of x for all integers x from 1 to 100. for which of the following equations is the standard deviation of the y-values corresponding to all the x-values the greatest?

(a) y = x/3
(b) y = x/2 + 40
(c) y = x
(d) y = 2x + 50
(e) y = 3x - 20

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
