A variable is normally distributed with mean 14 and standard deviation 2.a. Find the percentage of all possible values of the variable that lie between 11 and 16.b. Find the percentage of all possible values of the variable that exceed 9.c. Find the percentage of all possible values of the variable that are less than 10.

the answer is two. hope this !

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
