A survey from summer 2019 found that the average American adult spent 2.25 hours a day in front of a computer outside of work, with a standard deviation of 0.75 hours. The survey also found that the population data is most likely normally distributed. a) What portion of adults are in front of a computer for less than 0 hours a day, outside of work?
b) Medical professions recommend spending no more than 2 hours in front of a computer each day. What portion of the population is on their computer more than the recommended amount?
c)What portion of adults spend between 1 and 5 hours a day in front of a computer each day, outside of work?

if this is really you s much. i only have 3 points left and i have 2 questions to ask

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

the answer is d.x= 90°

y= 50°

arc lm= 100°

i got this one chief
