The air pressure of each tire in a group is normally distributed with a mean of 39.2 pounds per square inch(psi) and a standard deviation of 2.5 psi. If a tire in this group has a z score of -1.8, find its air pressure.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
