The weight of oranges growing in an orchard is normally distributed with a mean weight of 7.5 oz. and a standard deviation of 1.5 oz. Using the empirical rule,
determine what interval would represent weights of the middle 95% of all oranges
from this orchard.

this is false ^.^ lol

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

add 8+12 to get a simplified answer of 12r-20

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
