Answer:


Step-by-step explanation:
we are given


we have to find f/g
we can write as

now, we can plug values
and we get

so,

we know that denominator can not be zero
so,

now, we can solve for x


Divide both sides by 5
and we get

Answer:

Answer:
The probability that a randomly chosen tree is greater than 140 inches is 0.0228.
Step-by-step explanation:
Given : Cherry trees in a certain orchard have heights that are normally distributed with
inches and
inches.
To find : What is the probability that a randomly chosen tree is greater than 140 inches?
Solution :
Mean -
inches
Standard deviation -
inches
The z-score formula is given by, 
Now,





The Z-score value we get is from the Z-table,


Therefore, the probability that a randomly chosen tree is greater than 140 inches is 0.0228.
