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.

Answer:
17/20
Step-by-step explanation:
85% can easily be written as 85/100 and this is true, but we have to simplify to the simplest form.
An easy way to simplify is to divide the numerator and denominator by the GCF (Greatest Common Factor)
The GCF of 85 and 100 is 5.
85 ÷ 5 = 17
100 ÷ 5 = 20
We can no longer simplify 17/20 because 17 is prime so your final answer is 17/20!
