The distance around a CIRCLE is called the circumference
9x-3 because you combine like terms
EXPLANATION
We have that the area under the probability density curve is equal to 1.
As the width of the rectangle is 2, the height must be 1/2.
Then, the probability that X is between 0.2 and 1.54 is as follows:
P = 1/2 ( 1.54 - 0.2 )
= 0.67
Hence, the probability is 0.67
Answer: 24 minutes it the correct answer you would do 40(60) = 2,400
Deducte the 0's and you have 24
