Answer:
the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour
Step-by-step explanation:
The computation of the standard deviation of the speeds of cars is shown below;
The z score for the top 1% is 2.326
So,
= (75 - 61) ÷ standard deviation = 2.326
Standard deviation is
= 14 ÷ 2.326
= 6.0 miles per hour
Hence, the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour

For this case we have that the cost of each pizza is given by the following function:
Where:
r: It's the radius of the pizza
IF a pizza cost $26.32 we have:
We cleared the radius, using 
:
We choose the positive value:
So, the radius of the pizza is 
Then, the diameter is: 
Finally, the diameter of the pizza is:
