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
Answer:
The width of the room is 17.25 feet
Step-by-step explanation:
2(15.75+W)=66
Divide both sides by 2: 15.75+W=33
Subtract 15.75 from both sides: W=33-15.75=17.25
Hope this helps!
