Answer:
The point estimate for 
is 8.5 hours.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
In this problem
We are working with a sample of 81 adults, so the point estimae of the mean is the mean number of weekly hours that U.S. adults use computers at home.
So, the point estimate for is 8.5 hours.
A=bh
Where b is the base and h is the height
Answer: If two person had given your answer then there is a option of mark as brainliest. Click there in the option of mark as brainliest in which you like the answer most. If any one person has given answer then after some days you will a notification to mark his/her answer as brainliest. By this you can mark an answer as brainliest.
Step-by-step explanation:
A right angles is 90 degrees
if you mean 5/4 of the MEASURE of a right angle then
90 times 5/4 (because in math 'of' means multiply)
90 tmes 5/4=450/4=225/2=112.5 degrees
