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.
If you round 100.360 to the nearest whole number it'll be (100) if you see "100.500" i'll be 101 due to the decimals
Answer: 24y - 8w + 16
Step-by-step explanation:
Basically to remove the parenthesis you just distribute the -4 outside of the parenthesi and you get 24y - 8w + 16.
If this an angle on a straight line the answer is k=73°
