The simplified expression is 64
Answer:
a= 79° because they are in the position of co interior and b°is 101 it's self because of VOA
Answer:
10.2
Step-by-step explanation:
See the image attached
It looks like you're given
Consider the geometric sum,
Multiply both sides by 1/2 :
Subtract this from S :
Solve for S :
The given sum is just 5 times S, so x = 1023 × 5 = 5115.
Answer:
We have to find the 90% confidence interval for the mean
Given sample size
Sample mean
Population standard deviation
Here the confidence level is 90% then
And
The 90% confidence interval is
Here is the critical value at 0.05
From the tables
Now the 90% confidence interval is =
=
=(3840.44, 4133.56)
Hence the 90% confidence interval for the mean is (3840.44, 4133.56)
