Answer:
The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).
Step-by-step explanation:
Confidence interval:
Sample mean plus/minus the margin of error.
In this question:
Mean of 23.
Margin of error 2.1.
Then
23 - 2.1 = 20.9
23 + 2.1 = 25.1
The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).
Answer:
64π^2 cubic inches
Step-by-step explanation:
The question is not complete, the shapes are not given
Diameter of base= 16π
Radius of base= 8π
Height of cylinder = 8 inches
Let us find the volume of the cylinder
V= πr^2h
V= π* (8π)* 8
V= 64π^2 cubic inches
Hence the volume of the cylinder is 64π^2 cubic inches
I think,
Road C equals 650, because road A is parallel it must equal the same.
So, 650 + 650 = 1,300
We already know that Road D equals 2,000, add it all up.
1,300 + 2,000 = 3,300
Hope this helped :)
Did you mean to write x? either way, x= 5 and x = 3 or if you wanna use Y. Y = 5 Y = 3
