Answer:
-2x-10
Step-by-step explanation:
just distribute the -2 :)
Answer:
1024pi/3
Step-by-step explanation:
to find the volume of a sphere you use the equation 4/3*pi*r^3
4/3*pi*8^3
4/3*pi*512
2048/3 pi
This is the volume of the whole sphere but we only need half so we can just divide by 2.
(2048/3 pi)/2
1024/3 pi
Answer:
a. A researcher wants to compare the hand–eye coordination of men and women. She finds a random sample of 100 men and 100 women, and measures their hand–eye coordination = paired samples
b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without tenure. = independent samples
Explanation:
Paired-samples t tests compare scores on two different variables but for the same group of cases; independent-samples t tests compare scores on the same variable but for two different groups of cases.
Answer:
7/3
Step-by-step explanation:
The base is 44 cut that in half to get the radius, R=22 height=6
fill in v=1/3 x 3.14 x r^2 x H
v = 1/3 x 3.14 x 22^2 x 6
22 x 22= 484
484 x 6 = 2904
2904 x 3.14= 9118.56
9118.56 x 1/3 = 9118.56/1 divided by 2735568/3 = 300
