Answer:
c 70
Step-by-step explanation:
supplementary means they equal 180
180 - 110 = 70
Answer:
Step-by-step explanation:
Sample variance when large number of samples are drawn we have tend to become a normal distribution.
Variance of the sample is different since variance
Var(x) = E(x^2)-{E(x)}^2
is the formula used for finding the variance of any sample.
But sampling distribution of variance requires repeating this process with the different samples several times.
So option A is not right
B is also not correct, C is wrong
D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.
is correct
Answer:
RS=19
Step-by-step explanation:
Simplify both sides of the equation.
V = 1/3 l h w
V = 1/3 (12)(15)(9)
V= = 540
answer 540 m^3
