Answer:
the answer is that you would purchase 3 pens.
Step-by-step explanation:
if you buy 5 highlighters that would be
1.09 x 5 = 5.45
and then if you buy 3 pens that would be
0.69 x 3 = 2.07
if you add them together you get 7.52 :)
I think and x are parallel angles
Answer:
200%
Step-by-step explanation:
2 multiplied by 100
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
The angle between the legs labeled
and
is complementary to the angle with measure 31 degrees, so that angle has measure 90 - 31 = 59 degrees. Then
