Answer:
24
Step-by-step explanation:
<u>First, we round the fractions. </u>
If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.
7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.
1/8 is less than half so we round down and remove the fraction so we are left with 10.
<u>Then we add.</u>
14+10=24
Well... that's to hard for me sadly when I learned a lot how to do that, i'll give you this though when you going from bigger to smaller you divide, when you going smaller to bigger you times.
Good luck though ;)
Answer:
it looks like a positive correlation?
Step-by-step explanation:
I really don't know much but it looks like the y in increasing in a positive direction when the x is as well
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
