Suppose that a sample of 10 observations has a standard deviation of 3, then the sum of the squared deviations from the sample mean is 30.

TRUE or FALSE?

False

Step-by-step explanation:

Standard deviation (SD) = 3

Sample size (n) = 10

The standard deviation of a sample is determined as the square root of the sum of the squared deviations from the sample mean (S) divided by number of degrees of freedom (n-1). The sum of the squared deviations is:

The sum of the squared deviations from the sample mean is 81. Therefore, the statement is false.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

570, the answer is 570, hope it
