A box contains nine tickets labeled with numbers. The number on the tickets are -9, -8, -7, -6, -3, -1, 1, 2, 8.

Required:
a. The expected value of the sample sum of the ticket labels in 11 independent random draws with replacement from the box is .
b. The standard error of the sample sum of the ticket labels in 11 independent random draws with replacement from the box is .
c. The expected value of the sample mean of the ticket labels in 11 independent random draws with replacement from the box is .
d. The standard error of the sample mean of the ticket labels in 11 independent random draws with replacement from the box is .

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

i would love   to but there is no graph shown

i am so sorry
