a) is something that certain undergraduate majors at your university/college other than economics seem to have an [infinity] amount of.
b) in the context of the sample variance formula means that estimating the mean uses up some of the information in the data.
c) ensure that s^2y = σ^ 2y .
d ) are (n-2) when replacing the population mean by the sample mean.

10

step-by-step explanation:

7+3=10

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
