Find the population mean or sample mean as indicated. population: 44, 22, 1111, 1717, 2121

1 answer:

4 0

The mean of the sample given by 44,22,11,17,21 will be given by:
$\mu= \frac{\Sigma x_i}{n}$
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23

Answer:

(x,y) --> (x+4, y-5)

Step-by-step explanation:

A is correct. B can be represented as x+4, y - 5 because the x values shifted 4 to the right (a positive shift so x+4) and the y values shifted 5 down (a negative shift so y-5)

A cylinder has a radius of 30 ft and a height of 19 ft. What is the exact surface area of the cylinder?

Ad libitum [116K]

$A=2\pi r(r+h)\\
A=2\pi\cdot30\cdot(30+19)\\
A=60\pi\cdot49\\
A=2940\pi\hbox{ ft}^2$
