Answer:

Mean = $\sum x P(x) = 36.86$

Standard deviation = $\sum x^2P(X)=1360.9$

Step-by-step explanation:

x P(x) $x \times P(x)$ $x^2 \times P(x)$

33 0.02 0.66 21.78

34 0.06 2.04 69.36

35 0.1 3.5 122.5

36 0.2 7.2 259.2

A cone has a diameter of 3 inches the cone holds 12 cubic inches of water to the nearest in what is the height

LUCKY_DIMON [66]

Answer:

5 inches

Step-by-step explanation:

A cone's volume can be found using the formula $V = \frac{1}{3} \pi r^2 h$ . If the cone has a diameter of 3 inches then its radius is half r= 1.5 inches. Substitute r = 1.5 and V = 12 cubic inches.

$V = \frac{1}{3} \pi r^2 h \\12 = \frac{1}{3} \pi (1.5)^2 h \\12 = \frac{1}{3} \pi (2.25) h\\12 = 2.355h\\5.10 = h$

This means the height of the cone is 5.10 inches or to the nearest inch 5 inches.
