SVETLANKA909090 [29]

Answer:

$84.80

Step-by-step explanation:

find the difference between accurate price and written price: 74 - 47 = 27

find written total (before Mrs. Taylor found mistake) by undoing the mean calculation: 82.55 x 12 = $990.60

the total expenses is $27 more than what they thought: 990.60 + 27 = 1017.60

divide accurate total by 12 to find mean: 1017.60 / 12 = $84.80

Answer:

c. A two-tailed test should be performed since the alternative hypothesis states that the parameter is not equal to the hypothesized value.

And p2 be the average score on a final exam who did not texted at all during the lectures for a particular class

According to the Cameron's point of interest, null and alternative hypotheses are:

$H_{0}:$ p1 = p2

$H_{a}:$ p1 ≠ p2

Two tailed test should be performed since the alternative hypothesis states that the parameter is not equal to the hypothesized value.

terrence made a sphere out of modeling clay. the sphere had a radius of 2 inches. approximately how much modeling clay did terre

navik [9.2K]

Amount of clay used = volume of the sphere

It is given that the radius of the sphere is 2 inches.

Volume of the sphere = $\frac{4}{3} \pi r^{3}$

$=\frac{4}{3} \pi (2^{3} )$

$=\frac{4}{3} \pi (8)$

$=\frac{32}{3} \pi$

Hence, the amount of modeling clay Terrence used $=\frac{32}{3} \pi$ cubic inches.
