Answer:

<u>1980 cubic inches</u> of water us in the tank if it is filled halfway with water.

Step-by-step explanation:

Given:

A tank in the shape of a rectangular prism has a length of 22 inches a width of 12 inches and a height of 15 inches.

Now, to find the water in the tank, if the tank is filled halfway with water.

So, to get the volume of tank as given above dimensions using formula:

Volume=length\times width\times height\\\\Volume=22\times 12\times 15\\\\Volume=3960\ cubic\ inches.

<em>Thus, the tank can be filled with 3960 cubic inches of water according to its volume.</em>

Now, to get the volume of water tank if the tank is filled halfway with water:

So, by dividing the volume of tank by 2:

\frac{3960}{2}=1980\ cubic\ inches.

Therefore, 1980 cubic inches of water us in the tank if it is filled halfway with water.

Kazeer [188]

Answer:

population standard deviation does not differ from 0.25

Step-by-step explanation:

The hypothesis :

σ² = 0.25²

σ² ≠ 0.25²

The Chisquare statistic, χ²: (n-1)*s²/σ²

Where s² = sample variance ; sample size, n = 30

Using calculator, the sample variance, s² = 0.1646

χ² = (n-1)*s²/σ²

χ²: (30 - 1) * 0.1646 / 0.25²

χ² = (29 * 0.1646) / 0.0625

χ² = 0.3292 / 0.0625

χ² = 5.2672

α = 0.05

Using the Pvalue from Chisquare calculator ; df = 29

Pvalue = 1

Since, Pvalue > α ; We fail to reject the null and conclude that population standard deviation does not differ from 0.25

Kevin work 0 during 1 day.

z=unit time
f(z)= number of hours kevin works in one week.

f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7

The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
