Answer:

Over the next decade the Ogallala aquifer will be completely depleted and will affect portions of the central and southern High Plains Aquifer (HPA). The Ogallala Aquifer is one of the largest bodies of water in the United States and is is generally used by farmers for irrigation of crops. As the continuous depletion of the aquifer occurs, it may become problematic for agricultural industries to sustain their farming.

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Elan Coil [88]

Answer:

(40/3)*pi

Step-by-step explanation:

lets first find the area of the little circle

A=pi*r^2

A=pi*3^2

A=9pi

Now, lets find the area of the big circle

A=pi*r^2

A=pi*(3+4)^2

A=pi*7^2

A=49pi

now lets subtract the area of the little circle from the area of the big circle

49pi-9pi=40pi, now we found the area of the "bagel)

lets find what portion of the bagel is the shaded region

120/360=1/3

now lets multiply the bagel area by the fraction

40pi*(1/3)=

(40/3)*pi   or  (40*pi)/3

Answer:

E. 2.

Step-by-step explanation:

The sphere will have a diameter equal to the side length of the cube.

The side length of the cube is ∛64 = 4  so the diameter of the sphere = 4.

The radius = 1/2 * 4 = 2.

The National Assessment of Educational Progress (NAEP) gives a math assessment every year to 12th graders in the U.S. On the mat
amid [387]

Answer:

The correct answer is option 2.

Step-by-step explanation:

In this case we need to test whether young men nationwide have a mean score below 275 in the National Assessment of Educational Progress math assessment.

The hypothesis is defined as follows:

<em>H₀</em>: <em>μ</em> = 275 vs. <em>Hₐ</em>: <em>μ</em> < 275

The significance level of the test is <em>α</em> = 0.05.

The <em>p</em>-value of the test is computed as, <em>p</em>-value = 0.20.

Decision rule:

A small <em>p</em>-value (typically ≤ 0.05) specifies solid proof against the null hypothesis (<em>H₀</em>), so you discard the null hypothesis.

A large <em>p</em>-value (> 0.05) specifies fragile proof against the null hypothesis, so you fail to discard the null hypothesis.

<em>p</em>-value = 0.20 > <em>α</em> = 0.05.

The null hypothesis was failed to rejected at 5% level of significance.

Thus, it can be concluded that there is not enough evidence to conclude that the mean score is less than 275 for young men nationwide.

Thus, the correct answer is option 2.
