What is the volume of the prism? Enter your answer in the box as a mixed number in simplest form.
Musya8 [376]
The volume prism refers to the number of cubic units that will exactly fill the figure. The volume of a rectangular prism can be found or calculate by using the formula V=Bh, where B represents to the area of the base or in other words the length and width of the rectangle.

In this exercise is given that the measurements of a prism are 2ft, 3/2ft, and 3/2ft; and it is asked to find its volume. In order to find the volume of the prism, you should substitute the given values into the previous mention formula.
V=Bh
V=(2ft)(3/2ft)(3/2ft)
V=9/2ft^3 or 4 1/2ft^3

The volume of the prism is 4 1/2ft^3 as a mixed number.

1/16^3x=64^2(x+8)<br> Solve for x.
SSSSS [86.1K]

Answer:

x = -4

Step-by-step explanation:

16 = 4*4 = 4²

64 = 4 * 4* 4 = 4³

(\dfrac{1}{16})^{3x}=64^{2*(x+8)}\\\\\\(16^{-1})^{3x}=64^{2x + 16}\\\\\\16^{-3x}=64^{2x +16}\\\\(4^{2})^{-3x}=(4^{3})^{2x+16}\\\\4^{-6x}=4^{6x +48}

As bases are same, compare exponents

6x + 48 = -6x  

Subtract 48 from both sides

6x = -6x - 48

Add '6x' to both sides

6x + 6x = -48

12x = -48

Divide both sides by 12

x = -48/12

x = -4

In hypothesis​ testing, does choosing between the critical value method or the​ P-value method affect your​ conclusion? Explain.
slamgirl [31]

Answer:

A.

Step-by-step explanation:

​Yes, because the critical value method uses critical​ value(s) to identify the rejection​ region(s). The​ P-value method compares the​ P-value with the level of significance alpha.

Explanation:  When you reduce your significance value, the critical value either gets smaller, or larger depending on the tails.  This means that your test statistic would also have to get smaller or larger depending on the tail in order to reject the null hypothesis.

At test that rejected the null hypothesis at 5% may not reject it at 1%

Which of the b-values satisfy the following inequality? 5 &lt; b-3 <br>a. b=8<br>b. b=9<br>c. b=10​
lilavasa [31]

Answer:

the values 9 and 10 satisfy the given inequality.

Step-by-step explanation:

Given inequality is:

5

In order to find, which value of b satisfies the given inequality, we have to put the given values one by one in the inequality

Putting b = 8

5

The inequality is not true for b=8.

Putting b=9

5

As the inequality is true for b=9, it satisfies the inequality.

Putting b=10

5

As the inequality is true for b=10, it satisfies the inequality.

Hence,

the values 9 and 10 satisfy the given inequality.
