What is the volume of the following triangular prism?
Firdavs [7]

Answer:

Step-by-step explanation:

In order to calculate the volume of a triangular prism you need 2 things:

The triangles area and the prism's height.

Any prism's volume can be calculated by multiplying its base area with its height.

The Area of a triangle can be calculated in different ways.

The most used and "normal" way is:

(width * height) / 2

Another way is by using herons formula, which looks like this:

a, b, c = different sides of the triangle (length)

s = (a + b + c) / 2

a = \sqrt{s (s-a)(s-b)(s-c)}

When you have the prism's base area (b_{a}) you just have to multiply:

b_{a}*h=V

(V = volume)

If you have any questions, just ask them in the comments below.

Have a good day! (●'◡'●)

Answer:

2(x+4)/(x+3)(x-4)(x+4) and 1(x+3)/(x+3)(x-4)(x+4)

Step-by-step explanation:

Factor x^2-x-12: (x+3)(x-4)

Factor x^2-16: (x+4)(x-4)

So, LCD would be (x+3)(x-4)(x+4)

Rewritten: 2(x+4)/(x+3)(x-4)(x+4) and 1(x+3)/(x+3)(x-4)(x+4)

I hope this helped and have a good rest of your day!

VARVARA [1.3K]

Answer:

(1) The between groups degrees of freedom is 2.

(2) TRUE.

(3) The correct option is (a).

Step-by-step explanation:

(1)

The between groups degrees of freedom for the study is:

\text{df}_{B}=k-1\\=3-1\\=2

Thus, the between groups degrees of freedom is 2.

(2)

The hypothesis for he one-way ANOVA is:

<em>H</em>₀: All the means are equal.

<em>Hₐ</em>: At least one of the mean is not equal.

The output of the ANOVA test is attached below.

The <em>p</em>-value of the test is 0.00005.

<em>p</em>-value = 0.00005 < <em>α</em> = 0.05

Thus, the result is statistically significant.

The statement is TRUE.

(3)

As the <em>p</em>-value of the test is less than the significance level, the researcher should make the decision to reject the null hypothesis.

The correct option is (a).
