What is the volume of the prism

almond37 [142]

The volume of a rectangular prism or cube is: Length × Width × Height

In this case,

- the length of the prism is 2 feet

- the width of the prism is 1.5 feet

- the height of the prism is 1.5 feet

Multiply the above to find the volume: 2 × 1.5 × 1.5 = 4.5 ft³

Keep in mind that volume is represented in cubic units!

The athletic departments at 10 randomly selected U.S. universities were asked by the Equal Employment Opportunity Commission to

Lesechka [4]

Answer: Mean = 3.5 , median = 2.5, mode = 2, geometric mean = 2.74

Median is the most appropriate measure of central tendency.

The least appropriate = mean

Yes there is an outlier.

Step-by-step explanation:

Given responses : 5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

First arrange them in increasing order, $\sqrt[10]{1\times1\times2\times2\times2\times3\times4\times5\times5\times10 }\\\\=\sqrt[10]{24000} \approx2.74$

Its sum = 35

Mean of n observations = (Sum of observations) ÷ n

Mean = (35) ÷ 10

=3.5

Here n =10 (even)

Median = average of middle most numbers = $\dfrac{2+3}{2}=\dfrac52=2.5$

Mode = most repeated number = 2 (thrice)

geometric mean = $\sqrt[n]{x_1\times x_2\times.... x_n}$

10 is an outlier as it is very large as compare to other numbers.

When outlier is present in data , the median is the most appropriate measure of central tendency.

Mean affected badly by the outlier so it the least appropriate.

What is the product of -2x^3+x-5 and x^3-3x-4 ? (a) Show your work

saul85 [17]

Answer:

-3x3 - 2x - 4

Step-by-step explanation:

((((2•(x3))+x)-5x3)-3x)-4

(((2x3 + x) - 5x3) - 3x) - 4

Pulling out like terms :

4.1 Pull out like factors :

-3x3 - 2x - 4 = -1 • (3x3 + 2x + 4)

Polynomial Roots Calculator :

4.2 Find roots (zeroes) of : F(x) = 3x3 + 2x + 4

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 4.

The factor(s) are:

of the Leading Coefficient : 1,3

of the Trailing Constant : 1 ,2 ,4

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 -1.00

-1 3 -0.33 3.22

-2 1 -2.00 -24.00

-2 3 -0.67 1.78

-4 1 -4.00 -196.00

-4 3 -1.33 -5.78

1 1 1.00 9.00

1 3 0.33 4.78

2 1 2.00 32.00

2 3 0.67 6.22

4 1 4.00 204.00

4 3 1.33 13.78

Polynomial Roots Calculator found no rational roots

Final result :

-3x3 - 2x - 4
