So add all the numbers together (20 + 22 + 28 + 35 + 47 + 90) and you'll get 242. Then you take the number and divide it by the numbers in your set (you have 6 numbers so you'll divide by 6) 242/6. The answer would be 40.3333333 (repeating decimal). I hope this helps!

Hi there!

First, line them up from least to greatest. (20, 22, 28, 35, 47, 90). Now add all them up. 20 + 22 + 28 + 35 + 47 + 90 = 242. Now divide by how many numbers are in the set, (6). 242 / 6 = 40.

Hope this helps!! ♥♥

An open-top rectangular box with square base is to be made from 100 square feet of material, as shown.
-Dominant- [34]

The largest possible volume of the given box is; 96.28 ft³

<h3>How to maximize volume of a box?</h3>

Let b be the length and the width of the base (length and width are the same since the base is square).

Let h be the height of the box.

The surface area of the box is;

S = b² + 4bh

We are given S = 100 ft². Thus;

b² + 4bh = 100

h = (100 - b²)/4b

Volume of the box in terms of b will be;

V(b) = b²h = b² * (100 - b²)/4b

V(b) = 25b - b³/4

The volume is maximum when dV/db = 0. Thus;

dV/db = 25 - 3b²/4

25 - 3b²/4 = 0

√(100/3) = b

b = 5.77 ft

Thus;

h = (100 - (√(100/3)²)/4(5.77)

h = 2.8885 ft

Thus;

Largest volume = [√(100/3)]² * 2.8885

Largest Volume = 96.28 ft³

Explain a thought process you might use when trying to find the additive or multiplicative inverse of a number or expression. ..
gizmo_the_mogwai [7]
Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other. 


<span>......................................... IF A + B = 0 , they are the additive inverse of each other. 
</span>

<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>

<span>......................................... A.B = 1 , they are the multiplicative inverse of each other. 
</span>

<span>Example of: </span>

<span>Additive inverses :................ 5 + ( - 5 ) = 0 </span>

<span>Multiplicative inverses...........5 x 1/5 = 1 </span>

zimovet [89]
I think the correct answer from the choices listed above is the third option. <span>If a statistic used to estimate a parameter is such that the mean of its sampling distribution is equal to the actual value of the parameter, then it is a biased estimator. Hope this answers the question.

Find the slope line (-2 -1) and (-4 -7)
Alenkinab [10]

Answer:

m=3

Step-by-step explanation:

Slope formula

m=\frac{y_2-y_1}{x_2-x_1}

Here

(x_1, y_1) = (-2, -1) \ \ and \ \ (x_2, y_2) = (-4, -7)

Slope can be calculated as

m=\frac{-7-(-1)}{-4-(-2)}

m= \frac{-6}{-2} \\m=3
