What is the means-to-MAD ratio of the two data sets, expressed as a decimal to the nearest tenth? Data Set 1: {85, 83, 90, 70, 87} Data Set 2: {75, 74, 68, 83, 80}

Answers

Answer 1

Answer: Here is what I got for the first one. MAD= 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|) =1/5(|85-83|+|83-83|+|87-83|+|90-83|+|70-83|) =1/5(2+0+4+7+13)) =5.2 And for the second one I got, MAD= 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|) =1/5(|75-76|+|74-76|+|68-76|+|83-76|+|80-76|) =1/5(1+2+8+7+4)) =4.4

How do you solve n+2=-14-n

Answers

The requried solution to the equation n + 2 = -14 - n is n = -8.

To solve the equationn + 2 = -14 - n, we can use basic algebraic operations to isolate the variable n on one side of the equation. Here's how:

Start with the given equation: n + 2 = -14 - n

To eliminate the negative sign in front of the second term, we can add n to both sides of the equation:

n + n + 2 = -14 - n + n

Simplifying, we have:

2n + 2 = -14

Next, we want to isolate the variable term, so let's get rid of the constant termon the left side by subtracting 2 from both sides:

2n + 2 - 2 = -14 - 2

Simplifying, we get:

2n = -16

Finally, to solve for n, we divide both sides of the equation by 2:

(2n) / 2 = (-16) / 2

This simplifies to:

n = -8

Therefore, the solution to the equation n + 2 = -14 - n is n = -8.

|18 – 6|

Answers

Answer:

Step-by-step explanation:

This is an absolute value expression. The absolute value of a number is its magnitude without regard to its sign.

|18 - 6|

|12| --- simplify 18 - 6

12 --- the absolute value of 12 is just 12

Why can there be two vertical cross sections for a right rectangular prism and only one horizontal cross section?

Answers

The horizontal cross section is parallel to the base. It is always a single, constant sized, rectangle. The vertical one is not restricted to be parallel to any face. So, its size will vary as the prism is rotated. It could vary between a size, the other one or the diagonal (largest), however the height remains constant.

Select the explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 ak = 6 • 3k – 1
ak = 3 • 6k – 1
ak = 6 • 3k
ak = 3 • 6k
