What is the MAD of 15, 17, 15, 17, 21, 17, 15, 21, 20, and 18

Answers

Answer 1

Answer: Okay i will just do this step by step...

1st.) Find the mean of all the values.
Of course finding the mean is adding all the numbers up together and dividing by the number of numbers present.
So add all the numbers...
15 + 17 + 15 + 17 + 21 + 17 + 15 + 21 + 20 + 18 = 176
Now divide by 10 since there are ten numbers.
176 ÷ 10 = 17.6

2nd.) subtract the mean from each value, (ignore the minus signs in our answer, they are not needed, our answer will be a positive number!!!)
So...
15 - 17.6 = 2.6
17 - 17.6 = 0.6
15 - 17.6 = 2.6
17 - 17.6 = 0.6
21 - 17.6 = 3.4
17 - 17.6 = 0.6
15 - 17.6 = 2.6
21 - 17.6 = 3.4
20 - 17.6 = 2.4
18 - 17.6 = 0.4

Now our new Set of numbers is...
2.6, 0.6, 2.6, 0.6, 3.4, 0.6, 2.6, 3.4, 2.4, 0.4

3rd.) So now we have to take those numbers and find the Mean out of those... Soo first add them up together.
2.6 + 0.6 + 2.6 + 0.6 + 3.4 + 0.6 + 2.6 + 3.4 + 2.4 + 0.4 = 19.2
Now divide by the number of numbers present or in this case (10)
soooo
19.2 ÷ 10 = 1.92

sooooo
MAD = 1.92

Solve: 493x = 3432x+1

Answers

Answer:

x = -1/2939

Step-by-step explanation:

First, you isolate x (subtract 3432x from both sides): -2939x = 1

Then, you divide both sides by -2939: x = - 1/2939

The area of a rectangle is 256.5m. If the length is 18m what is the perimeter of the rectangle?

Answers

The area of a rectangle equals length times height. (A=LH)

A=256.5 L=18

Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)

next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.

So, it is 256.5/18 equaling H

256.5 divided by 18 is... 14.25

That means the height is 14.25 an the length is 18.

the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.

So you have two sides that are 14.25 and two that are 18 meters long.

14.25+14.25+18+18 equals the perimeter then.

So the answer would be... 64.5!

area = l x b

thus, 256.5 = 18 x b

thus b = 256.5/18
= 14.25

thus, breadth is 14.25 meters

Now perimeter = 2l + 2b

= 36 + 28.5

= 64.5

Thus, perimeter of the rectangle is 64.5 meters
