Answer: (3,4)

multiply both sides of the top equation by 2

get rid of the x variable by subtracting add all corresponding numbers and variables (4+(-4), -4+7, -4+16) which leaves you with 3y=12

divide both sides by 3 which cancels out the 3y and leaves you with y=4

input y in your top equation to find x. (-2x+2x4=2)

this leaves you with x=3

I HOPE THAT MADE SENSE!!!

The equation would be worded as: 2m+16=36.


Solve! Using the subtraction property of equality, 2m=20. Then the division property of equality lets us figure out that m=10.

NEEEEEEDDDDD HELP ASAP

The correct answer is that there is more variability in the heights of the volleyball team members.

The mean absolute deviation shows us how spread out the data is, so the larger the mean absolute deviation the higher the variability.

Both teams have players that are 76 inches tall, so the last two statements cannot be true.

Help and explain how you got it.<br><br> no trolling or report!

Answer:

I am 100% confident in my calculations. I'm not 100% sure about interpreting. Sorry I can't be of more help.

Part A:

Median: 4.5

IQR: 3.5

Mode: 6

I think the median/IQR is a better measure of center and variability because the range of data is so big (10 - 0 = 10), and the data skews to the right with the 6s.

Part B:

I would say no. It is the one that occurs most frequently, but there are many more times she rides less than 6, which is why the median is 4.5

Step-by-step explanation:

Mean: 4.714

MAD: 2.43

Median: 4.5

IQR: 3.5

Mode: 6

the number set in order:

0, 2, 2, 2.5, 2.5, 3, 4, 5, 6, 6, 6, 8, 9, 10

The median (middle number) is two numbers: 4 and 5, so the median is 4.5

The first quartile/Q1 (middle of the bottom half of data) is 2.5, the third quartile/Q3 (middle of the top half of data) is 6. So the IQR (interquartile range) is 6 - 2.5 = 3.5

The mean is the sum of the numbers divided by the quantity of the numbers, so 66/14 = 4.714

the mean absolute deviation is found by calculating the mean, and then finding the absolute value of the difference between each number of the set and the mean...then adding those together and finding the mean of that set. Labor intensive, but that's 34/14 = 2.42857143
