Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13
For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.
Answer:
49 would be the answer
Step-by-step explanation:
7x9-14
7x9 = 63
63-14 = 49
Answer:
z=27
x=114
Step-by-step explanation:
6z-96 = 66
6z=162
z=27
180-x=66
x=114
Answer:
x = 20
Step-by-step explanation:
3x = 40 + x
-x -x
2x = 40
Divide both sides by 2
x = 40/2
x = 20
I hope this was helpful! <3
Could I get brainliest?
Hey, let's figure this out together. :)
The answer is 1 and 6. Now we can prove that is true.
1 x 6 = 6
1 + (6) = 7
Thanks for using Brainly. :)
