Answer:
see below
Step-by-step explanation:
Part 1: 5(2x - 4) = 30.
Distribute
10x -20 = 30
Add 20 to each side
10x-20+20 =30+20
10x = 50
Divide by 10
10x/10 = 50/10
x =5
Part 2: 5x + 3 - x + 2 = 41
Combine like terms
4x +5 = 41
Subtract 5 from each side
4x+5-5 = 41-5
4x = 36
Divide by 4
4x/4 = 36/4
x = 9
The answer is definitely B
Answer:
B
Step-by-step explanation:
I picked B. The frequency has 4 things from 0-4, 5 things from 5-9, 3 things from 10-14, and 2 things from 15-19. I counted them for you
Hope this helps please mark brainliest :D
77 - (-145) = 77 + 145 = 222
Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8
After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9
So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)
So it's C :The median increases less than the mean increases.
