The answer is 4
The answers is four because 10/3(aka 3 1/3) +2/3=(10 ×3)+ (2×3)/3×3=36/9= 36 ÷ 9/9÷9=4
so the answer is four

to find any probability just find the total and then divide that by the number of whatever you're checking for, eg. parkour backgrounds.
A)
7+3+4+6 = 20 total backgrounds
6 parkour backgrounds.
20/6 is your answer.
B)
6 + 10 + 5 = 21 total marbles
10 + 6 = 16 non yellow marbles
21/16 is your answer.
C)
6 + 10 + 5 = 21 total marbles
10 blue marbles
21/10 or 2.1 is your answer.
The answer would be the median because you use the box plot to find the median. its the whole point of a box plot :)
Answer:
4 liters of 5% and 16 liters of 17.5%
Step-by-step explanation:
Let quantity of 5% be x liters and of 17.5% be y liters
x+y=20 hence y=20-x
Introducing percentages
0.05x+0.175(20-x)=0.15*20
0.05x+3.5-0.175x=3
-0.125x=-0.5

Therefore, y=20-x=20-4=16
You need 4 liters of 5% and 16 liters of 17.5% to achieve 20 liters of 15% acid solution
