It would take Samantha 40 minutes to run 5 miles!!!
Total number of marble = 10
3green
2red
5 blue
Probability that the first marble is red = 2/10
Probability that the second is blue = 5/9(a reduction in the total number of marbles, because after the first marble was picked it wasn't replaced)
Probability of 1st and 2nd being red and blue respectively = 2/10 × 5/9
=1/9....
Hope this helped...?
Mean is the average of all numbers
(5+2+7+8+2+5+3)/7
Mean is 4.57
Median is the middle score so we have to arrange all the numbers from lowest to highest
2, 2, 3, 5, 5, 7, 8
Median is 5

Simplifying
3m + 5 = 4m -10
Reorder the terms:
5 + 3m = 4m -10
Reorder the terms:
5 + 3m = -10 + 4m
Solving
5 + 3m = -10 + 4m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-4m' to each side of the equation.
5 + 3m + -4m = -10 + 4m + -4m
Combine like terms: 3m + -4m = -1m
5 + -1m = -10 + 4m + -4m
Combine like terms: 4m + -4m = 0
5 + -1m = -10 + 0
5 + -1m = -10
Add '-5' to each side of the equation.
5 + -5 + -1m = -10 + -5
Combine like terms: 5 + -5 = 0
0 + -1m = -10 + -5
-1m = -10 + -5
Combine like terms: -10 + -5 = -15
-1m = -15
Divide each side by '-1'.
m = 15
Simplifying
m = 15
