Answer:

x=9

Step-by-step explanation:

First, distribute the 2 and each value in the parentheses.

2*x+2*5. This is the first half of the equation.

2*x+2*5= 3x+1 You can then simplify

2x+10=3x+1 Subtract 3x from both sides

(2x-3x)+10=(3x-3x[cancels out])+1

-x+10=1 Now subtract 10 from both sides

-x(10-10[cancels out to 0])=(1-10)

-x=-9 Since x is negative we need to solve for positive

x=9

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.
