The scores for all the sixth graders on a statewide test are normally distributed with the mean of 76 and a standard deviation of 10. What percent of students scored below 86 ?

 A. -14. x=-14 and -14=x. *The answer should be the negative sign.*

Step-by-step explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

switch sides of an equation.

x+19=5

subtract by 19 both sides of an equation.

x+19-19=5-19

simplify.

19-5=14

x=-14 and -14=x

Hope this helps!

Thanks!

Have a great day!
