A school district has 1,200 students entering the first grade. Each child is administered an irytelligence test that is known to have a mean of 100 and a standard deviation of 15. State guidelines

require that children scoring either above 125 or below 75 be enrolled in special enrichment

programs. How many children will the school district expect to enroll in the enrichment programs

for this group of first graders?

(A) 50 (B) 57 (C) 114 (D) 120 (E) 1085

answer:   y=2x-3

step-by-step explanation:

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
