Here are the data: Elementary Middle Secondary 17 17 10 15 12 12 20 10 14 12 8 16 14 5 18 15 20 10 What test should she conduct to determine if there is a difference among the levels

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

9 x 8 divided by (5-3)=36

answer: 193

explanation:

200-7 = 193
