2 left-bracket (12 + 2 x) + (15 + 2 x) right-bracket = 74

The value of x is 2.5 or 5/2.

Step-by-step explanation:

First, you have to eliminate the inner brackets followed by the outer bracket :

Next you have to solve it :

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
