What is the range of the following numbers? 12, 20, 18, 25.6​

13.6

Step-by-step explanation:

subtract the lowest number from the highest number to find the range. in this case, the data range is 25.6−12=13.6

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
