In the data set shown below, what is the value of the quartiles?

{42, 43, 44, 44, 48, 49, 50}

A.Q1 = 43.5; Q2 = 44; Q3 = 49

B.Q1 = 43; Q2 = 44; Q3 = 48.5

C.Q1 = 43.5; Q2 = 44; Q3 = 48.5

D.Q1 = 43; Q2 = 44; Q3 = 49

Step-by-step explanation:

11 feet 6 inches and 8 feet 6 inches

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
