(I estimated the line to be 1.5 inches. Measure the line IRL so I can adjust the answer)

15. D.

16. B.

17. A.

Step-by-step explanation:

4. Rearrange the numbers; 44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56

Minimum = 44

First Quartile = 46

Median = 50

Third Quartile = 55

Maximum = 56

14. 12 × 8 = 96. 96 × 1.5 = 144

144/1 ÷ 15/4 = 144/1 × 4/15 = 576/15 = 38.4

15. 35(2) + [ -1/2(15) ] = 35(2) - 1/2(15)

16. The new numbers for 540 students are

8/60 = 72/540 Walked: 72

7/60 = 63/540 Car: 63

3/60 = 27/540 Bicycle: 3

42/60 = 378/540 Bus: 378

17. 280 × 9 = 2,520

Increase by 25% = 125% of the total

2,520 × 1.25 = 3,150

3,114 - 3,150 = -36
