Can someone please answer this question please answer it correctly and please show work please help me please help

4. A.

14. A. 38.4 mph

(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

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
