.58. Absolute value gets rid of negative.
Answer:
160 cm
Step-by-step explanation:
Substitute x = 13 into the equation
y = 6.5(13) + 75.5 = 84.5 + 75.5 = 160
The median height of boys age 13 is 160 cm
Q = (c + d) / 2.....when d = 5 and Q = 21
21 = (c + 5) / 2 ...multiply both sides by 2
2 * 21 = c + 5
42 = c + 5
42 - 5 = c
37 = c <== answer A
Answer:
