Answer:
Answer: 14
Step-by-step explanation:
14
interquartile range = upper quartile - lower quartile
first, order the scores from least to greatest
55, 58, 65, 66, 70, 72, 81
thus, UQ = 72 and LQ = 58
IQR = UQ - LQ = 72 - 58 = 14
What a coincidence that I just did this in my math class today. A function is a relation in which no 2 different ordered pairs have the same first coordinate. They are allowed to have the same second coordinate. So the third option is correct.
D option is your answer bro
8
probability of getting a 5 is 1/6 so you would do 1/6 x 48
48/6 = 8
