75 1/3 = 75.33
75.33% = 75.33/100
= 7533/10000
not sure if it can be simplified more than this
mean = sum/n
mean = (5 + 7 + 7 + 9 + 12 + 16 + 21)/7
mean = 77/7
mean = 11
Answer:
4
Step-by-step explanation:
y = 4*x
y = 4*1.5 = 6
y = 4*2.25 = 9
y = 4* 3.25 = 13
8 as that means what two of the same number makes up , in this case 64. 8x8=64
Angle D is 60° because it is a supplementary angle, meaning 180 (straight line) - 120 (angle A) = 60°
