Answer:
below given!
Step-by-step explanation:
1) mean = (7.4 + 5.8 + 7.3 + 7 + 8.9 + 9.4 + 8.3 + 9.3 + 6.9 + 7.5 + 9 + 5.8 + 5.5 + 8.6 + 9.3 +3.8) / 16
mean = 7.47
1. y₁ = 70x
2. y₂ = 55x
Solve y₁ - y₂ for x = 11.
18% of 40 is 7.2
Change the percentage (18%) into a decimal by dividing it over 100:
18/100 = 0.18
Divide 7.2 by the decimal (0.18):
7.2 / 0.18 = 40
