Answer:
Max's paper airplane flew 
feet or 
feet.
Step-by-step explanation:
As Nora's paper airplane flew 9 1/6 feet
i.e.
Nora's paper was farther than Max's plane flew by = 2 3/4 feet
i.e.
Thus the equation to show how far Max's paper airplane flew is:
Therefore, Max's paper airplane flew feet or feet.
Mean a=75/10, mean b=73/10............about the same
range a=2-10=8, range b=4-12=8.........about the same
Answer:
aₙ = -15 + 10 * (n-1)
Step-by-step explanation:
aₙ = a₁ + (n-1)*d a₁: first term d: common difference
a₅ a₁ + 4d =25 .... (1)
a₁₁ a₁ + 10d = 85 ...(2)
(2) - (1) 6d = 60
d = 10
a₁ = -15
Formula: aₙ = -15 + 10 * (n-1)
