Answer:
b. $25
Step-by-step explanation:
64 + 25 + 37 - 52 - 49 = 25
D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.

The answer for the graph is x ≤ 5
Answer:
0.09 average effect
Step-by-step explanation:
Given that the t statistics = 1.54
Sample size (n) = 25
Therefore, variance = t²/n
Variance = 1.54²/25
Variance = 2.372/25
Variance = 0.09
