Answer:
For the first city, the 95% confidence interval would be:
28,900 +/- 2300 x 3 = 28,900 +/-6900$
For the second city, the 95% confidence interval would be:
30,300 +/- 2100 x 3 = 30,300 +/- 6300$
Don’t take my word for it but if there’s no x then it might be undefined.
Sorry if I’m incorrect
Answer:
base=5
height=3
Step-by-step explanation:
Answer:
A. 16 m
B. At t = 2 and t = 6
C. 8 seconds
Step-by-step explanation:
Maximum height is at the vertex
(4,16). So maximum height is 16 m at t = 4
The rocket is at a height of 12m at two distinct times:
At 2 seconds and again at 6 seconds
The rocket is in air when the height is not zero, I.e between t=0 and t=8
8-0 = 8 seconds
