The given graph starts from down to up and forms a straight line. Thefor, the correlation coefficient that best matches the data plotted on the graph is 0.90.
Answer:
34.65 is less than 34.7
34.65 < 34.7
The larger (open) side goes next to the bigger number.
Answer:
342.5 miles or D
Step-by-step explanation:
55 x 3.5 = 192.5
60 x 2.5 = 150
192.5 + 150 = 342.5
This should be it! Please mark me Brainliest :)
For this case we have the following function:
f (t) = -16t2 + 32t + 384
By definition we have to:
The average rate of change:
AVR = (f (t2) - f (t1)) / (t2 - t1)
Where,
For t1 = 4
f (4) = -16 * (4) ^ 2 + 32 * (4) + 384
f (4) = 256
For t2 = 6
f (6) = -16 * (6) ^ 2 + 32 * (6) + 384
f (6) = 0
Substituting values we have:
AVR = (0 - 256) / (6 - 4)
AVR = -128
Answer:
The average rate of change of f (t) from t = 4 seconds to t = 6 seconds is -128 feet per second.
