Answer:
y = 8.13 x -16125.713
hope it helps
Step-by-step explanation:
Sum of X = 14004
Sum of Y = 977
Mean X = 2000.5714
Mean Y = 139.5714
Sum of squares (SSX) = 53.7143
Sum of products (SP) = 436.7143
Regression Equation = ŷ = bX + a
b = SP/SSX = 436.71/53.71 = 8.13032
a = MY - bMX = 139.57 - (8.13*2000.57) = -16125.71277
ŷ = 8.13032X - 16125.71277
Answer:
1)
2)
Step-by-step explanation:
Assuming that our function is for the first case and for the second case.
Part 1
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition
And the final solution would be:
Part 2
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition
And the final solution would be:
Answer:
20,114 mi/h
Step-by-step explanation:
It can be convenient to remember that 1 mi/h = 22/15 ft/s. To convert the given number to the appropriate units, we can divide by this conversion factor:
(29500 ft/s)/((22/15 ft/s)/(1 mi/h)) = (29500·15/22) mi/h = 20113 7/11 mi/h
≈ 20,114 mi/h
