65-20 = 45
45/.75 = 60 miles
I hope this isn't to vague
Answer:
(2×2000)+(2×500)+(2×40)+(2×6)
Answer:
Option B. Quadratic
Step-by-step explanation:
In a regression model, the value of tells us how accurately the model fits the data.
That closer the value of of 1 is, better is the model.
This can be used to compare what type of model is most convenient to use in some cases.
In this problem the attached table shows a comparison of the value of for 3 models
Linear
Quadratic
Exponential
Note that the value of that is closest to 1 is that which corresponds to the quadratic model.
Therefore the function that best fits the points is the quadratic
Answer:
They did not flip the inequality
Step-by-step explanation:
-x/4 < (x+2)/3
Multiply each side by 3
-3x<4x+8
Subtract 4x from each side
-3x-4x <4x-4x +8
-3x-4x<8
Combine like terms
-7x<8
Divide by -7. Remember to flip the inequality
-7x/-7 > 8/-7
x > -8/7
