Answer:
d. slope; intercept
Step-by-step explanation:
A regression equation is represented in the form :
y = mx + c (linear regression)
Where y = predicted variable
m = slope of regression line
x = independent variable
c = intercept (where the regression line crosses the y axis).
For a multiple regression equation where there are more than one independent, then we have multiple slopes
y = c + m1x1 + m2x2 +...mnxn
Hence, the slope. And intercept are the two key part of a regression equation which enables us to make prediction and correlation about the dependent and independent variables.
Answer and Step-by-step explanation:
The answer is 54.
We see that each time, the number is being multiplied by 1.5.
54 times 1.5 = 81 * 1.5 = 108
54 times 2 = 108
<u>54 is the starting number, because when you multiply 54 by 1, you get 54 for y.</u>

Answer:
0.75 could be a 25% discount. 1.06 could be a sales tax.
Step-by-step explanation:
If p is the original price, then 1.06p could be the amount after a 6% tax is include. Then multiplying by 0.75 could indicate a 25% discount (if you <u>don't</u> pay 25% = 0.25, then you <u>do</u> pay 75% = 0.75).
In case you're wondering about discounting <u>first</u> then charging tax, the result is the same because the multiplication can be done in either order.
0.75(1.06p) = 1.06(0.75p)
