Answer:
the first one and the third and the fourth
Step-by-step explanation:
The formula for volume is V=lhw, or length times height times weight. To find the length, you divide the volume by the height and width.
In this case, divide 3,060 first by 12, the height, then by 15, the width.
3,060/12=255
255/15=17
The length is 17.
Answer:

Step-by-step explanation:

Expand:


Subtract 8x from both sides:


Cube root both sides:
![\sqrt[3]{x^3} =\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E3%7D%20%3D%5Csqrt%5B3%5D%7B8%7D)

Answer:
Option B) Y - estimated average predicted value, X – predictor, Y-intercept (
), slope (
)
Step-by-step explanation:
In the simple linear regression model estimate is given by:

Comparing this regression line with the slope intercept form, we get:

where m is the slope of the straight line and c is the y-intercept that is the value of y when x is zero.
here,
Y is the predicted variable or the variable we need to predict
X is the predictor or the variable that helps us to predict Y
is the slope of the regression line.
is the y-intercept or the value of y when x is zero.
Thus, Option B)
Y - estimated average predicted value, X – predictor, Y-intercept (
), slope (
)
