The given expression is:
4 - 8 (3/4) + 1/4
To start, we will convert all the numbers to be having a denominator of 4 as follows:
4 is equivalent to 16/4
-8 (3/4) is equivalent to -24/4
1/4 already has 4 as a denominator
Now, the new expression became:
16/4 - 24/4 + 1/4
Since they all have a common denominator, the result can be computed by adding numerators as follows:
16/4 - 24/4 + 1/4
= (16-24+1) / 4
= -7/4
The correct choice is:
A. -7/4
You can add the length of the sides to find the perimeter.
8 + 8 + 7 + 12 = 35 inches
The volume of a Cube/Rectangular Prism is Length times Width times Height, (or for short L*w*h).
For a cube, the length, width, and height are equal. So the volume of a cube is L*L*L
In the question it says that the you know the length of one of the cubes sides, which is (x + 5).
So L = (x + 5).
So, the unsimplified expression is:
L * L * L
= (x + 5) (x + 5) (x + 5)
= (x^2 + 10x + 25)(x + 5)
= x^3 + 10x^2 + 25x + 5x^2 + 50x + 125
= x^3 + 15x^2 + 75x + 125
Answer:=Answer1 has the regression analysis with all 4 independent variables. Using the stepwise method, we toss the one with the largest non-significant p-value which is Senior Present. Then do another regression analysis with only 3 independent variables. Answer2 has this. From this analysis we can toss education (has the largest non-significant p-value) and do another analysis which is in Answer3. In this analysis we see that Income is not quite significant (p=.0586) at the 0.05 level so we can toss it and do an analysis with Family Size as the only independent variable. This result is given in Answer4. The final regression equation has Family Size as the only independent variable and it can stay in the regression equation because it is statistically significant (p=.0003). The prediction equation is given at the bottom of Answer4. This should answer your question. If not let me know.
