In one sample t-test, you compare it to some value that you already know to represent the population mean. In the t-test for correlated groups, the statistic is the difference between your two samples, which you test against the population mean difference.
Answer:
The best is f(x) = (x + 3)(x − 3)(x + 1).
Step-by-step explanation:
The coefficient of x^3 will be positive because of where the graph rises and falls.
As one of the x intercepts is negative 3 one of the factors will be (x + 3).
By the same reasoning the other 2 factors will be (x - 3) and (x + 1).
(Volume for a rectangular shape is length x width x height)
We can split up this 3D composite figure into two main parts (as shown in the picture I attached), and find each part’s volume before adding them together for the total volume.
Cube —> 5x5x5 —> 25x5 = 125 in^3
Rectangular Prism —> 20x5x5 —> 100x5 = 500 in^3
125 + 500 = 625
So the answer is A. 625 in^3
