The volume of the rectangular solid is: 11,960 units³.
<h3>How to Find the Volume of a Rectangular Solid?</h3>
The formula to find the volume of a rectangular solid is: (length)(width)(height).
Given the dimensions as:
- Length = 20 units
- Width = 23 units
- Height = 26 units
Volume = (20)(23)(26)
Volume of the rectangular solid = 11,960 units³.

To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.

-4x +4 = -3x + 31
4 - 31 = -3x + 4x
-27 = x
Answer:
Step-by-step explanation:
A.
R(x)=px=x(-45 x+1800)=-45 x²+1800 x
B.
C(x)=7000+100 x
C.
P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)
or P(x)=-45x²+1800 x-100 x-7000
or P(x)=-45 x²+1700 x-7000
