Answer:
it is A
Step-by-step explanation:
you need to distribute the terms 
and -4 into their respective parentheses.
so the left side completed is 
next do the other side
(remember - * - = +)
Right side complete is
both put together is 
combine like terms to get
The answer is 15 seconds .
1/20 is a tiny portion of the length that needs to be traveled. 20/20 is the whole length. If 1/20 gets traveled in 3/4 of a second, multiply 3/4 by 20 to see how long it takes to travel 20(1/20) which is equal to 1, the whole path.
20(3/4) = 15 seconds
Answer:
55/9
Step-by-step explanation:
As a rule of thumb, when each component is selected independently from the same population, the sampling distribution of the sample percentage may be estimated by a regular probability distribution.
<h2>Why is it crucial to use the thumb rule?</h2>
- One of our primary, simple-to-learn ways to handle complexity is the rule of thumb. Real thumb rules take into account operating, security, and financial constraints.
- They inform us of the likely location of a practical solution. Additionally, they reveal which tactics are most prone to failure.
<h3>What is sampling distribution?</h3>
- A statistic that is obtained by sampled data from a bigger population is known as a sampling distribution.
- It depicts an array of potential results that may result from a statistic, such as the mean or mode of a certain parameter because there is really a population.
Therefore the main solution is- from the identical group, each component is individually chosen.

Volume of the bottom cuboid = 5 x 6 x 3 = 90 ft³
Volume of the pyramid = 1/3 x 5 x 6 x 3 = 30 ft³
Total = 90 + 30 = 120 ft³
