Answer:
Step-by-step explanation:
The given expression is
To factor this polynomial, we just need to extract the common factor. Or you can see as the greatest common factor.
What is the greatest common factor between 8 and 16?
16: 1, 2, 4, 8, 16.
8: 1, 2, 4, 8.
You can observe that the greatest common factor is 8, so we extract it from both numbers
Notice that we placed the GCM in the front as a product, if we don't do that, it would be completely wrong, because we can change the equivalence of the expression. Now, notice that each variable have different coefficients, that is because if you extract the GCM, you need to placed its quotients as coefficients.
Therefore, the factor of the polynomial is
400

The distribution of means is the correct comparison distribution when
Answer: The distribution of means is the correct comparison distribution when there is more than one person in a sample.
The distribution of the sample means is also called the sampling distribution of mean. It is most appropriate when we take a random sample of size n from the population of size N. The distribution of the sample means will follow normal distribution with mean = 
and standard deviation = 
Answer:
Step-by-step explanation:
The figure is made up of a rectangle and two semicircles.
We find the area of the rectangle using the formula;
We find the area of one of the semicircles and multiply by 2;
The area of the semicircles
We substitute 
and 
to obtain;
The area of the figure is
To the nearest tenth we have;
The correct answer is A
