Answer:

If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.

Two cyclists, 96 miles apart, start riding toward each other at the same time. One cycles 3 times as fast as the other. If they

<span>18 mph. OK. Let's call the speed of the slower cyclist X, And since the faster cyclist is 3 times faster, that speed will be 3X. So their combine closing speed will be (X + 3X) and over a period of 4 hours, they travel 96 miles. So the equation becomes: 4(X + 3X) = 96 Now solve for X 4(X + 3X) = 96 4(4X) = 96 16X = 96 X = 6 So the slower cyclist has a speed of 6 mph. And since the faster cyclist is 3 times faster, that speed is 3*6 = 18 mph.</span>

If the sampled population is finite and at least _____ times larger than the sample size, we treat the population as infinite.

Marta_Voda [28]

Answer:

The answer is "20".

Step-by-step explanation:

It is also known as the group of the study, that targets the population, which helps to find the survey, which is the sampled population. It is measured by an ideal world, which will be the same, and they're always unique.

Its sampling distribution of the "x bar" should also be naturally independent of the random sample, that is usually distributed.
We consider the population as endless if the sampling size is at least 20 times greater than the sample size.
