I'm not sure how much the monthly fee is, but assuming it's low, (150/22=6) she would be able to use the fitness club for 6 months.
Answer:
D. y = x - 3
Step-by-step explanation:
First, find the slope (m) of the line it is perpendicular to using the points of the line, (4, 2) and (-1, 7):
![slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 - 2}{-1 - 4} = \frac{5}{-5} = -1](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%3D%20%5Cfrac%7B7%20-%202%7D%7B-1%20-%204%7D%20%3D%20%5Cfrac%7B5%7D%7B-5%7D%20%3D%20-1%20)
Thus, the slope (m) of the line that is perpendicular to the line that runs through (4, 2) and (-1, 7) would be the negative reciprocal of -1.
The slope (m) if the line that is perpendicular to the other line = 1
Thus, substitute m = 1 and (a, b) = (1, -2) into y - b = m(x - a)
y - (-2) = 1(x - 1)
y + 2 = x - 1
Subtract 2 from both sides
y = x - 1 - 2
y = x - 3
325,000 is 324,650 rounded to the nearest thousand

• Systematic Sampling is a probability sampling method where people or researchers select members of the population in a regular interval.
• For example, by selecting every 17th person on the list of the population. If the population is in the random order, this can imitate the benefits of random sampling.
• Systematic sampling can help in minimizing biased samples and poor survey results. If there is a low risk for manipulation of data .
• Systematic sampling introduces certain arbitrary parameters in the data. This can cause overrepresentation or underrepresentation of patterns
In systematic sampling, members from a large population are selected according to a random starting and a fixed periodic interval.
Only stratified sampling, where the population is divided into several data, guarantees the member of each group within a population will be sampled.
