Answer:
Systematic Sampling
Step-by-step explanation:
Systematic sampling is one of the types of probability sampling method. It is an advanced form of simple random sampling. In this form, from the population of members, sample members are selected randomly. In this random selection, a starting point is fixed. The sample is created when the members are selected from the fixed intervals.
In the given excerpt, systematic sampling method has been used. Here, the sample has been created by selecting every third listed phone member. The interval has been created between in the sample size.

9x+2 (x-2) = 2 (3-x)
Alternate Forms:
13 x = 10
13 x - 10 = 0
11 x - 4 = -2 (x - 3)
Expandend Form:
11 x - 4 = 6 - 2 x
Solution:
x = 10/13
Answer:
I think the answer is -2x squared +19x-12. I hope that this helps:)

Fint the are and perimeter of the shape at the bottom
Answer:
Area: 59.5 ft squared
Perimeter: 31.6 feet
Step-by-step explanation:
Area:
For the area of the square, you're going to use the formula length times width. The length and width are both 7, so you'll do 7 times 7, which is 49. Next, you need to find the area of the triangle. It's a bit more confusing since they give you the hypotenuse (7.6 ft), but they did that to try and trick you. The area of a triangle is length times width divided by two. So, you're going to take the width (3) and multiply it by the length (7). The length is 7 because the length of the square and the triangle are the same since the bottom of the triangle is the same length as the top of the square. Anyway, using the formula, you will do 7 times 3 divided by 2, which is 21 divided by 2, which is 10.5. Add the 10.5 to the 49 we got from the square, and you'll get 59.5 feet squared.
Perimeter:
For the perimeter, you just need to add the side lengths. Starting at the top and going to the right, we can add 7.6+7+7. We don't get the left length, but it's the same as the rest of the square (7) because all sides of a square are equal. So, now we have 7.6+7+7+7, which is 28.6, and we just need the last one which is 3, so the final answer is 31.6 feet.
Answer:
Area: 59.5 ft squared
Perimeter: 31.6 feet
Step-by-step explanation:

Michael can mow 5 lawns in 36 minutes. At this rate, how long will it take him to mow 15 lawns?
Answer:
It would take him 108 minutes to mow the lawn.
Step-by-step explanation:
We can do proportion.
[tex] \frac{5 \: lawns}{36 \: minutes} = \: \frac{15 \: lawns}{x} [/tex]
[tex]36 \times 15 = 540 \\ 5 \times x = 5x[/tex]
[tex] \frac{540}{5} = \frac{5x}{5} [/tex]
[tex]108 = x[/tex]
