Answers

Answer 1

Answer:

Answer: Cluster sampling

Step-by-step explanation:

A cluster sampling is a kind of random sampling technique in which the researcher splits the whole population into distinct sets known as clusters.

After that, he choose a random sample of clusters from the population and do analysis on it.

In the given situation, the objective of survey : "To determine customer opinion of their pricing:".

He first divides the number of check out lines according to weeks and randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. .

(Here , check out lines = clusters )

Therefore , the type of sampling is used = Cluster sampling

Five more than seven times a number is ninety-six. What is the number?Type an equation and solve

Answers

Answer: the answer to this problem is 13!

Step-by-step explanation: To solve this problem, we must work backward. So the last step we did in this problem was adding five to the number, so to work backward we must subtract 5 from 96 to get 91. Now then the last step was to multiply by seven and since we are working backward, we must divide by seven to get our original number 13.

This is the equation: (13*7)+5

Ted is constructing an equilateral triangle. He draws a segment with his straightedge and labels the endpoints A and B. He then puts the compass point on A, opens the compass until the pencil point is on B, and draws a circle.Which move is a correct next step for Ted?

Keep the same compass opening, place the compass point on B, and draw a circle.

Shorten the compass opening, place the compass point on B, and draw two arcs that intersect the circle.

Keep the same compass opening, place the compass at the midpoint of the segment, and draw a circle.

Widen the compass opening, place the compass point on B, and draw a circle.

Answers

Final answer:

To construct an equilateral triangle, Ted should maintain the same compass opening and draw another circle from point B. The intersection point of these two circles will form the third point of the equilateral triangle.

Explanation:

To construct an equilateral triangle, the correct next step for Ted, after drawing a circle with compass point on A and reaching B, would be to keep the same compass opening, place the compass point now on point B, and draw another circle. Where this second circle intersects with the first one, that will be the third point of the equilateral triangle.

This is because in an equilateral triangle, all the sides are of the same length. So, keeping the compass opening the same ensures that the distance from A to B is equal to the distance from B to the new point, and hence you get an equilateral triangle.

At Noise Pollution Cellular, plan A is $30.00 per month and $5.00 for every gigabyte of data. Plan B is $50.00 per month and $2.00 for every gigabyte of data used. Irfan wants to find out which plan is the best choice for him. On average, he uses five to eight GB of data per month.How much data would Irfan need to use for both plans to cost the same?

Answers

Answer:

Part 1) The best choice is Plan A

Part 2) The data is $6(2)/(3)\ GB$

Step-by-step explanation:

Part 1)

Let

y ----> the cost per month

x ----> the number of GB of data per month

we know that

Plan A

$y=5x+30$

Plan B

$y=2x+50$

Find out which plan is the best choice if he uses five to eight GB of data per month

Plan A

For x=5 GB -----> y=5(5)+30=$55

For x=8 GB -----> y=5(8)+30=$70

with Plan A the cost is between $55 and $70 -----> average $62.5

Plan B

For x=5 GB -----> y=2(5)+50=$60

For x=8 GB -----> y=2(8)+50=$66

with Plan B the cost is between $60 and $66 ----> average $63

therefore

The best choice is Plan A

Part 2) How much data would Irfan need to use for both plans to cost the same?

we have

y=5x+30 ----> equation A

y=2x+50 ----> equation B

Solve the system of equations by elimination

Subtract equation B from equation A

0=5x-2x+30-50

0=3x-20

3x=20

$x=(20)/(3)\ GB$

Convert to mixed number

$x=6(2)/(3)\ GB$ ----> for this data the cost is the same in both plans
