Answers

Answer 1

Answer:

B) 55cm

Step-by-step explanation:

Circumference = πd

                         = [tex]\frac{22}{7}[/tex] x [tex]\frac{35}{2}[/tex]

                         = 55cm

Answers

Answer:

Length = 13 in

Width = 10 in

Step-by-step explanation:

Let L be the length.

Let W be te width.

From the question given above, the Lenght is 3 more that the width i.e

L = 3 + W

Next, we shall determine the width (W). This can be obtained as follow:

Length (L) = 3 + W

Width (W) = W

Area (A) = 130 in²

A = L × W

130 = (3 + W) × W

Clear bracket

130 = 3W + W²

Rearrange

W² + 3W – 130 = 0

Solving by formula method

W = –b ± √(b² – 4ac) / 2a

a = 1

b = 3

c = –130

W = –3 ± √(3² – 4 × 1 × –130) / 2 × 1

W = –3 ± √(9 + 520) / 2

W = –3 ± √(529) / 2

W = –3 ± 23 / 2

W = –3 + 23 / 2 or –3 – 23 / 2

W = 20/2 or –26/2

W = 10 or –13

Since measurement can not be negative, the width is 10 in.

Finally, we shall determine the length. This can be obtained as follow:

L = 3 + W

W = 10

L = 3 + 10

L = 13 in

SUMMARY

Length = 13 in

Width = 10 in

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.
The relative frequency of the spinner landing on green is


The relative frequency of the spinner landing on blue is


The relative frequency of the spinner landing on yellow is


The relative frequency of the spinner landing on red is

Answers

Answer:

Step-by-step explanation:

The theoretical frequency would be 1/4, and if spun 60 times, 15/60.

The relative frequency is how many times it actually landed on each color.

So green is 6/60

Blue is 24/60

Yellow is 9/60

Red is 21/60

I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:

Green: 1/10

Blue: 4/10

Yellow: 3/20

Red: 7/20

Thanks to its monopoly position, Barnacle has earned more than $160 million over the past decade.

The annual (inverse) demand function for Barnacle's product is given by P-450 - 0.0003Q, and Barnacle's cost function is given by q) = 280Q. Thanks to subsidies stemming from an energy bill passed by Congress nearly two decades ago, Barnacle does not have any fixed costs: The federal government essentially pays for the plant and capital equipment required to make this energy-saving product. Absent this subsidy, Barnacle's fixed costs would be about $7 million annually. Knowing that the company's patent will soon expire.

Voluntary contributions toward a public good Susan and Becky are considering contributing toward the creation of a water fountain. Each can choose whether to contribute $300 to the water fountain or to keep that $300 for a cell phone. Since a water fountain is a public good, both Susan and Becky will benefit from any contributions made by the other person. Specifically, every dollar that elther one of them contributes will bring each of them $0.90 of benefit. For example, if both Susan and Becky choose to contribute, then a total of 5600 would be contributed to the water fountain. So, Susan and Becky would each receive $540 of benefit from the water fountain, and their combined benefit would be $1,080. This is shown in the upper left cell of the first table. Since a cell phone is a private good, If Susan chooses to spend $300 on a cell phone, Susan would get $300 of benefit from the cell phone and Becky wouldn't receive any benefit from Susan's choice. If Susan still spends $300 on a cell phone and Becky chooses to contribute $300 to the water fountain, Susan would still receive the $270 of benefit from Becky's generosity. In other words, If Susan decides to keep the $300 for a cell phone and Becky decides to contribute the $300 to the public project, then Susan would receive a total benefit of $300 + $270 = $570, Becky would receive a total benefit of $270, and their combined benefit would be s840. This is shown in the lower left cell of the first table. Complete the following table, which shows the combined benefits of Susan and Becky as previously described. Becky Doesn't contribute S Contributes $1,000 $840 Contributes Doesn't contribute Susan of the four cells of the table, which gives the greatest combined benefits to Susan and Becky? When both Susan and Becky contribute to the water fountain When neither Susan nor Becky contributes to the water fountain When Susan contributes to the water fountain and Becky doesn't, or vice versa of the four cells of the table, which gives the greatest combined benefits to Susan and Becky? O When both Susan and Becky contribute to the water fountain When neither Susan nor Becky contributes to the water fountain O When Susan contributes to the water fountain and Becky doesn't, or vice versa Now, consider the incentive facing Susan individually. The following table looks similar to the previous one, but this time, it is partially completed with the individual benefit data for Susan. As shown previously, if both Susan and Becky contribute to a public good, Susan receives a benefit of $540. On the other hand, if Becky contributes to the water fountain and Susan does not, Susan receives a benefit of $570. Complete the right-hand column of the following table, which shows the individual benefits of Susan. Hint: You are not required to consider the benefit of Becky. Becky Doesn't contribute Contribute $540, -- Contribute $ Susan Doesn't contribute $570, -- If Becky decides to contribute to the water fountain, Susan would maximize her benefit by choosing the other hand, if Becky decides not to contribute to the water fountain, Susan would maximize her benefit by choosing to the water fountain. On to the water fountain. These results illustrate Doesn't contri the free-rider problem to the water fountain.
