Mean, median, and mode of 10, 5, 7, 6, 7, 5, 4, 12 and box and whiskers plot (5 marks)

Something about weighted mean, find % (4 marks)

Weight that is 1.5 standard deviation below the mean: To find the weight that is 1.5 standard deviation below the mean, subtract 1.5 times the population standard deviation from the population mean.

The population mean, population standard deviation, and weight that is 1.5 standard deviation below the mean for the Houston Rockets can be calculated using the following steps:

1) Population mean: The population mean is the average of all the values in the population. To calculate the population mean, add up all the values in the population and divide by the total number of values. For example, if the weights of the Houston Rockets players are 200, 210, 220, 230, and 240 pounds, the population mean would be (200 + 210 + 220 + 230 + 240) / 5 = 220 pounds.

2) Population standard deviation: The population standard deviation is a measure of how spread out the values in the population are. To calculate the population standard deviation, first calculate the deviation of each value from the population mean, square each deviation, add up all the squared deviations, divide by the total number of values, and take the square root of the result. For example, if the weights of the Houston Rockets players are 200, 210, 220, 230, and 240 pounds, the population standard deviation would be √[((200 - 220)^2 + (210 - 220)^2 + (220 - 220)^2 + (230 - 220)^2 + (240 - 220)^2) / 5] = 14.14 pounds.

3) Weight that is 1.5 standard deviation below the mean: To find the weight that is 1.5 standard deviation below the mean, subtract 1.5 times the population standard deviation from the population mean. For example, if the population mean is 220 pounds and the population standard deviation is 14.14 pounds, the weight that is 1.5 standard deviation below the mean would be 220 - (1.5 * 14.14) = 199.79 pounds.

The total cost of each utility eliminating 450 tons of pollution is $180,000.

To calculate the total cost for each utility to eliminate 450 tons of pollution, we need to multiply the cost per ton of pollution elimination by the number of tons each utility needs to eliminate.

For People's Electric, the cost of eliminating one ton of pollution is $400. So, to eliminate 450 tons, the total cost would be 450 tons * $400/ton = $180,000.

For Municipal Energy, the cost of eliminating one ton of pollution is $350. Again, to eliminate 450 tons, the total cost would be 450 tons * $350/ton = $157,500.

Therefore, the total cost for each utility to eliminate 450 tons of pollution is $180,000 for People's Electric and $157,500 for Municipal Energy.

The cost calculation is based on the given information that each utility is provided with 450 pollution permits by the government. These permits allow them to legally produce a ton of pollution. By setting a limit on the number of permits, the government aims to reduce pollution by half. The utilities have the option to trade permits with each other.

In this scenario, People's Electric has a higher cost of eliminating pollution per ton compared to Municipal Energy ($400 vs. $350). It means that People's Electric would find it more expensive to reduce pollution through internal measures like investing in cleaner technology or implementing environmental initiatives. On the other hand, Municipal Energy has a lower cost, indicating that they have relatively more cost-effective methods for pollution reduction.

Given these costs, it is more beneficial for People's Electric to purchase permits from Municipal Energy rather than eliminating the pollution themselves. By purchasing permits, People's Electric can meet the pollution reduction target at a lower cost. Conversely, Municipal Energy can generate additional revenue by selling their permits.

This permit trading mechanism allows for cost efficiency in achieving the government's pollution reduction goal. The total cost for each utility is determined by multiplying the cost per ton of pollution elimination with the number of tons they need to eliminate.

The F-distribution is used to test the significance of the population coefficient of determination (option D).

The coefficient of determination, denoted as R², measures the proportion of the variance in the dependent variable that is explained by the independent variables in a regression model. It ranges from 0 to 1, where 0 indicates no relationship and 1 indicates a perfect relationship.

To determine the significance of R², the F-distribution is used. The F-test compares the variation explained by the regression model (numerator) to the unexplained or residual variation (denominator). It calculates the F-statistic, which is the ratio of the two variances.

The F-distribution provides critical values that allow us to determine whether the observed F-statistic is statistically significant or not. By comparing the calculated F-value with the critical value from the F-distribution, we can assess whether the coefficient of determination is significantly different from zero, indicating the presence of a meaningful relationship between the variables. The correct option is d.

To determine the number of suppliers Witt Input Devices should use, we need to consider the probability of a "super-event" and the marginal cost of managing additional suppliers.

With a 3% probability of a total shutdown and an estimated cost of $400,000, along with a 5% "unique-event" risk per supplier, the company should aim to balance the costs and risks to make an informed decision on the number of suppliers.

Phillip Witt wants to create a portfolio of local suppliers for his keyboards. He faces the risk of "super-events" that could shut down all suppliers simultaneously for at least two weeks. The probability of such an event occurring is 3% per year, which would result in an estimated cost of $400,000 for the company.

Additionally, each individual supplier carries a "unique-event" risk of 5%. To mitigate the risks, Witt Input Devices needs to determine the optimal number of suppliers to use. However, it is stated that up to three nearly identical local suppliers are available.

To make a decision, the company needs to balance the costs and risks. Each additional supplier incurs a marginal cost of $15,000 per year. The company should evaluate the trade-off between the cost of managing additional suppliers and the risk reduction achieved by having multiple suppliers.

Considering these factors, Witt Input Devices should analyze the costs and benefits of each additional supplier and select the number of suppliers that provides an optimal balance between risk mitigation and cost management.

Step-by-step explanation:

As a Decimal, 52% would be .52  

All you have to do to get that, is to move the decimal over twice.

So as a fraction, you would put 100 as the denominator because 100 is how high a percent can get.

The density of the Geometry textbook is 0.06 g/cm^3.

To find the density of the Geometry textbook in g/cm^3, we need to find its volume first. The volume of a rectangular prism is given by the formula V = l x w x h, where l is the length, w is the width, and h is the height.

In this case, the length is 16 cm, the width is 10 cm, and the height is 5 cm. Therefore, the volume of the Geometry textbook is:

V = l x w x h = 16 cm x 10 cm x 5 cm = 800 cm^3

Now, we can find the density of the textbook using the formula:

\(density = mass / volume\)

Plugging in the given mass of 48 grams and the calculated volume of 800 cm^3, we get:

density = 48 g / 800 cm^3 = 0.06 g/cm^3

Therefore, the density of the Geometry textbook is 0.06 g/cm^3. We rounded our answer to two decimal places as the original mass was given in grams to two decimal places.

The two non negative real numbers with a sum of 64 that have the largest possible​ product are; 32 and 32.

Let the two numbers be x and y.

Thus, if their sum is 64, then we have;

x + y = 64

y = 64 - x

Their product will be;

P = xy

Putting (64 - x) for y in the product equation we have;

P = (64 - x)x

P = 64x - x²

Since the product is maximum, let us find the derivative;

P'(x) = 64 - 2x

At P'(x) = 0, we have;

64 - 2x = 0

2x = 64

x = 64/2

x = 32

Thus; y = 64 - 32

y = 32

The area of the surface is 2π(3√3 - 1). The surface area integral is given by A = ∬D √(1 + (dz/dx)² + (dz/dy)²) dA.

To find the area of the surface that lies within the cylinder x² + y² = 64 and is defined by z = xy, we can use the surface area integral.

The surface area integral is given by:

A = ∬D √(1 + (dz/dx)² + (dz/dy)²) dA

where D represents the region on the xy-plane that corresponds to the surface.

In this case, the region D is the circle with radius 8 (which is obtained by solving x² + y² = 64). To evaluate the integral, we need to determine the partial derivatives dz/dx and dz/dy.

Taking the partial derivative of z with respect to x:

∂z/∂x = y

Taking the partial derivative of z with respect to y:

∂z/∂y = x

Substituting these values into the surface area integral formula:

A = ∬D √(1 + y² + x²) dA

Since D is a circle with radius 8, we can express the integral in polar coordinates. The limits of integration for r are 0 to 8, and the limits of integration for θ are 0 to 2π.

A = ∫₀²π ∫₀⁸ √(1 + r²sin²θ + r²cos²θ) r dr dθ

Simplifying the expression under the square root:

A = ∫₀²π ∫₀⁸ √(1 + r²) r dr dθ

Now we can evaluate the integral:

A = ∫₀²π [(1/3)(1 + r²)^(3/2)]⁸₀ dθ

A = ∫₀²π (1/3)(9√3 - 1) dθ

A = (1/3)(9√3 - 1) ∫₀²π dθ

A = (1/3)(9√3 - 1)(2π - 0)

A = 2π(3√3 - 1)

The area of the surface is 2π(3√3 - 1).

Step-by-step explanation:

The number of pounds of cashews that cost $14 per pound that must be mixed with 5 pounds of peanuts that cost $6.50 per pound to make mixed nuts that cost $10.25 per pounds is 5 pounds.

The expression above forms the equations below:

14 × x  + 5 × 6.50 = (x + 5) × 10.25

where

Therefore,

14 × x  + 5 × 6.50 = (x + 5) × 10.25

14x + 5 × 6.50  =  (x + 5) × 10.25

14x + 32.5 =  (x + 5) × 10.25

14x + 32.5 = 10.25x + 51.25

subtract 10.25x from both sides

14x + 32.5 = 10.25x + 51.25

14x  - 10.25x + 32.5 = 10.25x - 10.25x + 51.25

3.75x + 32.5 = 51.25

subtract 32.5 from both sides

3.75x + 32.5 = 51.25

3.75x + 32.5 - 32.5 = 51.25 - 32.5

3.75x = 18.75

divide both sides by 3.75

3.75x = 18.75

3.75x / 3.75 = 18.75 / 3.75

x = 5

Therefore, the number of pounds of cashews that cost $14 per pound that must be mixed with 5 pounds of peanuts that cost $6.50 per pound to make mixed nuts that cost $10.25 per pounds is 5 pounds.

Step-by-step explanation:

Please find the complete question:

The dilation scale factor will be the same:

\(=\frac{\text{Picture to Center Gap}}{\text{Related pre-image distance to the middle}}\)

Throughout the picture, the distance is \(CP'=6\), while the equivalent distance is \(CP=14\). The factor of scale is then\(=\frac{CP'}{CP} =\frac{6}{14} =\frac{3}{7}\)

The decrease because if a factor of scale is below 1 and a factor of scale is higher than 1. Dilation is a reduction since \(\frac{3}{7}<1\), therefore the scale factor is \(\frac{3}{7}\).

The scale factor of the given dilation is; 6/14 and the dilation is a reduction

The image of the object undergoing transformation is missing and so i have attached it.

From the attached object, we se that CP = 14.

3600 in. is equal to 25 square feet, calculated using two unit multipliers.

To convert 3600 in. to square feet, there are two unit multipliers we can use: 1 ft/12 in and (1 ft/12 in)^2. Here's how to perform the conversion:

Multiply 3600 in. by 1 ft/12 in (the first multiplier) to convert inches to feet:

3600 in. × (1 ft/12 in) = 300 ft

Multiply 300 ft by (1 ft/12 in)^2 (the second multiplier) to convert square feet back to square inches:

300 ft × (1 ft/12 in)^2 = 3600 sq in.

Since you initially had 3600 sq in, which is equivalent to 25 sq ft (because 1 sq ft = 144 sq in), your final answer is:

3600 in. = 25 sq ft

Therefore, 3600 in. is equal to 25 square feet.

Answer:

The point is at about (4.5, 100).

Step-by-step explanation:

Minka's line is p = 22t, which has a y-intercept of 0.

Kenji's line is p = 50 + 11t, which has a y-intercept of 50.

Find the line with y-intercept at 0 and the line with y-intercept at 50. Follow the two lines until they intersect. The point of intersection is about (4.5, 100).

You can find this point by setting the two equations equal to each other:

22t = 50 + 11t

Subtract 11t from both sides.

11t = 50

t = 50/11 ≈ 4.545

Then you can find the p value for this point by plugging t = 4.545 into either equation.

p = 22(4.545) = 99.99

p = 50 + 11(4.545) = 99.995

On the graph the point is about (4.5, 100).
