Answers

The line plot is not symmetric because the numbers of siblings range from 0 to 8.

a. The line plot is not symmetric because the numbers of siblings range from 0 to 8. The number of students with 0 siblings is much greater than the number of students with 8 siblings.

b. The distribution is skewed left, meaning that the majority of students have fewer siblings than the average.

c. Since the distribution is skewed left, the median would be a better measure of the center because it is not affected by the outliers. The median number of siblings is 0. To measure the spread of the distribution, we can use the range, which is 8.

Therefore, the line plot is not symmetric because the numbers of siblings range from 0 to 8.

What is the appropriate measure of variability for the data shown, and what is its value?

The mean is the best measure of variability and equals 11.
The median is the best measure of variability and equals 11.5.
The range is the best measure of variability and equals 18.
The IQR is the best measure of variability and equals 2.

Answers

The appropriate measure of variability for this data set is the IQR, and its value is 2. The mean and median are measures of central tendency, not measures of variability. The range may not be the best measure of variability for this data set because it is influenced by extreme values.

The given data set is:

2, 10, 10, 12, 12, 20

To determine the appropriate measure of variability, we need to consider the spread or dispersion of the data. In this case, we can see that the range,

20 - 2 = 18.

A better measure of variability for this data set is the interquartile range (IQR), which is the range of the middle 50% of the data. To find the IQR, we first need to find the median of the data:

2, 10, 10, 12, 12, 20

The median is the middle value when the data set is arranged in order, which is 11. We can then divide the data set into two halves:

2, 10, 10 and 12, 12, 20

The lower half has a median of 10, and the upper half has a median of 12. The IQR is the difference between these medians:

IQR = 12 - 10 = 2

Therefore, the appropriate measure of variability for this data set is the IQR, and its value is 2. The mean and median are measures of central tendency, not measures of variability. The range may not be the best measure of variability for this data set because it is influenced by extreme values.

The bowling average of the players in the Capital Three bowling tournament is 158 with variance of 121. If Dr. Baker bowls an average of 169 during the tournament. Compute the appropriate statistic.

Answers

Answer: 1

Step-by-step explanation:

The formula for the Z-score is:

Z = (X - μ) / σ

where:

- X is Dr. Baker's bowling average

- μ is the mean bowling average of the players in the tournament

- σ is the standard deviation of the bowling averages of the players in the tournament

From the problem, we know that:

- μ = 158

- σ^2 = 121

- X = 169

Therefore, σ = sqrt(121) = 11.

Now we can plug in the values into the Z-score formula:

Z = (169 - 158) / 11 = 1

This means that Dr. Baker's bowling average is 1 standard deviation above the mean bowling average of the players in the tournament.

So the appropriate statistic is the Z-score, which is 1.

How to solve

To achieve equity between Equation A and Equation B, one must:

A: 4x + 1(x+4) = -3B: -12x - 48 = -12

Via combining 1 with the parenthesis of Equation A and conjoining common terms, one begins by distributing the 1 and fusing both sides together to form 5x + 4 = -3.

Afterward, multiplying both sides of the equation by -12 (the same non-zero constant), yields -60x - 48 = 36.

Ultimately, adding 72 to both equities presents the answer to furthering equations, -12x - 48 = -12.

Thus, the resolution rest in choice D- multiply/divide both sides by the same non-zero constant.

By producing Equation B from Equation A through analogous methods on either side of the equation, it is confirmed that the two compilations are equivalent and manifest exact solutions. Therefore, the proper selection for this query is Yes- Choice A.

Answers

The rectangular piece of paper has a perimeter of 48.34 units.

The perimeter of a rectangle is given by the sum of the lengths of all its sides.

To find the perimeter of this rectangular sheet of paper, we need to add up the lengths of its four sides.

The length of the rectangle is 12 + 1 by 2 = 13.5 units, and its width is 10 + 2 by 3 = 11.67 units.

Therefore, the perimeter of the rectangle is:

P = 2(length + width)

MODELING REAL LIFE The value of a mountain bike y (in dollars)
can be approximated by the model y 200(0.65)', where t is the
number of years since the bike was purchased. (See Example 2.)
=
a. Determine whether the model represents
exponential growth or exponential decay.
b. Identify the annual percent increase or decrease
in the value of the bike.
c. Estimate when the value of the bike will be $50.
C

Answers

The model y = 200(0.65)ⁿ represents exponential decay because the value of the bike decreases over time as t increases.

The value of the bike decreases by approximately 40.67% per year.

The value of the bike will be $50 approximately 5.2 years after it was purchased.

How to calculate the values

a. A = Peⁿ = 200e⁻⁰.⁴³⁰⁷≈ 118.66

The value of the bike after one year is approximately $118.66.

b. percent decrease = (initial amount - final amount) / initial amount * 100%

percent decrease = (200 - 118.66) / 200 * 100% ≈ 40.67%

c. We can set y = 50 in the model and solve for t:

50 = 200(0.65)ⁿ

0.65ⁿ = 0.25

Taking the natural logarithm of both sides, we get:

ln(0.65ⁿ) = ln(0.25)

t ln(0.65) = ln(0.25)

t = ln(0.25) / ln(0.65) ≈ 5.20

Part B: Prepare a reconciliation between the Governmental Fund Statement of Revenues, Expenditures, and Changes in Fund Balance and the Government-wide Statement of Activities for the year ending 12/31/22. Use proper headings and show any supporting computations

Answers

Answer:

governmental fund financial statements and government-wide financial statements have different purposes and accounting methods. Governmental fund financial statements focus on the short-term financial performance and accountability of individual funds, using the modified accrual basis of accounting. Government-wide financial statements provide a broader and longer-term perspective of the government's financial position and activities, using the full accrual basis of accounting.

To reconcile between these two types of statements, some adjustments are needed to account for the differences in measurement focus and basis of accounting. Here are the steps to prepare the reconciliations for Part A and Part B:

Part A: Reconciliation between the Governmental Fund Balance Sheet and the Government-wide Statement of Net Position at 12/31/22.

- Start with the total fund balance of the governmental funds as reported in the fund balance sheet ($200,000).

- Add the net value of capital assets (acquisition value minus accumulated depreciation) as reported in the government-wide statement of net position. This is because capital assets are not reported in governmental fund financial statements, but are reported in government-wide financial statements. The net value of capital assets can be calculated as follows:

- Acquisition value of capital assets as of 1/1/22: $10,000,000

- Plus: Purchases of capital assets during 2022: $1,000,000

- Less: Sales of capital assets during 2022: $30,000

- Equals: Acquisition value of capital assets as of 12/31/22: $10,970,000

- Less: Accumulated depreciation as of 1/1/22: $5,200,000

- Less: Depreciation expense for 2022: $500,000

- Equals: Accumulated depreciation as of 12/31/22: $5,700,000

- Net value of capital assets as of 12/31/22: $5,270,000

- Subtract the amount of bonds payable as reported in the government-wide statement of net position. This is because bonds payable are not reported in governmental fund financial statements, but are reported in government-wide financial statements. The amount of bonds payable can be calculated as follows:

- Bonds payable as of 1/1/22: $3,200,000

- Plus: Issuance of bonds payable during 2022: $400,000

- Less: Repayment of bonds payable during 2022: $200,000

- Bonds payable as of 12/31/22: $3,400,000

- Subtract the amount of accrued interest payable on long-term debt as reported in the government-wide statement of net position. This is because accrued interest payable is not reported in governmental fund financial statements, but are reported in government-wide financial statements. The amount of accrued interest payable is given as $180,000.

- Add the amount of property taxes receivable that are not available to pay current liabilities as reported in the governmental fund balance sheet. This is because property taxes receivable that are not available are not recognized as revenues in governmental fund financial statements, but are recognized as revenues in government-wide financial statements. The amount of property taxes receivable that are not available can be calculated as follows:

- Total property taxes receivable as of 12/31/22: $80,000

- Less: Property taxes receivable expected to be collected within 60 days of year-end: $60,000

- Property taxes receivable that are not available as of 12/31/22: $20,000

- The resulting amount is the net position of governmental activities as reported in the government-wide statement of net position.

The reconciliation can be presented in a table format as follows:

| Reconciliation of Total Fund Balance to Net Position | Amount |

| ----------------------------------------------------- | ------ |

| Total fund balance - governmental funds | \$200,000 |

| Capital assets used in governmental activities are not financial resources and therefore are not reported in the funds | \$5,270,000 |

| Long-term liabilities applicable to governmental activities are not due and payable in the current period and therefore are not reported in the funds | \(-\$3,580,000\) |

| Revenues in the statement of activities that do not provide current financial resources are not reported as revenues in the funds | \$20,000 |

| Net position - governmental activities

Gabriel was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 33%. What number should he multiply the cost of the meal by to find the total plus tip in one step?

Answers

1.33 should be multiplied to the cost of the meal to find the total plus tip in one step.

To find the total cost of the meal plus the 33% tip, Gabriel needs to multiply the cost of the meal by a factor of 1.33 (which represents the original cost plus 33% of the original cost).

So the total cost including the tip can be found by multiplying the cost of the meal by 1.33.

For example, if the cost of the meal was $50, the total cost including the tip would be:

Total cost = Cost of the meal + 33% tip

Total cost = $50 + 0.33($50)

Total cost = $50 + $16.50

Total cost = $66.50

Therefore, Gabriel should multiply the cost of the meal by 1.33 to find the total cost including the 33% tip in one step.

Write the following equation in polar form.
y=3


r=3sinθ
r=1/3sinθ
r=3cscθ
r=1/3cscθ
r=3cosθ
r=1/3cosθ

Answers

Answer:r=3cscθ

Step-by-step explanation:The equation y = 3 represents a horizontal line at a distance of 3 units above the x-axis in the Cartesian coordinate system. To convert this equation into polar form, we can use the fact that x = rcos(theta) and y = rsin(theta) in polar coordinates.

Since y = 3 for all values of x, we can say that r*sin(theta) = 3. Solving for r, we get:

r = 3/sin(theta)

This equation represents a family of circles with center at the origin and radius 3/sin(theta), for all values of theta except for multiples of pi. We can simplify this equation by using the identity sin(theta) = 1/csc(theta), giving us:

r = 3csc(theta)

Water is pumped out of the conical tank with vertex down and radius 8 ft and height 20 ft. If the volume is decreasing at a rate of 4 ft^3sec :

how fast is the depth of the water decreasing when the water is 9 ft deep? (Note: Don't approximate the answer and state its exact value in terms of π.)

Answers

It took approximately 151 seconds to decrease 9 ft water in conical tank.

The volume of a conical tank with vertex down and radius 8 ft and height 20 ft is V = (1/3)πr²h

When the water is 9 ft deep

= (1/3) ×3.14×(8)²×(9)

= 602.88 ft³

We know that the rate of change of volume is 4 ft³/sec. So, the rate of change of depth can be calculated as follows:

Rate of change of depth (dh/dt) = Volume of tank/4 ft³ per sec

= 602.88/4

= 150.72 sec

Therefore, it took approximately 151 seconds to decrease 9 ft water in conical tank.

What are the x-intercepts for the graph y = cos x, where
0≤x≤ 2n?

Answers

The x-intercepts for the function y = cos x, where 0≤x≤ 2n are

x = π/2, x = 3π/2, and x = 2π

We have,

The cosine function has an x-intercept whenever it crosses the x-axis, which happens at every multiple of π/2 radians (or 90 degrees).

So the x-intercepts for the graph y = cos x, where 0 ≤ x ≤ 2π are at

x = π/2, x = 3π/2, and x = 2π

(corresponding to 90 degrees, 270 degrees, and 360 degrees).

Now,

If we take 2n to be a multiple of 2π (i.e., 2n = k2π for some integer k), then the x-intercepts for the graph y = cos x,

where 0 ≤ x ≤ 2n, will be at x = kπ/2 for k = 0, 1, 2, ..., 4n-1.

The x-intercepts for the graph y = cos x, where 0≤x≤ 2n are

x = π/2, x = 3π/2, and x = 2π

Pat and Jeff walk to dock at 2 mph, jumped into the boat, and motored to Dillon at 8mph. If the total distance is 13 miles and trip took 11/4 in all, how far did boat go?

Answers

Let's start by using the formula:

distance = rate x time

Let d be the distance the boat traveled, in miles.

The time it took Pat and Jeff to walk to the dock is the same as the time it took them to motor to Dillon, so we can write:

d/8 = (13 - d)/2

Simplifying this equation, we get:

d = 8(13 - d)/2

d = 52 - 4d

5d = 52

d = 10.4

Therefore, the boat traveled a distance of 10.4 miles.
