Answer:
m<S=66.5
Step-by-step explanation:
The sum of the angles = 360
(6x-6)+(4x-10)+(5x-11)+(5x+13)+(4x+2) = 360
24x-12=360
24x=372
x=15.5
S=5x-11 = 5*15.5-11=66.5
Answer:
104
we have:
6x - 6 + 4x - 10 + 5x - 11 + 5x + 13 + 4x + 2 = 180.3
<=> 24x - 12 = 540
<=> 24x = 552
<=> x = 552/24
<=> x = 23
with x = 23, we have: m<S = 5.23 - 11 = 115 - 11 = 104

suppose net income = $200 , depreciations = $10, and working capital went up by $70. what was cash from operations?
Answers
cash from operations is $140 when net income = $200 , depreciations = $10, and working capital went up by $70.
Cash from Operations = Net Income + Depreciation - Change in Working Capital
Plugging in the values:
Cash from Operations = $200 + $10 - $70
Cash from Operations = $140.
So, cash from operations is $140.
Cash from operations can be calculated by adding non-cash items such as depreciation and subtracting changes in working capital.
This means that the company generated $140 in cash from its operations during the given period. It is important to understand the cash from operations as it represents the cash generated from the day-to-day operations of the business and provides an indication of its ability to generate cash in the future.

The classification of the equations as direct or indirect variations are;
1) Direct Variation
2) Direct Variation
3) Indirect Variation
4) Indirect Variation
How to find direct and indirect variation?Direct variation occurs when one quantity changes and the other quantity changes as well in direct proportion. Meanwhile, Inverse variation is exactly opposite of that.
Now, let us answer the questions;
1) y = 4x + 1
This shows that y is directly proportional to x because as x is increasing, y is increasing and vice versa. Thus, it is a direct variation.
2) y = 7.5x
This shows that y is directly proportional to x because as x is increasing, y is increasing and vice versa. Thus, it is a direct variation.
3) y = (1/15)x
This shows that y is inversely proportional to x because as x is increasing, y is decreasing and vice versa. Thus, it is an indirect variation.
4) y = 6/x
This shows that y is inversely proportional to x because as x is increasing, y is decreasing and vice versa. Thus, it is an indirect variation.

annual starting salaries for college graduates with degrees in business administration are generally expected to be between $42,000 and $55,400. assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. (round your answers up to the nearest whole number.) what is the planning value for the population standard deviation? (a) how large a sample should be taken if the desired margin of error is $500? (b) how large a sample should be taken if the desired margin of error is $200? (c) how large a sample should be taken if the desired margin of error is $100? (d) would you recommend trying to obtain the $100 margin of error? explain.
Answers
The planning value for the population standard deviation is estimated to be $3,350, and sample sizes of approximately 46, 566, and 2,262 would be needed to achieve desired margins of error of $500, $200, and $100, respectively.
(a) Desired margin of error = $500
The formula for the sample size required to estimate the population mean with a desired margin of error is:
n = (Z * σ / E)²
Where:
n = sample size
Z = Z-score corresponding to the desired confidence level (95% confidence level corresponds to a Z-score of 1.96)
σ = population standard deviation
E = desired margin of error
Since we don't have the actual population standard deviation, we can estimate it using the planning value.
Range of expected salaries = $55,400 - $42,000 = $13,400
Planning value for standard deviation = Range / 4 = $13,400 / 4 = $3,350
Substituting the values into the formula:
n = (1.96 * $3,350 / $500)² ≈ 45.96
Since we can't have a fraction of a sample, we need to round up to the nearest whole number.
Therefore, the sample size needed for a desired margin of error of $500 is 46.
(b) Desired margin of error = $200
Using the same formula:
n = (1.96 * $3,350 / $200)² ≈ 565.44
Rounding up to the nearest whole number, the sample size needed for a desired margin of error of $200 is 566.
(c) Desired margin of error = $100
Using the same formula:
n = (1.96 * $3,350 / $100)² ≈ 2,261.76
Rounding up to the nearest whole number, the sample size needed for a desired margin of error of $100 is 2,262.
(d) Would you recommend trying to obtain the $100 margin of error? Explain.
Obtaining a margin of error as low as $100 would require a sample size of 2,262. While this larger sample size may provide a more precise estimate, it also increases the cost and time required for data collection and analysis. Therefore, the decision to obtain such a small margin of error should be based on the practicality and resources available. It is important to consider the trade-off between the desired level of precision and the associated costs and efforts.
Therefore, the planning value for the population standard deviation is estimated to be $3,350, and sample sizes of approximately 46, 566, and 2,262 would be needed to achieve desired margins of error of $500, $200, and $100, respectively.

This summer you are working at a local Veterinian Office. The vet asked you to help her design an outdoor rectangular dog kennel that will fit some of their larger patients. Because the vet's office is working on a budget, she does not know the total amount of fencing she will be able to purchase to secure the perimeter of the kennel. However, she does know that to fit some of the patients it must be 6 feet in width. Here is your task, find a formula that allows you and the vet to find the length of the kennel once she has purchased a set amount fencing for the perimeter and you know that the width is 6 feet on both sides. Use the formula for perimeter: \large P=2w+2l
Answers
Step-by-step explanation:
in this problem we are going to assume that the vet purchased a total amount of 100ft fencing.
we know that the perimeter of a rectangle is given as
P=2w+2l
given data
width w= 6ft
Perimeter P= 100ft
length l=?
Substituting into the expression for the perimeter we have
100=2(6)+2l
100=12+2l
100-12=2l
88=2l
l=88/2l
l=44
Therefore if the perimeter is 100ft the length will be 44ft given that the width must be 6ft
Note: you can assume any value for the perimeter to arrive at a solution using the formula for perimeter

Scenario 1B:
Remaining amount for Insurance and patient to pay is $350
Coinsurance amount is $70
Total paid by patient is $170
Medicare payment is $280
Provider write-off is $370
Scenario 1A:
Submitted charge: $650
Medicare participating physician fee schedule (PFS): $450
Coinsurance amount (20% paid by patient): $
Medicare payment (80% of the PFS): $
Provider write-off: $
To calculate the missing amounts, we can use the provided information:
Coinsurance amount (20% paid by patient):
Coinsurance amount = 20% of the Medicare participating physician fee schedule (PFS)
Coinsurance amount = 0.2 * $450 = $90
Medicare payment (80% of the PFS):
Medicare payment = 80% of the Medicare participating physician fee schedule (PFS)
Medicare payment = 0.8 * $450 = $360
Provider write-off:
Provider write-off = Submitted charge - Medicare payment
Provider write-off = $650 - $360 = $290
Scenario 1B:
Submitted charge: $650
Medicare participating physician fee schedule (PFS): $450
Patient pays $100 remaining on their deductible
Remaining amount for Insurance and patient to pay: $
Coinsurance amount (20% of remaining amount): $
Total paid by patient (deductible & 20% of remaining): $
Medicare payment (80% of the remaining amount): $
Provider write-off: $
To calculate the missing amounts, we can use the provided information:
Remaining amount for Insurance and patient to pay:
Remaining amount for Insurance and patient to pay = PFS - remaining deductible
Remaining amount for Insurance and patient to pay = $450 - $100 = $350
Coinsurance amount (20% of remaining amount):
Coinsurance amount = 20% of the remaining amount
Coinsurance amount = 0.2 * $350 = $70
Total paid by patient (deductible & 20% of remaining):
Total paid by patient = remaining deductible + coinsurance amount
Total paid by patient = $100 + $70 = $170
Medicare payment (80% of the remaining amount):
Medicare payment = 80% of the remaining amount
Medicare payment = 0.8 * $350 = $280

solve t^2y'+2ty-y^3=0
Answers
The general solution to the given differential equation is
y = ± √(1 / (2ln|t| + 4/t - C2))
Solution to the differential equationTo solve the given differential equation, we can use the method of separable variables. Let's go through the steps:
Rearrange the equation to separate the variables:
t^2y' + 2ty - y^3 = 0
Divide both sides of the equation by t^2:
y' + (2y/t) - (y^3/t^2) = 0
Now, we can rewrite the equation as:
y' + (2y/t) = (y^3/t^2)
Separate the variables by moving the y-related terms to one side and the t-related terms to the other side:
(1/y^3)dy = (1/t - 2/t^2)dt
Integrate both sides of the equation:
∫(1/y^3)dy = ∫(1/t - 2/t^2)dt
To integrate the left side, let's use a substitution. Let u = y^(-2), then du = -2y^(-3)dy.
-1/2 ∫du = ∫(1/t - 2/t^2)dt
-1/2 u = ln|t| + 2/t + C1
-1/2 (y^(-2)) = ln|t| + 2/t + C1
Multiply through by -2:
y^(-2) = -2ln|t| - 4/t + C2
Now, take the reciprocal of both sides to solve for y:
y^2 = (-1) / (-2ln|t| - 4/t + C2)
y^2 = 1 / (2ln|t| + 4/t - C2)
Finally, taking the square root:
y = ± √(1 / (2ln|t| + 4/t - C2))
Therefore, the general solution to the given differential equation is:
y = ± √(1 / (2ln|t| + 4/t - C2))

You can easily find the percentage of dogs that are walked at least 1.5 hours but under 4.2 hours per week by counting the number of data values in the appropriate class and dividing by the total number of data values, then multiplying by 100.
How you can create a histogram?Determine the range of the data: 0.6 to 4.7.
Divide the range by the number of classes (5) to find the class width: (4.7 - 0.6) / 5 = 0.76.
Determine the lower limits of each class by starting at the minimum value (0.6) and adding the class width repeatedly: 0.6, 1.36, 2.12, 2.88, 3.64, 4.4.
Count the number of data values that fall into each class and record it in a table.
Draw a bar for each class using the lower limit of the class as the x-axis value and the height of the bar equal to the number of data values in the class.
