The last one so work samples etc are the best examples
Answer:
TFC : Horizontal Line parallel to X axis
TVC : Upward sloping inverse S shape curve from origin
TC : Upward sloping increase S shape curve, with Y axis intercept = TFC
Explanation:
Total Fixed cost [TFC] is the total production expenditure, done on fixed factors of production (Eg - on machine, building etc). It is incurred even at zero level of output, stays same (constant) irrespective of output level. So, it's curve is a constant horizontal line.
Total Variable Cost [TVC] is the total production expenditure, done on variable factors of production (Eg - on raw material). It is zero at zero level of output, directly related to level of output thereafter. It first increases at a decreasing rate, then increases at an increasing rate. So, it's curve is inverse S upward sloping curve from origin.
Total Cost [TC] is the total cost incurred on all factors of production (fixed & variable). It is sum of TVC & TFC. As TFC is constant at all levels of output, TC changes due to change in TVC. So, TC is also directly related to output level, first increases at increasing rate & then at decreasing rate. Hence, it is also a inverse S upward sloping curve. But, it also includes constant TFC. So, the curve has intercept on Y axis = TFC (it doesn't start from origin).
The complete question is as follows:
The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?
Answer: The 95% confidence interval about the mean is 
.
The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.
We follow these steps to arrive at the answer:
Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.
The formula for the confidence interval about the mean is:
In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.
The Critical Value of Z at the 95% confidence level is 1.96.
Substituting the values in the question in the equation above we have,
Answer:
$7073.68
Explanation:
Data provided in the question:
Worth of portfolio = $15,000
Amount invested in stock A = $6,000
Beta of stock A = 1.63
Beta of stock B = 0.95
Beta of portfolio = 1.10
Now,
Beta portfolio = ∑(Weight × Beta)
let the amount invested in Stock B be 'x'
thus,
1.10 = [($6,000 ÷ $15,000 ) × 1.63] + [( x ÷ $15,000 ) × 0.95 ]
or
1.10 = 0.652 + [( x ÷ $15,000 ) × 0.95 ]
or
0.448 = [( x ÷ $15,000 ) × 0.95 ]
or
x = ( 0.448 × $15,000 ) ÷ 0.95
or
x = $7073.68
The answer is Pool Cleaning Systems. The relevant market product is Pool Cleaning System. It is engineered to clean the entire pool, including floors, steps, benches, even spas. Nozzles pop up consecutively to direct a power jet of water to direct debris towards the MDX-R3 drain.
