You are analyzing Delta Enterprises, a small publicly traded company with
$50 million of debt outstanding, and 25 million shares, trading at $10/share.
The firm generated $40 million in after-tax cash flows last year, and you esti-
mate that these cash flows will grow 2% a year in perpetuity and that the cost
of capital for the firm is 12%.
a. Estimate a value per share for the firm, assuming it has no cash balance.
b. Now assume that you find out that a significant portion of the firm’s revenues
comes from one customer and that there is a 20 percent chance that this con-
tract will be lost next year. Assuming that a lost contract will result in a 50%
drop in the after-tax cash flows, estimate the value per share today. (You can
assume that the growth rate and cost of capital will be unaffected).

In an effort to characterize the New Guinea crocodile (Crocodylus novaeguineae), measurements were taken of the dorsal cranial length (mm) (the length of the skull from the tip of the nose to the back of the cranial cap, denoted DCL) and the total length (cm) (denoted TL) of 50 harvested adult males.

First, sort the data.
Second, build a GFDT for this table with a classwidth of
5.
(Be sure your lower class limits are multiples of the
classwidth.)
Next, answer the following questions about the data set:
1. What is the first lower class limit in your GFDT (given the
classwidth of 5)?
2. Express the third class as a closed interval, i.e.,
[a,b][a,b].
3. Give the frequency for the third class.
4. What is the (arithmetic) mean for this data (report accurate to
one decimal place)?
5. Using the GFDT, what is the mode for this data set (use the
appropriate definition for mode)?(take the class with the biggest
frequency [40,44], and apply the following formula (Lower class
limit+Upper class limit)/2
6. What is the standard deviation for this data (report accurate to
two decimal places)?
7. What is the five number summary for this data set (separate
numbers with a comma)?
8. What is the IQR?
9. What usual score (i.e., non-outlier) has the largest
positive z-score less than z=2z=2? (Give the data value,
not the z-score.)
10. Give the fences---this would suggest something other
than z-scores---for the mild outliers at the maximal end
of the data set; report as a closed interval, i.e., [upper
mild fence, upper extreme fence].
Need help with solving this problem, please dummy it down for me I would also like to know how to solve it. Please provide answers thanks!

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 64 students enrolled in those two courses. Data concerning the company’s cost formulas appear below:
| Fixed Cost per Month | Cost per Course | Cost per Student |
|||||
| Instructor wages | $ | 2,950 | |||||
| Classroom supplies | $ | 270 | |||||
| Utilities | $ | 1,220 | $ | 90 | |||
| Campus rent | $ | 4,600 | |||||
| Insurance | $ | 2,200 | |||||
| Administrative expenses | $ | 4,000 | $ | 44 | $ | 5 | |
For example, administrative expenses should be $4,000 per month plus $44 per course plus $5 per student. The company’s sales should average $870 per student.
The company planned to run four courses with a total of 64 students; however, it actually ran four courses with a total of only 60 students. The actual operating results for September appear below:
| Actual | ||
| Revenue | $ | 52,780 |
| Instructor wages | $ | 11,080 |
| Classroom supplies | $ | 17,130 |
| Utilities | $ | 1,990 |
| Campus rent | $ | 4,600 |
| Insurance | $ | 2,340 |
| Administrative expenses | $ | 3,922 |
Required:
1. Prepare the company’s planning budget for September.
2. Prepare the company’s flexible budget for September.
3. Calculate the revenue and spending variances for September.
