PLEASE ONLY DO THE LAST PORTION " Final Questions." I already did all the other ones.

Your friend, another accountant, has bet you that with your knowledge of accounting and just the computations for common analytical measures, you can figure out many aspects of a company's financial statements. You take the bet!

Match each computation to one of the liquidity and solvency measures in the table. (Hint: Begin by looking for simple computations and identifying the amounts in those computations. Look for other measures that use those amounts.)

Use the following balance sheet form to enter amounts you identify from the computations on the Liquidity and Solvency Measures panel. You will identify other amounts for the balance sheet on the Profitability Measures panel. If you have a choice of two amounts, assume the first amount in the ratio is for the end of the year. Compute any missing amounts.

Match each computation to one of the profitability measures in the table.

Use the following comparative income statement form to enter amounts you identify from the computations on the Liquidity and Solvency Measures panel and on the Profitability Measures panel. Compute any missing amounts and complete the horizontal analysis columns. Enter percentages as decimal amounts, rounded to one decimal place. When rounding, look only at the figure to the right of one decimal place. If < 5, round down and if ? 5, round up. For example, for 32.048% enter 32.0%. For 32.058% enter 32.1%.

Your accountant friend reveals that the company whose information you have been working on is actually a company he is thinking of investing in. What advice and insight do you have for your friend?

Using only the information from your horizontal analysis of the comparative income statement, complete the following sentences.

has decreased significantly from 20Y5 to 20Y6, even though has increased. However, has also , which slowed the increase in . In addition, has increased at a faster rate. The company appears .

Based on these observations, do you recommend that your friend invest in this company’s stock?

Consider a call option with a premium of $8 for which the exercise price is $50. What is the profit for a holder if the underlying stock price at expiration is $60.00? What is the profit for the seller?

ALei Industries has credit sales of $151 million a year. ​ ALei's management reviewed its credit policy and decided that it wants to maintain an average collection period of 40 days.

a.  What is the maximum level of accounts receivable that ALei can carry and have 40​-day average collection​ period?

b.  If​ ALei's current accounts receivable collection period is 50 ​days, how much would it have to reduce its level of accounts receivable in order to achieve its goal of 40 ​days?

Round to one decimal place.

So, I'm trying to get revolutions/second from a given binary data.

for example, the input binary data is:

V=[0 1 0 0 1 0 0 0 1 0 1 1 0 0 0 0 0 1 0 ]

let's say the distance between each value is arbitrary (for this example, you can use 0.1). Each 1 represents a full rotation of a bike pedal, and I'm trying to calculate the pedal rate from a given binary dataset in Matlab. How would I do so?

EDIT for clarification:

So, I'll be receiving data from a bike as a binary vector (0s and 1s). Each 0 or 1 represent a measurement. I think each number represents like a certain time. So the vector [0 1 0 0 1 ] would mean two rotations and just a guess at the time between each value is .1 seconds. So the cadence would be 1 rev/.3s.

I'm trying to figure out how to write a program to read the given vector and output a cadence.

Measuring the height of a particular species of tree is very difficult because these trees grow to tremendous heights. People familiar with these trees understand that the height of a tree of this species is related to other characteristics of the​ tree, including the diameter of the tree at the breast height of a person. The accompanying data represent the height​ (in feet) and diameter​ (in inches) at the breast height of a person for a sample of 21 trees of this species.

Height   Diameter at breast height

C. Interpret the meaning of the coefficient of determination in this problem. The value is?

D. Determine whether there is a significant relationship between the height of trees of this species and the​breast-height diameter at the 0.05 level of significance.

The Wind Mountain excavation site in New Mexico is an important archaeological location of the ancient Native American Anasazi culture. The following data represent depths (in cm) below surface grade at which significant artifacts were discovered at this site (Reference: A.I. Woosley and A.J. McIntyre, Mimbres Mogollon Archaeology, University of New Mexico Press).

Bowman Specialists Inc. (BSI) manufactures specialized equipment for polishing optical lenses. There are two models—one (A–25) principally used for fine eyewear and the other (A–10) for lenses used in binoculars, cameras, and similar equipment.

The following table shows the manufacturing cost of each unit is calculated, using activity-based costing, for these manufacturing cost pools.

BSI currently sells the A–10 model for $3,770 and the A–25 model for $2,015. Manufacturing costs and activity usage for the two products follow:

Required:

1. Calculate the product cost and product margin for each product.

2. A new competitor has entered the market for lens-polishing equipment with a superior product at significantly lower prices, $2,415 for the A–10 model and $1,890 for the A–25 model. To try to compete, BSI has made some radical improvements in the design and manufacturing of its two products. The materials costs and activity usage rates have been decreased significantly, as follows:

2-a. Calculate the total product costs with the new activity usage data.

2-b. Can BSI make a positive gross margin with the new costs, assuming that it must meet the price set by the new competitor?

4. What cost management method might be useful to BSI at this time?

What percentage of bulbs will have a life between 1350 and 1377 hr? 2. What percentage of bulbs will have a life between 1341 and 1350 hr? 3. What percentage of bulbs will have a life between 1338 and 1365 hr? 4. What percentage of bulbs will have a life between 1365 and 1377 hr? 5. What percentage of bulbs will have a life between 1338 and 1344 hr? 6. What percentage of the bulbs will last longer than 1386 hr? 7. What percentage of the bulbs will last less than 1323 hr? 8. The 10 percent of the bulbs with the longest life will last longer than how many hours? 9. The 20 percent of the bulbs with the shortest life will last no longer than how many hours?

I am looking for help with 7-9. Looking for the math worked out, to find the answer. Thanks
