Calculate the activity in mCi and MBq of In-113 produced by irradiation of 1 g of pure Cd-111 for 3 hr with 12 MeV protons having a beam intensity of 1x10¹³ particles/(cm²-sec). The cross section for formation of In-111 (T = 2.8 d) is 200 millibarns ( 1 mb = 1x10^-27 cm²). Recall 1 mCi = 37 MBq

1. Tell whether the lines are "parallel", "perpendicular", or "neither."
9x + 3y = 12
12x + 4y = 18

2. Write an equation of the line described.
Through (7, 1), parallel to -8x + 7y = -28

3. Do you prefer to use the method of plotting points or the method using the intercepts to graph an equation? y=2/3x-27? why

In an R.C. circuit, a 60 volt battery charges a 27 microfarad capacitor. It discharges in a resistance of R. The voltage of the capacitor is 30 volts after 4.6 milliseconds. Find the following:

1: the time constant of the circuit

2: the maximum charge

3: the capacitor's charge after half of the time constant

4: the amount of time that it takes for the capacitor to get to a voltage of zero

On July 1, 2017, Oriole Co. pays $13,740 to Waterway Insurance Co. for a 3-year insurance policy. Both companies have fiscal years ending December 31. Journalize the entry on July 1 and the adjusting entry on December 31 for Waterway Insurance Co. Waterway uses the accounts Unearned Service Revenue and Service Revenue.

Question 1:   The marketing department for your electronics company has determined the relationship between price and demand for a new smartphone: Price ($) = 150 – 0.01 x (Monthly Demand) The fixed costs for this item are $50,000 per month, and the variable cost per unit is $40.   Determine: a) What is the optimal production volume per month for this product? b) What is the maximum profit per month? c) What is the domain of profitable demand? d) Prepare a spreadsheet and chart that shows cost, revenue, and profit. (Use the chart type scatter with smooth lines, over a range of demand from 0 to 12,000 units per month. The chart must include axis titles and a legend that identifies the three curves.

Question 2: You hope to sell a product for $575 that has a variable cost per unit of $335.  Your fixed cost is from rent on the fully‐furnished factory in which your product is manufactured. a) If you sell 9000 units per year, what is the maximum monthly rent you can afford to pay in order to break even? b) If the rent was actually $58,000 per month, then what is your annual profit if you sell 7000 units per year?

Question 3: A regional airline is considering the addition of winglets to its CRJ200 aircraft, at a cost of $375,000 per plane. The winglets improve fuel economy from 3150 lbs of fuel per hour to 3020 lbs/hr. Assuming a fuel cost of $0.27 per lb, and an interest rate of 1% per month, how many hours each month must be flown in order for this upgrade to break even within 3 years?

Question 4: Your company has been renting forklifts at a cost of $7500 (each) per year.  If your company upgrades the warehouse to an integrated robotic system, then forklifts would no longer be needed. The upgraded warehouse costs $208,000 to construct, $11,000 each year to maintain, and will have a useful life of 25 years.  For an interest rate of 5% per year, how many forklifts could be rented each year and break even with the cost of the upgraded warehouse?  

Question 5: You have invested $26,500 to obtain equipment that enables you to generate $4550 in revenue each month, with monthly costs of $1725. For a monthly interest rate of 3%, how many months are required for you to pay off your initial investment?

Question 6: Your company has purchased surveying equipment for $43,500, and will utilize it for 8 years before selling it for $3250.  How much new revenue must this equipment generate each year in order to pay off the equipment and realize a return of 6% per year?  Note: solve this problem with the factor method or equation method, and then also set up a spreadsheet illustration of ‘Unrecovered Investment Balance’.  (Hint: we’ve done spreadsheets like this before, on HW 7 and ICE 12).

I would just like to know if ANOVA would be the correct test to use for the following problem below?

Fancy Fish, a fine dining upscale restaurant in Northridge, California and 2016 Open Table Diners’ Choice award winner, is enjoying its eighteenth season of providing delectable food, exceptional service, and beautiful outdoor dining experiences. “Saturday - Half-off Bottled Wine Night” has made Fancy Fish one of the San Fernando Valley’s favorite restaurants. Every Saturday night, guests can enjoy half-off every bottle of wine on the wine list while dining in the restaurant or on the terrace. The owner began offering “Saturday - Half-off Bottled Wine Night” in 2010 as an incentive for guests to dine at Fancy Fish when the economy was in a recession. Now that the economy is booming, the owner is considering whether the promotion should be continued, or even expanded. One concern is the effect that the promotion is having on the overall revenue generated from sales to the participants.

A random sample of 28 checks was collected over the course of one month of Saturday nights. Fourteen checks were from customers participating in the half-off promotion, and the other 14 checks were from customers not participating. The total revenue from each check (less alcohol, tax, and tip) is presented below. Do these data present sufficient evidence that the checks of participants is significantly different from checks of non-participants? What is your recommendation to the owner regarding the status of the promotion?

West Laboratory provides service The trial balance at 30 September 2019, before adjustments is as follows:

The following information relates to month end adjustments:

1. The useful life of the equipment was estimated to be 4 years with no residual value. West Laboratory uses straight-line method to calculate depreciation.

2. A few customers pay in advance for the laboratory services provided by West Laboratory. Fees of $6,000 were earned during the month by providing service to customers who had paid in advance.

3. Salaries earned by employees during the month but not yet recorded amounted to $23,000.

4. On 1 July 2019, West Laboratory prepaid $42,000 for 6 months’ rent for the period from July to December 2019.

5. On 1 January 2019, West Laboratory prepaid an insurance of $4,800 for the year from 1st January to 31st December 2019.

6. Medical service provided during the month but not yet billed or recorded amounted to

$4,600.

Required:

1. Prepare the adjusting entries for the month of September 2019.

1. Prepare an income statement after the above adjustments.

(c) The president of West Laboratory was informed that the financial statements would be available "as soon as the adjusting entries are made." Being a non-accountant, the president feels adjustments should not be necessary if the accounting department is operating in a competent manner. Does the need for adjusting entries at the end of the period imply that transactions are not being recorded properly? Why adjusting entries are needed? Explain.

Rock Solid Bank and Trust (RSB&T) offers only checking accounts. Customers can write checks and use a network of automated teller machines. RSB&T earns revenue by investing the money deposited; currently, it averages 5.90 percent annually on its investments of those deposits. To compete with larger banks, RSB&T pays depositors 0.50 percent on all deposits. A recent study classified the bank’s annual operating costs into four activities.

Data on two representative customers follow.

A. Compute RSB&T's operating profits.

B. Compute the profit from Customer A and Customer B, assuming that customer costs are based only on deposits. Interest costs = {{0.5:#,##0.00}} percent of deposits; operating costs are 4 percent (= $25,500,000/$637,500,000) of deposits. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

C. Compute the profit from Customer A and Customer B, assuming that customer costs are computed using the information in the activity-based costing analysis. (Do not round intermediate calculations. Round your answers to 2 decimal places. Loss amounts should be indicated by a minus sign.)
