A magnet slid down the inclined aluminum ramp with a constant velocity, rather than accelerating. Alluminum is not a magnetic material so there should be no magnetic attraction between the magnet and the aluminum. Explain the process that caused this to happen.
Points will be awarded yo answer with most detail and examples.

A local fertility specialist noticed that some of her patients were heavy coffee drinkers. She wanted to know if there was any association between coffee drinking and conception in the first year of trying. She asked a random sample of 40 patients (some of whom have successfully become pregnant) about coffee drinking. The table below summarizes the data (table entries represent raw frequencies of women in terms of pregnant or not and coffee drinker or not). Using alpha =.01, use the 2-way Chi-square to determine whether there is any relation between successful pregnancy and coffee drinking.
Coffee
Yes (drinker)
No (no-drinker)
Pregnant
Yes (pregnant)
6
15
Not (not pregnant)
9

MIRR unequal lives. Singing Fish Fine Foods has $1,910,000 for capital investments this year and is considering two potential projects for the funds. Project 1 is updating the store's deli section for additional food service. The estimatedafter-tax cash flow of this project is $590,000 per year for the next five years. Project 2 is updating the store's wine section. The estimated annual after-tax cash flow for this project is $520,000 for the next six years. The appropriate discount rate for the deli expansion is 9.3% and the appropriate discount rate for the wine section is 8.8%. What are the MIRRs for the Singing Fish Fine Foods projects? What are the MIRRs when you adjust for unequallives? Do the MIRR adjusted for unequal lives change the decision based on MIRRs? Hint: Take all cash flows to the same ending period as the longest project.
If the appropriate reinvestment rate for the deli expansion is 9.3%, what is the MIRR of the deli expansion? _________% (Round to two decimal places.)
If the appropriate reinvestment rate for the wine section is 8.8%, what is the MIRR of the wine section? ________% (Round to two decimal places.)
Based on the MIRR, Singing Fish Fine Foods should pick the (Wine or Deli) project. (Select One.)
What is the MIRR adjusted for unequal lives of the deli expansion? ________% (Round to two decimal places.)
What is the MIRR adjusted for unequal lives of the wine section?________% (Round to two decimal places.)
Based on the adjusted MIRR, Singing Fish Fine Foods should pick the (Wine or Deli) section project. (Select One.)
Does the decision change? (Yes or No). (Select One)

Write a short essay. a. Explain what makes it an ethical question. b. Explore the ethical dimensions of the question. This should include alternate points of view about possible answers to the question. Using what you’ve learned from our textbook, the course, and elsewhere, draw conclusions about what aspects of the issue you believe are and are not ethical, presenting multiple perspectives on the issues and ultimately articulating and defending your point of view.

Steve is considering donating his personal car, a red Ford Mustang, to a qualified charity. He purchased it for $7,000 5 years ago but it has a fair market value of $12,000. The charity would sell the car and use the proceeds to help sick children. What amount would Steve be able to claim as a charitable contribution deduction if he donates the car?
(In response to comment for more info) There is no depreciation rate, the fair value has actually gone up, regardless this information is not needed for this problem and neither is the market interest rate.)

Compile the following C code to MIPS assembly.
a. Assume that i and j are stored in register $s1 and $s2, respectively. i = i – 2 + j;
b. Assume base address of Array B and the variable i are stored in registers $s3 and $s1, respectively. B[1] = (B[0] x 4) - I;
Explain each step in detail!
my professor has the following answer: 1) addi $t0, $s1, -2 add $s1, $$t0, $s2
2) lw $t0, 0 ($s3) #load B[0] into a register sll $t0, $t0, 2 #shift left logical A[2] x 4 #(may have several different ways) sub $t0, $t0, $s1 # (B[0] x 4) - i sw $t0, 4($s0)
Can you explain in detail why?
