Answer:
D) being unable to engage in all three of the above activities.
Explanation:
An opportunity cost is the cost (or lost benefit) of choosing one activity or investment over another. In this case, if the student decides to attend afternoon class, he/she will not be able to benefit from:
- taking a nap
- seeing a movie with a friend
- studying for next morning's test
So all the three activities represent the opportunity cost of attending afternoon class.
Answer:
Annual deposit = $4100
Explanation:
Annual deposit = $4100
Number of years for retirement = 30 years
Future value of money = $1000000
Interest rate = 12%
Now use the below formula to find the annuity amount.
Annual deposit = Future value (A/F, r, n)
Annual deposit = 1000000 (A/F, 12%, 30)
Annual deposit = 1000000(0.0041)
Annual deposit = $4100
The researcher wants to investigate whether carpet makes a difference in the mean bacterial concentration in air. the null and alternative hypotheses would be:
H0: The mean of the carpeted rooms = the mean of the uncarpeted rooms
Ha: The mean of the carpeted rooms ≠ the mean of the uncarpeted rooms
The attention of bacteria majorly depends on the awareness of inoculum, incubating temperature, and the metabolic country of inoculated pressure used. The bacterial concentration suspended in growth media may be calculated.
In idea, you could listen to cells through filtration or centrifugation, but likely no greater than a hundredfold. for your case, you're asking to concentrate by 10,000 fold. So you sincerely might want to develop denser cultures of cells. You can centrifuge your modern broth and resuspend the pallet in a clear broth.
In microbiology, the minimal inhibitory attention (MIC) is the lowest concentration of a chemical, generally a drug, which prevents the visible boom of a bacterium or bacteria.

Answer:
The project to accept is:
e. E
Explanation:
a) Data and Calculations:
Cost of capital = 10%
Mutually Exclusive Projects:
A B C E
Payback (years) 1 5 2 5
IRR 18% 20% 20% 12%
NPV (Millions) $40 $75 $35 $100
b) Project E should be preferred over all the other projects. It has the highest net present value (NPV) and its internal rate of return (IRR) is above the company's cost of capital. It surpasses projects A, B, and C in financial performance terms using time-value of money analysis.
