Answer:

The answer is letter A.

Explanation:

Less than or equal to 0.1

Because:

Average proportion (P-bar)= 0.024

Observations (n)= 75

sd =√(P-bar)(1-(P-bar)/n

sd =√(0.024)(1-0.024)/75

sd= √(0.024)(0.976)/75

sd= √(0.023424)/75

sd= 0.01767

sd ≤ 0.1

charle [14.2K]

The current worth of an anticipated future stream of cash flow is known as the present value, or PV. Using Microsoft Excel, present value may be estimated rather rapidly.

The net present value, or NPV, returns the cash flows' net value in today's currency. The future value FV is divided by a factor of 1 + I for each interval between the present date and the future date in the present value formula, PV=FV/(1+i)n. For the PV calculation, enter the following data into the present value calculator: The FV, or future value.

Eduardwww [97]

Answer:

(C) Pass-through grant

Explanation:

A pass-through grant occurs when a recipient of a grant is allowed by the government to provide funding to other recipients. Funds are received and passed along to other recipients.

The party that receives funding from the pass-through entity is called the subrecipient.

This usually occurs when government lacks the structure to effectively push grant initiatives.

In this instance when states provide funds to the city for onward delivery to not for profit organisations, the city is acting as a pass-through entity.
