What conclusions can be drawn using the given and its diagram?
dem82 [27]

Answer:

Whichever reasoning processes and research methods were used, the final conclusion is critical, determining success or failure. If an otherwise excellent experiment is summarized by a weak conclusion, the results will not be taken seriously.

Success or failure is not a measure of whether a hypothesis is accepted or refuted, because both results still advance scientific knowledge.

Failure lies in poor experimental design, or flaws in the reasoning processes, which invalidate the results. As long as the research process is robust and well designed, then the findings are sound, and the process of drawing conclusions begins.Whichever reasoning processes and research methods were used, the final conclusion is critical, determining success or failure.

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul
VARVARA [1.3K]

Answer:

B. An increase in i, the interest rate, will create an increase in P, the monthly payment.

Step-by-step explanation:

We have the formula for the monthly payment as,

P=\frac{i \times PV}{1-(1+i)^{-n} },

where P = monthly payment, i = rate of interest, PV = present value and n = time period.

Now, as i increase we get that (1+i) increases and so (1+i)^{n} increases.

This gives us that, \frac{1}{(1+i)^{n} } decreases and so 1-\frac{1}{(1+i)^{n}} decreases

Therefore, \frac{1}{1-(1+i)^{-n} } increases.

So, we get that as i increases , the value of P will increase.

Hence, option B is correct.
