A wealthy man just died and left his pet dogs the following estate: $20,000 per year for the next 11 years with the first cash f

Andre45 [30]

The concept of present value lets us know that the doggy estate worth in today's dollars is $180614.80

<h3>What is the present value of the doggy estate worth?</h3>

The concept of present value is significant because it enables investors to determine whether the amount they pay for an investment is reasonable. The present value of a future cash flow defines how much it is worth in today's value.

From the given information:

The annual cashflow C = $20,000
Interest rate (i) = 4.2% = 0.042
Number of period (n) = 11

Thus, the present value of the doggy estate can be calculated by using the formula;
$\mathbf{PV = C \times \Big [ \dfrac{1 - \dfrac{1}{(1+i)^n}}{i}\Big] \times (1+i)}$

$\mathbf{PV = 20000 \times \Big [ \dfrac{1 - \dfrac{1}{(1+0.042)^{11}}}{0.042}\Big] \times (1+0.042)}$

PV = $180614.80

A scientist wants to make certain the results of her experiment are accurate. She has repeated the procedure numerous times and

Romashka [77]

The correct answer is D. Have other scientists repeat the procedure and obtain the same results.

Explanation:

One of the most accurate ways to validate the results of an experiment is to allow peers (other scientists) to review the experiment and repeat it, which is known as replication. This process is required to make sure the results are accurate because if the experiment is repeated by a different scientist and the results are different this shows the data is not consistent and therefore the results are invalid. Moreover, inconsistency or lack of replication can occur due to incorrect processes or bias by the scientist.

According to this, the next step in this situation is to "have other scientists repeat the procedure and obtain the same results".On the other hand, repeating the experiment but changing one of the variables or the procedures is not a correct step because this will change the essence of the experiment and lead to different results.
