Answer:
Simple interest = $36
Compound interest = $48.96
It's better to invest $600 at 4% compounded monthly for 2 years as it's giving us more profit.
Step-by-step explanation:
Simple interest is calculated on the principal amount of a loan. Compound interest is calculated on the sum of principal amount and accumulated interest of previous periods.
Simple interest =
Compound interest =
Here, P denotes principal amount, R denotes rate of interest, T denotes time.
Given: $600 invested at 3% simple interest for 2 years, $600 invested at 4% compounded monthly for 2 years
To find: Simple interest and compound interest.
Solution:
Take P=600, R=3% and T=2 years
Using the formula of simple interest mentioned above,
Simple interest =
So, interest earned is $36
Take P=600, R=4% and T=2 years
Using the formula of compound interest mentioned above,
Compound interest =
=
=
=
=
So, interest earned is $48.96
It's better to invest $600 at 4% compounded monthly for 2 years as it's giving us more profit.
Answer:
The correct selections are:
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups.
C) A placebo is not being used
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call.
Step-by-step explanation:
What this question requires from you, is to identify the correct characteristics of the study described. Let us explain why each of the selections was made.
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups: The purpose of the study is to determine the difference in the effectiveness of two methods of fundraising. Therefore at the end of the study, the average total amount raised from each group will be compared to determine which was more effective.
C) A placebo is not being used: Placebos are sham treatments used in a control group without their knowledge. The placebos do not produce any effect similar to the results anticipated the actual treatment. Here, no group is given sham treatment, there is no "control" group given placebos hence placebos are not used.
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call: To remove any form of bias in the study, the selection of the groups is done at random, and the number of participants in each group is the same, so as to maintain uniformity during the comparison.
Answer:
1,614,312.
Step-by-step explanation:
0.59% = 0.0059 as a decimal fraction.
Population in 2016 = 1,624,000 - 0.0059 * 1,624,000
= 1614312
