Answer:
a) 
b) It takes 5.390 years to pay off the loan.
Step-by-step explanation:
(a) The differential equation for the variation in the amount of the loan M is
We can express this equation as:
(b) We can calculate this as M(t)=0
It takes 5.390 years to pay off the loan.
Answer:
we have to compare the effects of method I and method II.
(a)
(i) The population of generalization if the method I is used will be all people who are willing to determine the effect of exercising with a training partner as compared to exercising alone.
(ii) The population of generalization, if method II is used, will be all people who exercise at a community fitness center.
(b)
If both the methods produce significant results then the difference between the conclusion of the method I and the conclusion of method II is that the result of the method I can be generalized to a broader population since it does not restrict people to participate in the study.
Answer:
69.1
Step-by-step explanation:
<em>Mean height of 14 students = 69.0 inches</em>
<em>Mean = sum of data/number of data</em>
<em>69 = sum of data/14</em>
<em>sum of data = 966</em>
<u>FOR NEW MEAN:</u>
<em>Height of additional student = 70.5</em>
Mean = sum of data/ number of data
Mean = 966+70.5/14+1
Mean = 1036.5/15
Mean = 69.1
Therefore, the mean height of the 15 students in the class is 69.1
