$121=every month
12=month

21. X
——= ———-
100. 1200
Cross multiply
21*1200=25200
100*x=100x
25200/100=252
So Loki paid $252 interest

Answer:

$252

Step-by-step explanation:

IN order to calculate how much interest will Loki pay when he finishes paying his debt we just have to multiply the number of months by the monthly payment:

Number of months* Monthly payment= Total

12*121=1452

To the total he paid we just withdraw the amount he got loaned:

Total-loan=Interests

1452-1200=252.

So we know he at the end of the loan will have paid 252 dollars in interests.

7. The claim that started this investigation was that students majoring in engineering are more likely to be in the marching ban
Genrish500 [490]

Answer:

See explanation below.

P(M|E) > P(M|O)

Step-by-step explanation:

Notation

First we need to define the following events:

E = The student is in a major of enginnering

O= The student is in a major different from enfinnering

M= The student is in the marching band

Solution for the problem

For this case we can calculate the following probability:

P(M|E) =\frac{P(M and E)}{P(E)}

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability  the student is in the marching band"

And the probability that need to calculate to compare is this one:

P(M|O) =\frac{P(M and O)}{P(O)}

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability  the student is in the marching band"

And if the claim is satisfied we need to see this:

P(M|E) > P(M|O)
