Answer : The total amount Mrs. Harrison pay back will be, $654
Step-by-step explanation :
Given:
Principle = $600
Rate = 9 %
Time = 1 years
First we have to determine the simple interest.
Formula used :
where,
P = principle
R = interest rate
T = time
S.I = simple interest
Now put all the given values in the above formula, we get:
The simple interest is, $54
Now we have to determine the total amount Mrs. Harrison will pay back.
Total amount = Principle + Simple interest
Total amount = $600 + $54
Total amount = $654
Thus, the total amount Mrs. Harrison pay back will be, $654

Answer:
15.6%
Step-by-step explanation:
Since each day there is a 6% chance that Lisa smiles at him then that means that each day there is a 94% chance that Lisa does not smile at him. To find the probability of Milhouse going longer than a month (30 days) without a smile from Lisa we need to multiply this percentage in decimal form for every day of the month. This can be solved easily by putting 94% to the 30th power which would be the same, but first, we need to turn it into a decimal...
94% / 100 = 0.94
= 0.156
Now we can turn this decimal into a percentage by multiplying by 100
0.156 * 100 = 15.6%
Finally, we can see that the probability that Milhouse goes longer than a month without a smile from Lisa is 15.6%
