Step-by-step explanation:
In this case in order to simplify we need to know what the "power rule of exponents" is. Simply speaking this rule states that when you raise a power to a power you multiply the exponents. So in our case we ill get the following
=
In order to get 42 we used the power rule which I mentioned earlier.
The probability that a student participates in both sports and drama is .
If and
are any two events, then the probability of the joint event
is given by the following formula:
Given that 42% of the students participate in sports and 25% of the students participate in drama and 53% of the students participate in either sports or drama.
Suppose denotes that "a student participates in sports" and
denotes that "a student participates in drama".
So, we have ,
,
.
We want to find the probability that a student participates in both sports and drama i.e., we want to find .
By the above formula, we obtain:
Therefore, the probability that a student participates in both sports and drama is .

Answer:
The APR at which the money is borrowed, is approximately 651.79%
Step-by-step explanation:
The amount which one wishes to borrow for two weeks, P = $600
The amount of interest that one must pay back = $25 per $100 borrowed
Therefore;
The total interest on the $600 loan (borrowed) for two weeks = 25/100× $600 = $150
The number of days for which the amount was borrowed = 2 weeks = 14 days
The Annual Percentage Rate, APR is given as follows;
Therefore, we get
The annual rate at which the money is borrowed, APR ≈ 651.79%.
