Answer:
93% probability of a student taking a calculus class or a statistics class
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a student takes a calculus class.
B is the probability that a student takes a statistics class.
We have that:
In which a is the probability that a student takes calculus but not statistics and is the probability that a student takes both these classes.
By the same logic, we have that:
The probability of taking a calculus class and a statistics class is 0.07
This means that
The probability of taking a statistics class is 0.90
This means that . So
The probability of a student taking a calculus class is 0.10
This means that
What is the probability of a student taking a calculus class or a statistics class
93% probability of a student taking a calculus class or a statistics class
Answer:
Current monthly payment on their existing mortgage would be $1158.66
Step-by-step explanation:
Total cash value = $160,000
Down payment = 10% of 160,000
Down Payment = $16,000
Balance amount = 160,000 - 16,000 = $144,000
Monthly payment formula:
where,
PV is present value of home, PV=$144,000
r is rate per period ,
n is number of period, n=30x12 = 360
Monthly payment would be same for 30 years.
Thus, Current monthly payment on their existing mortgage would be $1158.66
