The answer is 0 because If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring.

What is the total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months?
Rom4ik [11]
Since only the principal value, interest rate and interest period are given, we can deduce that "finance charge" only includes the interest to be paid at the end of the term. This can be obtained by subtracting the principal value from the future value which we will solve for.

The future value can be solved by using the following compound interest formula:

Let:
F = Future value
P = Principal value
r<span> = annual interest rate </span>
n<span> = number of times that interest is compounded per year</span>
t<span> = number of years</span>

F = P(1 + r/n)^nt

Substituting the given values:
F = 4250(1 + 0.1325/12)^(12*2)
F = 5531.54

Subtracting P from F:
Finance charge = 5531.54 - 4250 = 1281.54

Therefore the finance charge is $1,281.54

Find the probability of rolling a sum of two dice that is a 7 or a 12. Round answer to 4 decimal places
cricket20 [7]

Answer:

The probability is 0.1944

Step-by-step explanation:

Since we are rolling two dice, the number of possible results is 36

for us to get a sum of seven, these are the possible results;

1 and 6

6 and 1

2 and 5

5 and 2

3 and 4

4 and 3

The probability of rolling a sum of 7 is 6/36

For a sum of 12, we only have one possible result and that is 6,6

So the probability here is 1/36

If we have or in probability, we add up the individual probabilities

So, our probability here will be;

1/36 + 6/36

= 7/36 = 0.1944

A farmer counted a total of 9 eggs in 8 hens nest. What was the average number of eggs in each nest
maria [59]
Average=total/amount

Since the total eggs were 9, and you counted 8 hen nests, 

9/8= 1.125
Because you cannot have 1.125 eggs, the average is about 1 egg.

What is the scale of a map if 1 cm on a map represents 20 km in real life.
Varvara68 [4.7K]

Answer:

1 : 2,000,000

Step-by-step explanation:

1cm : 20 km  (recall 1 km = 100,000 cm)

1cm : 20 x 100,000 cm

1cm : 2,000,000 cm

hence scale is 1 : 2,000,000
