Find the savings plan balance after 3 years with an APR of 7% and monthly payments of $150.

Citrus2011 [14]

Answer:

The balance is $5989.5

Step-by-step explanation:

The savings plan balance is given by the following formula:

$A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]$

In which A is the savings plan balance, P is the monthly payment, APR is the annual percentage rate(decimal), n is the number of payments per year and Y is the number of years.

In this problem, we have that

Find the savings plan balance after 3 years with an APR of 7% and monthly payments of $150.

So we have to find A when $P = 150, APR = 0.07, n = 12, Y = 3$ .

$A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]$

$A = 150*\left[\frac{(1 + \frac{0.07}{12})^{12*3} - 1}{\frac{0.07}{12}}\right]$

$A = 5989.5$

The balance is $5989.5

Find the probability of randomly rolling 2 standard dice and having a sum that is EVEN or GREATER THAN 9.

Ede4ka [16]

Answer:

Hence, the probability of randomly rolling 2 standard dice and having a sum that is EVEN or GREATER THAN 9 is 2/3

Step-by-step explanation:

Let A be the event that the sum of two dice is even

Then P(A) will be the probability of having even sum

As the sample space is already given in the image

n(S) = 36

A = {(1,1) , (1,3), (1,5), (2,2), (2,4), (2,6), (3,1), (3,3), (3,5), (4,2), (4,4), (4,6), (5,1), (5,3), (5,5), (6,2), (6,4), (6,6)}

n(A) = 18

So,

P(A) = n(A)/n(S)

= 18/36

= 1/2

Let B be the event that the sum is greater than 9

B = {(4,6), (5,5), (5,6), (6,4), (6,5), (6,6)}

n(B) = 6

P(B) = n(B)/n(S)

= 6/36

= 1/6

Now we have to find P(A∪B) i.e. P(A or B)

P(A∪B) = P(A) + P(B)

= 1/2 + 1/6

= (3+1)/6

=4/6

=2/3

Hence, the probability of randomly rolling 2 standard dice and having a sum that is EVEN or GREATER THAN 9 is 2/3 ..
