I have seen this problem before, except it was worded differently. Is this the problem you wished to express?

1+4=5, 2+5=12, 3+6=21, 8+11=?

If so, then your answer is to simply add the last answer to the next problem. If not, then I am afraid I cannot help you.

1+4=5

5+2+5=12

12+3+6=21

21+8+11=40

Find f(x) if it is known that f(x−6)=12x−72.

zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation

This means that if you take out -6 from the x

You will get f(x)=12x

(Also do you go to RSM?)

Answer:

Mean = 30

standard Deviation = 2.74

Step-by-step explanation:

Formula

mean = np

Standard Deviation = $\sqrt{npq}$

from the question = 40

P = 75% or 0.75

q = 1 - p = 1 - 75% or 1 - 0.75

To find mean

mean = 40 x 0.75

= 30

For Standard Deviation (SD)

Standard Deviation = $\sqrt{npq}$

= $\sqrt{40 X 0.75 X 0.25$

= $\sqrt{7.5}$

:. Standard Deviation = 2.74

A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.

N76 [4]

The monthly payment amount is $860.25.

Step-by-step explanation:

Step 1; The bank offers an amount of $195,000 with an APR of 5.3%. This means that the family must pay 5.3% of the $195,000 every year for 30 years. To calculate we must determine how much 5.3% of $195,000 is. To do that we make 5.3% a fraction by dividing it by 100 and multiplying it with the amount.

5.3% of $195,000 = $\frac{5.3}{100}$ × $195,000 = 0.053 × $195,000 = $10,335 per year.

Payment owed for 30 years = Payment owed a year × 30

= $10,335 per year × 30 = $310,050 for 30 years.

Step 2; To find the monthly payments we need to know how many months are in a 30 year period. Months in 30 years = 30 × 12 months = 360 months. The monthly payment is, therefore, payment owed in 30 years divided by the months in that 30 year period.

Monthly payment = $10,335 / 360 = $ 861.25.

So the family must pay a monthly payment of $861.25 for 30 years.
