Aphrodite took out a 30-year loan from her bank for $170,000 at an APR of

horsena [70]

Answer:

A. $3246.74

Step-by-step explanation:

The monthly payment can be found from the amortization formula.

A = P(r/n)/(1 -(1 +r/n)^(-nt))

where P is the principal amount, r is the annual rate compounded n times per year for t years.

Filling in the values, we compute the monthly payment to be ...

A = $170,000(.072/12)/(1 -(1 +.072/12)^(-12·30)) = $1153.94

The remaining balance after t years will be ...

B = P(1 +r/n)^(nt) -A((1 +r/n)^(nt) -1)/(r/n)

For the given initial principal and the computed payment, after 18 years, the balance will be ...

B = $170000(1 +.072/12)^(12·18) -$1153.94((1 +.072/12)^(12·18) -1)/(.072/12)

B = $111,054.71

The prepayment penalty appears to be ...

(r/2)(0.80B) = (.072/2)(0.80)($111,054.71) = $3,198.38

The closest listed answer choice is ...

A. $3246.74

A stick is broken into two pieces, at a uniformly random break point. Find the CDF and average of the length of the longer piece

Oksanka [162]

Answer:

P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1

Step-by-step explanation:

let assume that stick has length 1.Random variable L that make length of a longer piece and random variable U that mark point .See that L < l means that

U≤ l and 1-U ≤l

P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1

this means 1-l≤U≤l

so we have

if we have L [1/2,1]

then apply the formula we have E(L)=3/4

The price for a gallon of whole milk has increased from 2006 to 2008. from 2006 to 2007, the cost of whole milk increased by app

valkas [14]

You have the starting price of $1.99. To get the increased price, divide 1.99 by .56 (.56 is the decimal form of 56%). You would get $3.55. This is for the year 2007. So for 2008, divide 3.55 by .42. The answer is $8.45. You can check the answers by multiplying the answers you go the the percentage. Ex. 8.45* .42=3.55 (rounded)
