Suppose the Bainters purchase the $150,000.00 home with a 20% down payment, a 30-year mortgage, and an interest rate of 4.2%. An
Elden [556K]

Answer:

  $809.32

Step-by-step explanation:

The loan amount is 80% of $150,000, or $120,000. The monthly payment of principal and interest is $586.82.

The total annual expense for taxes and insurance is $1920 +750 = $2670, so the monthly expense is $2670/12 = $222.50.

Then the total of payments for mortgage and escrow will be ...

  $586.82 +222.50 = $809.32

__

The monthly P&I payment is given by ...

  A = P(i/12)/(1 -(1 +i/12)^(-12t)) . . . . . where i is the annual interest rate, t is the number of years, and P is the amount financed.

  A = $120,000(0.042/12)/(1 -(1 +0.042/12)^(-12·30)) ≈ $586.82

__

A spreadsheet or financial calculator can be useful for calculating payments, though the formula isn't difficult to use.

Find the area of the shaded region where a = -1.88 and b = 2.12. Note: the graph may not be drawn to scale. Write only a number
Igoryamba

Answer:

0.0471

Step-by-step explanation:

Here, we want to find the area of the shaded region.

The area of the shade region = 1- area of the unshaded region

The area of the unshaded region is as follows;

P(b) - P(a)

and that is;

P(-1.88<x<2.12) = 0.95294 from z table

So the area of the shaded region = 1-0.95294 =

0.04706 = 0.0471 to 4 d.p

Hazel wants to mix 12 pounds of her special blend coffee that will cost her $12.50 per pound. She uses Columbian and Sumatra cof
k0ka [10]
Let x be the amount of Columbian coffee in the mixture and y the amount of Sumatra coffee in the mixture, then
x + y = 1 . . . (1)
9.25x + 14.25y = 12.50 . . . (2)

(1) x 9.25 => 9.25x + 9.25y = 9.25 . . . (3)

(2) - (3) => 5y = 3.25 => y = 3.25/5 = 0.65

From (1), x + 0.65 = 1 => x = 1 - 0.65 = 0.35

1 pound of the mixture contains 0.35 Columbian coffee and 0.65 Sumatra coffee
Therefore, 12 pounds of the mixture will contain 0.35 x 12 = 4.2 pounds of Columbian coffee and 0.65 x 12 = 7.8 pounds of Sumatra coffee
