The Taylors have purchased a $320,000 house. They made an initial down payment of $20,000 and secured a mortgage with interest c
gogolik [260]
Part A: monthly payment

Initial loan after downpayment,  
P = 320000-20000= 300,000

Interest rate per month, 
i = 0.06/12= 0.005

Number of periods, 
n = 30*12= 360

Monthly payment, 
A = P*(i*(1+i)^n)/((1+i)^n-1)
= 300000(0.005(1.005)^360)/(1.005^360-1)
= 1798.65


Part B: Equities
Equity after y years
E(y) = what they have paid after deduction of interest
= Future value of monthly payments - cumulated interest of net loan
= A((1+i)^y-1)/i - P((1+i)^y-1)
= 1798.65(1.005^y-1)/.005 - 300000(1.005^y-1)
= (1798.65/.005-300000)(1.005^y-1)

Equity E
for y = 5 years = 60 months
    E(60) = (1798.65/.005-300000)(1.005^60-1) = 18846.17
for y = 10 years = 120 months
    E(120) = (1798.65/.005-300000)(1.005^120-1) = 45036.91
y = 20 years = 240 months
    E(240) = (1798.65/.005-300000)(1.005^240-1) = 132016.53

Check: equity after 30 years
y = 30 years = 360 months
    E(360) = (1798.65/.005-300000)(1.005^360-1) = 300000.00  .... correct.

5x+4y=8

-5x from both sides, you get 4y=-5x+8
then you divide the equation by 4.

y=-5/4x+2

10x-4y=46

-10x from both sides and you get -4y=-10x+46
divide the whole equation by -4 and you get y=5/2x + -23/2 .

Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficie
Mashcka [7]

Answer:

309 students

Step-by-step explanation:

Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficient in math, and 512 were found to be proficient in either reading or math. How many were proficient in both reading and math?

We solve the above question using the formula below:

Where R = Proficiency in reading

M = Proficiency in maths

n ( R ∪ M) = n(R) + n ( M) - n ( R ∩ M)

n ( R ∪ M) = 512 students

n(R) = 423

n ( M) = 398

n ( R ∩ M) = ??

Hence:

512 = 423 + 398 - n ( R ∩ M)

n ( R ∩ M) = 423 + 398 - 512

= 821 - 512

= 309

The number of people proficient in both reading and math [n ( R ∩ M)] = 309 students

Nuetrik [128]

Answer:

The answer is "0.0547".

Step-by-step explanation:

P(Correct) = 0.50\\\\n = 10\\\\x = 8

Using the binomial distribution:

\to P(x,n) = n_{C}_x \times p^x \times (1-p)^{(n-1)}\\\\\to P(x \geq 8) = 1 - P( \leq 7)

Calculating the excel formula:

=BINOM.DIST(7,10,0.50,TRUE)

\to P(x \geq 8) = 1 - 0.9453\\\\ \to P(x \geq 8) = 0.0547
