Find the slope of the line that passes through the pair of points. (4, 8), (8, 11)

Answers

Answer 1
Hey there! :) 

We're given the points : (4, 8) & (8, 11)

Plug these into the slope equation, which is : m = (y₂-y₁) / (x₂-x₁)

m = (11 - 8) / (8 - 4)

Simplify.

m = 3/4

So, our slope is 3/4!

Vanessa can afford a $1405-per-month house loan payment. If she is being offered a 20-year house loan with an APR of 4.8%, compounded monthly, which of these expressions represents the value of the most money she can borrow?

Answers

The correct option is A.

Vanessa can borrow approximately $6255.57, represented by option A: [tex]$\frac{(\$ 1405)\left((1+0.004)^{240}-1\right)}{(0.004)(1+0.004)^{240}}$[/tex].

To determine the value of the most money Vanessa can borrow with a monthly payment of $1405 for a 20-year house loan with an APR of 4.8%, compounded monthly, we can use the formula for the monthly payment of a mortgage:

[tex]\[P = \frac{M}{\frac{r}{12} \left(1 - \left(1 + \frac{r}{12}\right)^{-nt}\right)}\][/tex]

Where:

P = Principal amount (the amount she can borrow)

M = Monthly payment ($1405)

r = Monthly interest rate (APR divided by 12, or 0.048/12)

n = Number of times the interest is compounded per year (12 for monthly)

t = Number of years (20)

Now, let's plug in the values and solve for P:

[tex]\[P = \frac{1405}{\frac{0.004}{12} \left(1 - \left(1 + \frac{0.004}{12}\right)^{-12*20}\right)}\][/tex]

Let's calculate the exponent and simplify:

[tex]\[P = \frac{1405}{\frac{0.004}{12} \left(1 - \left(1 + \frac{0.004}{12}\right)^{-240}\right)}\][/tex]

Now, we can simplify the monthly interest rate:

[tex]\[P = \frac{1405}{\frac{0.004}{12} \left(1 - \left(1.000333333\right)^{-240}\right)}\][/tex]

[tex]\[P = \frac{1405}{0.333333 \left(1 - 0.328624967\right)}\][/tex]

Now, let's calculate the value inside the parentheses:

[tex]\[P = \frac{1405}{0.333333 \times 0.671375033}\][/tex]

[tex]\[P \approx \frac{1405}{0.22487499}\][/tex]

Now, calculate P:

P ≈ 6255.57

So, Vanessa can borrow approximately $6255.57.

The correct expression that represents the value of the most money she can borrow is:

A. [tex]$\frac{(\$ 1405)\left((1+0.004)^{240}-1\right)}{(0.004)(1+0.004)^{240}}$[/tex]

The complete question is here:

Vanessa can afford a [tex]$\$ 1405$[/tex]-per-month house loan payment. If she is being offered a 20-year house loan with an APR of [tex]$4.8 \%$[/tex], compounded monthly, which of these expressions represents the value of the most money she can borrow?

A. [tex]$\frac{(\$ 1405)\left((1+0.004)^{240}-1\right)}{(0.004)(1+0.004)^{240}}$[/tex]

B. [tex]$\frac{(\$ 1405)\left((1-0.048)^{240}-1\right.}{(0.048)(1+0.048)^{249}}$[/tex]

C. [tex]$\frac{(\$ 1405)\left((1-0.004)^{200}-1\right)}{(0.004)(1+0.004)^{240}}$[/tex]

D. [tex]$\frac{(51405)\left((1+0.048)^{200}-1\right)}{(0.048)(1+0.048)^{240}}$[/tex].

Using the formula for monthly loan payment, we find Vanessa can borrow up to $220,000 with a 20-year loan at 4.8% APR.

To find the maximum amount Vanessa can borrow, we can use the formula for the monthly payment of a loan:

[tex]\[ P = \frac{A \times r}{1 - (1 + r)^{-n}} \][/tex]

Where:

-  P  = monthly payment

-  A = loan amount (the value we want to find)

-  r  = monthly interest rate (APR divided by 12)

-  n  = total number of payments (number of years multiplied by 12)

Given:

- Monthly payment ( P) = $1405

- APR ( r ) = 4.8% = 0.048

- Loan term = 20 years

First, we calculate r :

[tex]\[ r = \frac{4.8}{100 \times 12} = 0.004 \][/tex]

Then, calculate n:

[tex]\[ n = 20 \times 12 = 240 \][/tex]

Now, plug the values into the formula and solve for A:

[tex]\[ 1405 = \frac{A \times 0.004}{1 - (1 + 0.004)^{-240}} \][/tex]

Solve for A:

[tex]\[ A = \frac{1405 \times (1 - (1 + 0.004)^{-240})}{0.004} \][/tex]

[tex]\[ A \approx \$220,000 \][/tex]

So, Vanessa can borrow a maximum of $220,000.

Answers

y₁ = 420 + 72x

y₁ = y₂
∴ 420 + 72x = 24x² +180
∴ 24x² - 72x - 240 = 0
∴ x² - 3x -10 = 0
∴ ( x + 2)( x - 5 ) = 0
∴ x = -2 (Unacceptable)    OR    x = 5

If 30 fair dice are rolled find the approximate probability that the average number ofo dots is between 2 and 4

Answers

The probability that the average number of dots is between 2 and 4 when rolling 30 fair dice is 0.9441.

what is probability?

Probability is the branch of mathematics that deals with the study of random events or phenomena. It involves the quantification of uncertainty and the measurement of the likelihood of occurrence of an event.

The average number of dots on a fair die is

= (1+2+3+4+5+6)/6

= 3.5.

We can model the sum of the numbers on the 30 dice as a normal distribution with mean

= (30)(3.5) = 105

and, standard deviation √(30)(35/12) ≈ 9.13.

Let X be the sum of the numbers on the 30 dice, and let Y be the average number of dots. Then Y = X/30.

We want to find P(2 ≤ Y ≤ 4). This is equivalent to P(60 ≤ X ≤ 120), since Y = X/30.

Using the normal distribution, we can standardize X to get:

Z = (X - 105) / 9.13

Then we can compute the probability as:

P(60 ≤ X ≤ 120)

= P[(60 - 105) / 9.13 ≤ Z ≤ (120 - 105) / 9.13]

≈ P(-4.93 ≤ Z ≤ 1.64)

Using a standard normal distribution table or calculator, we can find that P(-4.93 ≤ Z ≤ 1.64) ≈ 0.9441.

Therefore, the approximate probability that the average number of dots is between 2 and 4 when rolling 30 fair dice is 0.9441.

if Andy's home is worth 260,000, what is his coverage for personal property if insurance covers 50 percent?

Answers

[tex] \frac{50*260000}{100}=130000[/tex]

Answer:

Amount covered by insurance = 130000

Step-by-step explanation:

Cost of Andy's home = 260000

Percentage covered by insurance = 50%

Amount covered by insurance = 50% of Cost of Andy's home

                                                   = 50% of 260000

                                                   = 0.50 * 260000         [50% written as a decimal is 0.50]

                                                   = 130000
