Answer:

$1,955.86

Step-by-step explanation:

We have to use the MS Excel to solve this question

PV = -300000

FV = 0    

I = 6.8%/12 = 0.5667%    

N = 30*12 = 360

Monthly payment = PMT(-PV, FV, I, N)

Monthly payment = PMT(-300,000, 0, 0.5667%, 360)

Monthly payment = $1955.8555499

Monthly payment = $1,955.86

So, her monthly payment is $1,955.86.

Answer:

f(x-4) = x²-8x + 17

f(x-4)-f(-4) = x²-8x

Step-by-step explanation:

Given the function:

f(x) = x^2+1

f(x-4) = (x-4)^2+1

f(x-4 ) = x² - 8x + 16 + 1

f(x-4) = x²-8x + 17

For f(x-4)-f(-4)

f(-4) = (-4)²+1

f(-4) = 16+1

f(-4) = 17

f(x-4)-f(-4) = x²-8x + 17 - 17

f(x-4)-f(-4) = x²-8x

Answer:

x = 2.2

Step-by-step explanation:

2(x+4)+6 = 12x-8

Use distribution property

2x+8+6 = 12x-8

Combine like terms

2x+14 = 12x-8

Subtract 14 from both sides

2x = 12x-22

Subtract 12x from both sides

-10x = -22

Divide both sides by negative 10

x = 2.2 or x = 11/5 in fractions.

Answer:

Step-by-step explanation:

Answer:

The answer is 4 \sqrt{7}.

Step-by-step explanation:

The formula is a\sqrt{x} + b\sqrt{x} = (a+b)\sqrt{x}, but if you don't understand it, here's an easier way to think about it.

You can think of \sqrt{7} as x (or any other variable). Now, the equation is 3x + x. If you've ever done algebra, (you probably have if square roots popped up on your homework) you know that this equals to 4x. Now, replace the x with \sqrt{7}, because we already decided that those two were equal. Therefore, the answer is

4 \sqrt{7}.

Answer:

The n-th term of this sequence is 3(-2)^(n-1)

Step-by-step explanation:

Term 1 = 3 = 3 X 1 =. 3(-2)^0

Term 2 = -6 = 3 X (-2) = 3(-2)^1

Term 3 = 12 = 3 X (-2) X (-2) = 3(-2)^2

…

The first term is 3, and every subsequent term is the previous term multiplied by -2.

Answer:

x=18

Step-by-step explanation:

let the number =x

then

x²-124=200

x²=200+124

x²=324

x=18

Answer:

x=18

Step-by-step explanation:

number = x

x^2 - 124 = 200

x^2 = 200 +124

x^2 = 324

(square root both sides)

x = 18

Answer:

p = 0.259264214

Step-by-step explanation:

26 - 7 = 19 with good brakes

Probability of picking 4 with good brakes

p = 19/26 * 18/25 * 17/24 * 16/23

p = 0.259264214

The probability that all the randomly chosen cars have good brakes is approximately 0.169 or 16.9%.

To calculate the probability that all the randomly chosen cars have good brakes, we need to consider the number of cars with good brakes and the total number of cars.

Total number of cars assembled: 26

Number of cars with bad brakes: 7

To calculate the probability, we can use the concept of combinations.

The number of ways to select 4 cars out of the remaining 26-7 = 19 cars with good brakes is given by the combination formula:

C(n, r) = n! / (r! * (n-r)!)

where n is the total number of cars with good brakes and r is the number of cars to be randomly selected.

In this case, n = 19 and r = 4.

The total number of ways to select 4 cars from the total pool of 26 cars is given by the combination formula:

C(26, 4) = 26! / (4! * (26-4)!)

Now, we calculate the probability that all the randomly chosen cars have good brakes:

Probability = (Number of favorable outcomes) / (Number of total outcomes)

Number of favorable outcomes = C(19, 4)

Number of total outcomes = C(26, 4)

Probability = C(19, 4) / C(26, 4)

Using a calculator, we can compute these combinations and evaluate the probability:

Probability ≈ 0.169

Therefore, the probability that all the randomly chosen cars have good brakes is approximately 0.169 or 16.9%.
