Answer:

The correct option is c. An amount equal to or greater than $25,000 but less than $36,000.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

Amazon Rafting just bought a new trailer. To pay for the trailer, the company took out a loan that requires Amazon Rafting to pay the bank a special payment of $8,700 in 5 years and also pay the bank regular payments of $4,100 each year forever. The interest rate on the loan is 14.3 percent per year and the first $4,100 yearly payment will be paid in one year from today. What was the price of the trailer?

a. An amount less than $14,000 or an amount equal to or greater than $62,000

b. An amount equal to or greater than $14,000 but less than $25,000

c. An amount equal to or greater than $25,000 but less than $36,000

d. An amount equal to or greater than $36,000 but less than $49,000

e. An amount equal to or greater than $49,000 but less than $62,000

The explanation of the answer is now provided as follows:

The price of the trailer can be calculated using the following formula:

Price of the trailer = (Special payment in 5 years / (1 + r)^n) + (Annual regular payment forever / r) .................... (1)

Where:

Special payment in 5 years = $8,700

r = Interest rate = 14.3% or 0.143

n = number of years = 5

Annual regular payment forever = $4,100

Substituting the values into equation (1), we have:

Price of the trailer = ($8,700 / (1 + 0.143)^5) + ($4,100 / 0.143)

Price of the trailer = ($8,700 / 1.95088267511394) + $28,671.33

Price of the trailer = $4,459.52 + $28,671.33

Price of the trailer = $33,130.85

Since the calculated price of the trailer is $33,130.85, the correct option is c. An amount equal to or greater than $25,000 but less than $36,000.

Answer: 292,320

​

Step-by-step explanation:

Find the increase, 1.5% of 288,000:

1.5/100 = 0.015

288,000 * 0.015=  4,320

Add the increase to the current population:

288,000+4,320=  292,320

Answer:

Area of the triangle = 31.25 yd²

Area of rectangle A = 50 yd²

Area of rectangle B = 48.75

Total Area of composite = 130 yd²

Step-by-step explanation:

✔️Area of the triangle = ½*b*h

b = 10 yd

h = 6.25 yd

Area of the triangle = ½*10*6.25 = 31.25 yd²

✔️Area of rectangle A = L*W

L = 10 yd

W = 7.5 - 2.5 = 5yd

Area of rectangle A = 10*5 = 50 yd²

✔️Area of rectangle B = L*W

L = 7.5 yd

W = 6.5 yd

Area of rectangle B = 7.5*6.5 = 48.75 yd²

✔️Total Area of Composite = 31.25 + 50 + 48.75 = 130 yd²

Answer:

5 liters!

Step-by-step explanation:

For every 4 students, there's 1 liter of water needed.

S = Students - L = Liters

4S = 1L

8S = 2L

12S = 3L

16S = 4L

20S = 5L

Answer:

37,500 and non recurring

Step-by-step explanation:

The Riley's will pay a total of $7,500 in costs for the closing costs and $30,000 down payment on their mortgage.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Rileys are buying a home that costs $250,000.

12% for a down payment

So, down payment is

12% of 250,000

= 12/100 ×250,000

= 12×2500

= $30,000

They are paying 3% in closing costs

3% of 250,000

= 3/100×250,000

= $7,500

Therefore, the Riley's will pay a total of $7,500 in costs for the closing costs and $30,000 down payment on their mortgage.

Answer:

1. c. 34%

2. b. 7.8 hours

Step-by-step explanation:

Empirical Rule:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Z-score:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

Mean of 6 hours, standard deviation of 1.5 hours.

1. Approximately what percent of people sleep between 6 and 7.5 hours per night?

6 hours = mean

7.5 hours = 6 + 1.5 = 1 standard deviation above the mean.

Approximately 68% of the measures are within 1 standard deviation of the mean. Since the normal distribution is symmetric, 34% are between one standard deviation below the mean and the mean, and 34% are between the mean(6 hours) and 1 standard deviation above the mean(7.5 hours). So the answer is 34%, given by option c.

2. If Aaron had a Z score of 1.2 how many hours did he sleep?

We have that [tex]Z = 1.2, \mu = 6, \sigma = 1.5[/tex]. We have to find X.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.2 = \frac{X - 6}{1.5}[/tex]

[tex]X - 6 = 1.2*1.5[/tex]

[tex]X = 7.8[/tex]

So option b.

Given:

The equation is

[tex]P=-3-4L-6[/tex]

To find:

The formula for L.

Solution:

We have,

[tex]P=-3-4L-6[/tex]

It can be written as

[tex]P=(-3-6)-4L[/tex]

[tex]P=-9-4L[/tex]

We need to isolate variable L.

Adding 6 on both sides, we get

[tex]P+6=-4L[/tex]

Dividing both sides by -4, we get

[tex]\dfrac{P+6}{-4}=L[/tex]

[tex]\dfrac{P}{-4}+\dfrac{6}{-4}=L[/tex]

[tex]-\dfrac{P}{4}-1.5=L[/tex]

Therefore, the required value of L in terms of P is [tex]L=-\dfrac{P}{4}-1.5[/tex].

Answer:

A.) Coefficient

Step-by-step explanation:

While it is a term, it says which word best describes it, so it would better be classified as a coefficient since coefficients have variables attached to them

Answer:

x=7

Step-by-step explanation:

The solution to the equation is x = 7.

We have,

Equation:

3x - 5 = 16

Add 5 on both sides.

3x - 5 + 5 = 16 + 5

3x = 21

Divide 3 on both sides.

x = 21/3

x = 7

Thus,

The solution to the equation is x = 7.
