Answer: 21

Step-by-step explanation:

Answer: $4,580

Step-by-step explanation:

First, we need to calculate the monthly payment for the 15-year, fixed-rate loan at the original rate of 5.05%. We can use the formula for the monthly payment of a mortgage loan:

P = L[c(1 + c)^n]/[(1 + c)^n - 1],

where P is the monthly payment, L is the loan amount, c is the monthly interest rate (which is the annual interest rate divided by 12), and n is the total number of payments (which is the number of years multiplied by 12).

Plugging in the given values, we get:

L = $137,000

c = 0.0505/12 = 0.0042083 (rounded to 7 decimal places)

n = 15 x 12 = 180

P = $1,071.18

Next, we need to calculate the monthly payment at the lower rate of 4.81% if the buyers purchase four points. Each point costs 1% of the loan amount, so four points will cost 4% of the loan amount.

The new rate after purchasing four points is:

5.05% - 0.24% = 4.81%

The new loan amount after purchasing four points is:

$137,000 - (4% x $137,000) = $131,920

Using the same formula for the monthly payment, but with the new values for the loan amount and monthly interest rate, we get:

L = $131,920

c = 0.0481/12 = 0.0040083 (rounded to 7 decimal places)

n = 15 x 12 = 180

P = $1,030.98

The monthly savings due to the lower interest rate is:

$1,071.18 - $1,030.98 = $40.20

To calculate the cost of the four points, we need to divide the upfront cost of the points by the monthly savings:

Cost of four points = ($40.20 x 180)/0.0024 = $3,015

Therefore, the cost of the four points is $3,015, which is closest to $4,580.

The four points that the homebuyers are purchasing to lower their rate from 5.05% to 4.81% will cost them D. $5,480.

The points purchased for loans are charges that the borrower pays upfront to lower their interest rates.

Each point equals a percentage of the loan amount.

For example, four points on a $137,000 loan are 4 percent of the loan amount, or $5,480.

The loan amount for the purchase of the condominium = $137,000

Fixed interest rate = 5.05%

Loan period = 15 years

Loan option rate = 4.81%

Hence, Four points =  $137,000 x 4%

                              = $5,480

The correct option about the two data set's distribution is B) The distributions are somewhat similar.

Given that,

For data set 1,

Mean = 54 and MAD = 4

For data set 2,

Mean = 60 and MAD = 2

Means to MAD ratio = (60 - 54) / (2 - 4) = 6 / -2 = -3

So means to MAD ratio is -3, not 3.

Now, it is clear that the distributions are not fully similar.

Answer: y + 6 = -4 (x+2)

Step-by-step explanation:

The Mean Absolute Deviation of the given data set, 58, 38, 54, 48, 26, 36 is 10

From the question, we are to calculate the mean absolute deviation of the given data set

The given data set is:

58, 38, 54, 48, 26, 36

First, we will determine the mean of numbers

Mean = (58 + 38 + 54 + 48 + 26 + 36) / 6

Mean = 260 / 6

Mean = 43.33

To calculate the MAD, we will determine the absolute deviation of each data from the mean

|58 - 43.33| = 14.67

|38 - 43.33| = 5.33

|54 - 43.33| = 10.67

|48 - 43.33| = 4.67

|26 - 43.33| = 17.33

|36 - 43.33| = 7.33

Now, we will calculate the mean of the absolute deviations

MAD = (14.67 + 5.33 + 10.67 + 4.67 + 17.33 + 7.33) / 6

MAD = 60/6

MAD = 10

Answer: The monthly payment for the sailboat is $348.14, and the total interest paid over the 12-year period is $13,080.16.

Step-by-step explanation: To calculate the monthly payment and interest for the sailboat, we can use the formula for the present value of an annuity due:

PV = PMT * [(1 - (1 + r)^(-n)) / r] * (1 + r)

where PV is the present value, PMT is the monthly payment, r is the monthly interest rate, and n is the total number of payments.

First, we need to calculate the present value of the sailboat after the down payment:

PV = $35,000 - (0.2 * $35,000) = $28,000

Next, we can plug in the values and solve for PMT:

$28,000 = PMT * [(1 - (1 + 0.0875/12)^(-12*12)) / (0.0875/12)] * (1 + 0.0875/12)

Simplifying this equation, we get:

PMT = $348.14

Therefore, your monthly payment for the sailboat would be $348.14.

To calculate the total interest paid, we can multiply the monthly payment by the total number of payments (12 years * 12 months/year = 144 payments) and subtract the principal amount:

Total Interest = (PMT * n) - PV

Total Interest = ($348.14 * 144) - $28,000

Total Interest = $13,080.16

Therefore, you would pay a total of $13,080.16 in interest over the 12-year period.

The probability that the randomly selected person attending the concert is an adult or has purchased the ticket in advance is 188/250.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given a table which shows when the tickets for a concert are sold and the types of tickets that are sold.

The probability of A or B can be calculated as,

P(A or B) = P(A) + P(B) - P(A and B)

Let A denote the people is an adult.

Let B denote the people who has purchased the ticket in advance.

P(A) = 148/250

P(B) = 140/250

P(A and B) = 100/250

Probability that a randomly selected person attending the concert is an adult or has purchased the ticket in advance is,

P(A or B) = 148/250 + 140/250 - 100/250

              = 288/250 - 100/250

              = 188/250

The class width is 0.3877.

In order to analyze data, it is often helpful to group it into categories, or intervals, and then determine how frequently each interval occurs. This process is known as frequency distribution.

To calculate the class width, you need to determine the range of each interval. The range is the difference between the upper and lower limits of the interval. For example, the first interval is 160-179, so the range is 179-160=19.

In mathematical terms, the formula for class width is:

Class Width = (Range of all intervals) / (Number of intervals)

In your case, the range of the intervals are:

19, 19, 19, 19, and 19

And the number of intervals is:

53 + 24 + 93 + 27 + 48 = 245

So, the class width can be calculated as follows:

Class Width = (19+19+19+19+19) / 245

Class Width = 95 / 245

The number of stamps that Jessica and Bonita have altogether if the percent increase in stamps with Bonita is 15% more is 2150.

Given that,

Bonita has 15 percent more stamps than Jessica.

Let x be the number of stamps that Jessica has.

Then,

Number of stamps that Bonita has = x + 150

x + 150 = x + 15% of x

x + 150 = x + (0.15)x

x + 150 = 1.15x

0.15x = 150

x = 1000

Hence the number of stamps that Jessica has = 1000

Number of stamps that Bonita has = 1150

Total number of stamps = 1000 + 1150 = 2150

The time it will take for the money in the account to reach $4,000 is about 15.407 years.

To solve for the number of years it takes for the amount in the account to reach $4,000, we need to solve the equation:

[tex]4000 = 2000e^{0.045t[/tex]

Dividing both sides by 2000, we get:

To solve for t, we can take the natural logarithm of both sides:

[tex]ln 2 = ln e^{(0.045t)[/tex]

Using the property that ln [tex]e^x = x[/tex], we can simplify this to:

[tex]ln 2 = 0.045t[/tex]

Dividing both sides by 0.045, we get:

t = (ln 2)/0.045

Property of logarithms: The property of logarithms that we used in this problem states that if loga(b) ≥ loga(c), then b ≥ c. This property is true for any base of the logarithm. Note that the inequality symbol flips when you move from the logarithmic expression to the exponential expression.

Solving linear inequalities: To solve a linear inequality like ax + b > c, you need to isolate the variable on one side of the inequality. This involves adding or subtracting terms and possibly multiplying or dividing by constants. You need to be careful when multiplying or dividing by a negative number, as this flips the inequality symbol.

Domain restrictions: When solving logarithmic inequalities, you need to make sure that the argument of the logarithm is positive. This means that the expression inside the logarithm cannot be zero or negative. You need to check for domain restrictions and make sure that any values that make the argument zero or negative are not included in the solution.

Check the solution: After solving the inequality, it's always a good idea to check the solution to make sure that it satisfies the original inequality. You can plug in the solution to the inequality and make sure that both sides of the inequality are still true. If not, you may have made a mistake in solving the inequality.

To solve log2(7x-3) ≥ log2(x+12), you can start by using the fact that if loga(b) ≥ loga(c), then b ≥ c:

Using this property, you can rewrite the inequality as:

7x - 3 ≥ x + 12

Simplifying the inequality by subtracting x and adding 3 from both sides, you get:

6x ≥ 15

Dividing both sides of the inequality by 6, you get:

x ≥ 2.5

Therefore, the solution to the inequality is x ≥ 2.5 which is option C.

Note that when you use the property of logarithms to simplify an inequality, you need to make sure that the argument of the logarithm is positive. In this case, both arguments are positive as long as x > 3/7 and x > -12, respectively. However, these conditions are automatically satisfied when x ≥ 2.5, so there is no need to check them separately.

A combination is a technique for calculating the number of alternative arrangements in a set of objects where the order of the selection is irrelevant.

Given this,

Mrs. Smith wants to arrange six activity tables side by side in her classroom.

After aligning all six tables in a straight line, we can use the factorial function to compute the product of all positive integers up to a specified value. We could write:

6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

As a result, there are 720 different ways to arrange all six tables in a row.

And, to select four of the six tables, we can use the combination function, which computes the number of ways to select k things from n different items, regardless of their order. We could write:

⁶C₄ = 6! / (4! x 2!)

= (6 x 5 x 4 x 3 × 2 × 1) / [(4 x 3 x 2 x 1) × (2 × 1)]

I'm assuming you mean y = [3x+5], wherein the brackets signify the biggest integer function (also known as the floor function).

What exactly are function and example?

A function was a type of rule that produces one output for one input. Alex Federspiel provided the image. y=x2 is an example of this. If you enter something for x, you will only get a single result for y. Because x represents the input value, we can say as y represents a function of x.

To graph this formula, we must plot points which satisfy the conditions, where y is the largest integer that is equal or less than to 3x+5.

Let's begin by examining some specific x values:

When x equals -2, y equals [3(-2)+5]. = [-1] = -1

When x equals -1.5, y equals [3(-1.5)+5]. = [-0.5] = -1

When x equals -1, y equals [3(-1)+5]. = [2] = 2

y = [3(-0.5)+5] for x = -0.5. = [3.5] = 3

When x = 0, y equals [3(0)+5]. = [5] = 5

When x equals 0.5, y equals [3(0.5)+5]. = [6.5] = 6

When x equals 1, y equals [3(1)+5]. = [8] = 8

When x equals 1.5, y equals [3(1.5)+5]. = [9.5] = 9

When x equals 2, y equals [3(2)+5]. = [11] = 11
