Answer:

18.81

Step-by-step explanation:

The correct option is a) (-7, 3) which is the midpoint of the segment.

To find the midpoint of a segment, we need to use the midpoint formula:

Midpoint = ( \((x1 + x2)/2 , (y1 + y2)/2\) )

The midpoint of a segment is the point that lies exactly halfway between the two endpoints of the segment.

It is calculated using the midpoint formula, which involves finding the average of the x-coordinates and y-coordinates of the endpoints.

Using the coordinates given in the diagram, we can substitute them into the formula:

Midpoint = ( (-9 + 5)/2 , (3 + 3)/2 )

Midpoint = ( (-4)/2 , 6/2 )

Midpoint = ( -2 , 3 )

However, it means that if we were to draw a line segment connecting (-9, 3) and (5, 3), the midpoint would be exactly in the middle of that line.

Step-by-step explanation:

Two samples can have the same mean but different standard deviations due to the spread of data around the mean. Standard deviation is a measure of how much the data values differ from the mean. The greater the deviation of the data points from the mean, the greater the standard deviation.

Two samples can have the same mean but different standard deviations because standard deviation is a measure of the spread of data around the mean. If the data values are tightly clustered around the mean, the standard deviation will be small. If the data values are spread out around the mean, the standard deviation will be large. Therefore, two samples can have the same mean but different standard deviations because the spread of data around the mean can be different for each sample.

Two samples can have the same mean but different standard deviations because the spread of data around the mean can be different for each sample. For example, consider two samples of test scores. Sample A has a mean score of 80 and a standard deviation of 5. Sample B has a mean score of 80 and a standard deviation of 10. The scores in Sample B have more variability than the scores in Sample A.In a bar graph, the means of the two samples can be represented by two bars with the same height. The standard deviations of the two samples can be represented by error bars on each bar. The error bars show the variability of the data in each sample. The length of the error bars for Sample B would be longer than the length of the error bars for Sample A.

Answer: it is the monthly fee

Step-by-step explanation: In y=3x+10 the y is the total amount he payed per month. The 3x is saying he payed $3 per visit (x) and slope, and the 10 is the monthly fee and y- int. He payed $10 at the start of each month.

The y-intercept of the graph is 10, which represents the monthly fee that Rich pays to the gym regardless of the number of visits.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
The given equation is, y = 3x + 10

This is in the form of a linear equation, where y represents the total cost per month and x represents the number of visits. The coefficient of x is 3, which represents the per-visit fee that Rich pays. The constant term is 10, which represents the monthly fee that Rich pays regardless of the number of visits.

The y-intercept of the graph of this equation is the value of y when x is equal to 0. Substituting x = 0 into the equation, we get,
y = 3(0) + 10

y = 10

Therefore, the y-intercept of the graph is 10, which represents the monthly fee that Rich pays to the gym regardless of the number of visits.

Therefore, the probability that more than 50% of the people in the sample are married is approximately 0.115 (rounded to three decimal places).

To solve this problem, we can use the normal approximation to the binomial distribution since the sample size is large (n = 1000) and the proportion of married persons (p) is not too close to 0 or 1.

The mean of the sample proportion can be calculated as:

μ = p = 0.482

The standard deviation of the sample proportion can be calculated as:

σ = sqrt((p * (1 - p)) / n) = sqrt((0.482 * (1 - 0.482)) / 1000) ≈ 0.015

To find the probability that more than 50% of the people in the sample are married, we need to calculate the z-score and find the area under the normal curve to the right of this z-score.

The z-score can be calculated as:

z = (x - μ) / σ = (0.5 - 0.482) / 0.015 ≈ 1.200

Using a standard normal distribution table or a calculator, we can find that the area to the right of z = 1.200 is approximately 0.1151.

The variable's range is calculated by taking its greatest observed value and subtracting its minimum observed value (minimum). Possible range or variational bounds: a variety of steel costs; a variety of styles; The scope or size of a method or action: perception. The maximum or anticipated range of a weapon's projectile. A list or set's range is the number between the lowest and maximum. Align all of the numbers before determining the region. Next, subtract (reduce) the lowest number from the greatest number. The solution includes the range of the list. The solution specifies the range of the list.

The range is 4.5, which implies that the difference between the data set's biggest and lowest values is 4.5. The range is 8 - 3.5 = 4.5 since the biggest number is 8 and the smallest value is 3.5.

The formula for the nth term of the sequence is: a_n = (2n + 4) / (2^(n-1))

To generate a formula for the nth term of the sequence, let's examine the pattern in the provided terms:

Term 1: 6/1

Term 2: 8/2

Term 3: 10/6

From the provided terms, we can observe that the numerator of each term is increasing by 2, and the denominator is increasing by a factor of 2 for each term.

We can express the numerator of the nth term as 6 + (n - 1) * 2, which simplifies to 6 + 2n - 2 = 2n + 4.

For the denominator, we can express it as 1 * 2^(n-1), which simplifies to 2^(n-1).

Therefore, the formula is:

a_n = (2n + 4) / (2^(n-1))

This formula will give you the value of the nth term based on the value of n.

Answer:  your equation is poorly written/wrong hence I used the equation below

answer :  $289156.63

Step-by-step explanation:

applying the formula to calculate monthly repayment of Mortgage

M = P [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]  -----  ( 1 )

M = Total monthly payment = 800 * 12 * 30 = $ 288,000

P = ?

r = 5.2% / 12 = 0.4%

n = 30 * 12 = 360 months

Back to equation 1

P = M / [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]

   = 288000 / [ 0.004 ( 1.004)^360 / (( 1.004)^360 ) - 1 ) ]

   = 288,000 / -0.996  =  - $289156.63 ( It has a negative value because It is a loan borrowed )

Borrowers can make more accurate comparisons between different loan options and understand the overall cost they will incur over the life of the loan.

In the given scenario, there are two banks offering 20-year, $210,000 mortgages at 4.4 percent interest. The banks charge a $3,100 loan application fee. However, there is a difference between the banks regarding the refundability of the application fee.

Insecurity Bank and Trust: This bank charges a $3,100 loan application fee, which is refundable if the loan application is denied. In this case, the fee is considered part of the loan rather than a separate fee.

I. M. Greedy and Sons Mortgage Bank: This bank also charges a $3,100 loan application fee, but it is nonrefundable, meaning it will not be returned if the loan application is rejected.

The disclosure law requires that any fees that will be refunded if the applicant is rejected must be included in calculating the Annual Percentage Rate (APR). This is because these fees are considered part of the loan amount and have an impact on the overall cost of borrowing.

On the other hand, nonrefundable fees like the one charged by I. M. Greedy and Sons Mortgage Bank are not required to be included in the APR calculation. This is because these fees are treated as separate costs that are not directly part of the loan.

When comparing mortgage offers and determining the true cost of borrowing, it is important to consider not only the interest rate but also any associated fees. By including refundable fees in the APR calculation, borrowers can make more accurate comparisons between different loan options and understand the overall cost they will incur over the life of the loan.

However, to find the slope of the perpendicular equation, you need to get the negative reciprocal of the slope!

For example, if the slope is 3 in the original equation, it would be - 1/3 in perpendicular equation.

We then substitute the given point for (x,y)!
