Given that;

the following chart to explain how the interest rate affects the total cost of the loan.

Now, In a part of the mortgage payment is dedicated to repayment of the principal balance.

And, explain that Loans are structured so the amount of principal returned to the borrower starts low and increases with each mortgage payment.

Then,  The payments in the first years are applied more to interest than principal, while the payments are in the final years.

In our mortgage $100,000, The principal is $100,000.

This happens because the interest rate attached affects larger First figures will more than smaller ones.

6.47% of $5,000 is $323.5 which is less than = 10.8% of $5,000 which is $540 .

now,(calculating the cost of a loan is more this shows the effect as well).

When compounded over time, this is difference will be even more and thus shows that larger principals cause larger total costs.

The simplified factor of the given expression 18x³y³ − 6x²y is given by option C. 6x²y(3xy² − 1).

Expression is equal to,

18x³y³ − 6x²y

Factor out the greatest common factor of the two terms 18x³y³ and 6x²y.

Greatest common factor of 18 and 6 is 6.

Greatest common factor of x³y³ and x²y is equal to x²y.

using both results we have,

Greatest common factor ( 18x³y³ and 6x²y ) = 6x²y

Now take out the greatest common factor and simplify the expression, we get,

= 18x³y³ − 6x²y

= 6x²y(3xy² − 1)

The term "average" is commonly used in mathematics, statistics, and other fields to describe a central value of a set of data. In general, there are three types of averages: the mean, the median, and the mode.

The mean is the sum of all the values in a set divided by the number of values. It is commonly used to describe the average score of a group of students, the average temperature of a region, or the average income of a population. The median is the middle value in a set of data when it is arranged in order.

Using proportion, the length of shadow of Eiffel tower with antenna is 797.25 feet.

The length of Me = 6 feet

The length of my shadow = 4 feet 6 inches = 4.5 feet [Since 1 feet = 12 inches]

So the ratio of the shadow to actual length = 4.5/6 = 3/4

By proportion we know that the ratio of shadow to actual length any object at a same time is similar.

Let the length of shadow of Eiffel tower be x feet.

The length of Eiffel tower with antenna is = 1063 feet.

According to proportion we get,

x/1063 = 3/4

x = (3/4)*1063 = 797.25 feet.

Answer:

Step-by-step explanation:

The system of linear equations is:

y = -1/4 x + 1

y = -2x - 1

To find the solution to the system, we need to find the point where the two lines intersect. We can do this by graphing the two lines and finding their point of intersection, or by solving the system of equations algebraically.

Using the second method, we can substitute the first equation into the second equation for y:

-1/4 x + 1 = -2x - 1

Simplifying and solving for x, we get:

15/8 x = 2

x = 16/15

Substituting this value of x into the first equation to solve for y, we get:

y = -1/4 (16/15) + 1

y = 19/15

So the solution to the system is (16/15, 19/15).

Looking at the graphs, we can see that only the first option has a point of intersection that matches the solution we found algebraically. Therefore, the graph that shows the solution to the system of linear equations is a coordinate grid with one line that passes through the points 0,1 and 4,0 and another line that passes through the points 0,-1 and 1,-3.

The median of a data set is the middle number. To find this value, you'll need to order your data set from smallest to largest and then cross off values equally from each end until you reach the middle. In the case there are two numbers in the middle, you will find the mean/average of those two numbers.

Answer: C. 16

Hope this helps!

Answer:

C and D both represent angle relationships in the figure.

C represents the relationship between the angles labeled x, y, and z. We know that the sum of the angles in a triangle is 180 degrees, so we can set 6x+14 (angle x), 33 (angle y), and 180-(7x-9) (angle z) equal to 180 and solve for x.

D represents the relationship between the angles labeled w, x, y, and z. We know that the sum of the angles in a quadrilateral is 360 degrees, so we can set 33+(5x-10)+(7x-9)+w equal to 360 and solve for x.

The answer is approximately 45.82%, which is closest to 41.2% which is calculated using the binomial distribution formula.

To solve this problem, we can use the binomial distribution formula, which is:

[tex]P(X ≤ k) = Σ^n_i=0 (n choose i) p^i (1-p)^(n-i)[/tex]

Where:

X= number of senior adults who wear glasses for driving

k= maximum number of senior adults who wear glasses for driving that we're interested in (in this case, 16)

total number of senior adults in the group (in this case, 20)

p =probability that a senior adult wears glasses for driving (in this case, 0.81)

We want to find P(X ≤ 16), which represents the probability that no more than 16 senior adults wear glasses for driving.

Using the formula above, we get:

[tex]P(X ≤ 16) = Σ^20_i=0 (20 choose i) 0.81^i (1-0.81)^(20-i)[/tex]

Calculating this sum exactly can be quite tedious, but we can use a normal approximation to get an estimate.

Utilizing the mean (np = 20*0.81 = 16.2) and the standard deviation (sqrt(np(1-p)) = 1.94) of the binomial dissemination, able to surmise the likelihood utilizing the ordinary dissemination as taken after:

P(X ≤ 16) ≈ P(Z ≤ (16 - 16.2)/1.94) 

Where Z =standard normal random variable.

Using a standard normal distribution table or a calculator, we can find that:

P(Z ≤ (16 - 16.2)/1.94) ≈ P(Z ≤ -0.103)

≈ 0.4582

hence, the answer is approximately 45.82%, which is closest to 41.2%.

In a bag, there are 14 red, 11 blue and 5 green sweets. one sweet is picked out of the bag. Therefore, the probability of picking a sweet that is neither red nor blue is 1 - 5/6 or 1/6.



In the bag, there are 14 red, 11 blue, and 5 green sweets, totaling 30 sweets. We want to find the probability of picking a sweet that is neither red nor blue, which means we are looking for the probability of picking a green sweet.

To calculate the probability, use the following formula:

Probability = (Number of desired outcomes) / (Total number of possible outcomes)

In this case, the number of desired outcomes is the number of green sweets, which is 5. The total number of possible outcomes is the total number of sweets in the bag, which is 30.

So, the probability of picking a green sweet is:

Probability = 5/30

In Mathematics, a parallelogram is a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.

In this context, we can reasonably infer and logically deduce that this parallelogram has both pairs of opposite sides being parallel to each other and the opposite angles (vertical angles) are equal and congruent:

m∠1 = m∠3

m∠2 = m∠4

5x - 23 = 3x - 5

5x - 3x = 23 - 5

2x = 18

x = 9.

m∠2 = 5(9) - 23 = 22°

m∠1 + m∠2 + m∠3 + m∠4 = 360

Answer:

x = 7 and x = -1/3

Step-by-step explanation:

To solve the quadratic equation 3x^2 - 20x - 7 = 0, we can use the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation.

In this case, a = 3, b = -20, and c = -7. Substituting into the quadratic formula, we get:

x = (-(-20) ± sqrt((-20)^2 - 4(3)(-7))) / 2(3)

Simplifying the expression inside the square root:

x = (20 ± sqrt(400 + 84)) / 6

x = (20 ± sqrt(484)) / 6

x = (20 ± 22) / 6

So, we have two solutions:

x = (20 + 22) / 6 = 7

x = (20 - 22) / 6 = -1/3

Therefore, the solutions to the quadratic equation 3x^2 - 20x - 7 = 0 are x = 7 and x = -1/3.
