Describe how to calculate each of the measures of central tendencies: mean, median, and mode. Be sure to include one description for each.

Answers

Answer 1

The mean is easy to calculate. Simply add all of the values together and divide by the number of observations in your dataset.

The median is the value in the middle of a list that is ordered from smallest to largest.

The mode value appears the most

How do you calculate the mean?

The mean, median, and mode are the three most common measures of central tendency. The most common value is the mode. In an ordered data set, the median is the number in the middle. The mean is calculated by taking the sum of all values and dividing it by the total number of values.

The mean is the arithmetic average, and it is probably the most familiar measure of central tendency.  The mean calculation takes into account all of the values in the data.

Let's assume we've the numbers 2, 5, and 5. The mean will be:

= (2 + 5 + 5) / 3

= 12/3

= 4

The median is 5 and the mode is also 5. The mode is the number that occurs most.

Suppose that a famer planned to borrow $5,400 from the bank and repay the loan at the end of the year. The interest rate at the bank is 7.36% compounded annually.
(i) Calculate the amount of interest paid to the Iron Bank.
(ii) Calculate the effective interest rate at the Iron Bank.
(i) $397.25
(ii) 7.36%

Answers

For the given principal amount $5,400 borrowed by a farmer from the bank at the rate of interest 7.36% compounded annually for the time period of 1 year then the amount of interest paid to the bank is equal to $397.44 and the effective interest rate is equal to 7.36%.

As given in the question,

Principal amount borrowed by a farmer from the bank 'P' = $5,400

Rate of interest compounded annually 'r' = 7.36%

Time period 'n' = 1 year

Amount = P [ 1 + (r/100) ]ⁿ

             = 5400 [ 1 + (7.36/100) ]¹

             = 5400 [ (100 + 7.36)/100]

             = 54 × 107.36

             = 5797.44

Amount of Interest paid to the bank = Amount - Principal amount

                                                            = 5797.44 - 5400

                                                            = $397.44

x = number of times compounding occurs in one year.

Here 'x' = 1

Effective Interest rate = [ 1 + (r/x) ]ˣ -1

                                    = [ 1 + ( 7.36%/1)]¹ -1

                                    = 1 + 7.36% - 1

                                    = 7.36%

Therefore, for the given principal amount $5,400 borrowed by a farmer from the bank at the rate of interest 7.36% compounded annually for the time period of 1 year then the amount of interest paid to the bank is equal to $397.44 and the effective interest rate is equal to 7.36%.

What is the solution to this system of linear equations yx 6 y x =- 10?.

Answers

The solution to this system of linear equations y - x = 6, y + x = - 10 is (-8, -2).

What is system of linear equations?

The set of two or more linear equations containing the same variables is known as a system of linear equations in mathematics. In this case, linear equations are first-order equations, where the maximum power of the variable is 1. One, two, or three variables may be present in a linear equation.

Given that;

Y - x = 6

Y + x = -10

Let's equalize the two equations as they are both equal to y;

x + 6 = - x - 10

By further calculation

x + x = - 10 - 6

2x = - 16

Divide both sides by 2

x = -8

The value of x should be replaced in either equation;

y - x = 6

y - (-8) = 6

So we get

y + 8 = 6

y = 6 - 8

y = - 2

Therefore, the solution to this system of linear equations y - x = 6, y + x = - 10 is (-8, -2).

What is loan interest?

The cost of borrowing money from a lender is interest. That implies that you won't just return the borrowed funds. The interest on the loan will be added to the amount you repay. Different strategies are used by lenders to assess interest.

The interest on student loan is deductible upto $2500.

This amount starts reducing once the MAGI reaches the Phase out limit.

The phase out starts at $140000 and ends at $170000

Maximum deduction is $2500 or actual whichever is lower,

The deduction of $2500 will reduce here by

2500 * (MAGI-phaseout limit)/(phaseout end- phaseout beginning)

2500 * (153000-140000)/(170000-140000)

=2500*13000/30000

How do you find the equation of a line given the slope and y-intercept?.

Answers

The equation of a line is typically written as y = MX + b where m is the slope and b is the y-intercepts.

First of all, remember what the equation of a line is:

y = MX + b

Where:

m is the slope, and b is the y-intercept

All you really have to do here is

replace m with 0, which is the slope you gave, and

replace b with 0, the y-intercept you gave,

in the equation y = MX + b.

If a point crosses the y-axis, then its miles are referred to as the y-intercept. The means of intercept of a line is the thing at which it intersects both the x-axis and y-axis.

in case you examine the graph, you may see that the factor in which Stealth is 0 and choice is 5 hits proper on the critical, vertical line - the y-axis. for the reason that this factor touches, or intercepts, the y-axis, its miles known as the y-intercept.

The x-intercept is in which a line crosses the x-axis, and the y-intercept is the thing in which the road crosses the y-axis.

y = MX + b is the slope-intercept shape of the equation of a straightaway line. inside the equation y = MX + b, m is the slope of the street, and b is the intercept. x and y represent the gap of the street from the x-axis and y-axis, respectively.

Pythagorean theorem describes the relationship between the sides of a right triangle. It states that the square of the hypotenuse is equal to the sum of the squares of the two other side.

c² = a² + b²

Let a = vertical distance between the two points

b = horizontal distance between the two points

c = distance between the two points / length of line segment

Hence, c² = (|y₂ - y₁|)² + (|x₂ - x₁|)².

Substitute the values of x and y and solve for c.

c² = (|y₂ - y₁|)² + (|x₂ - x₁|)²

c² = (|-1 - 10|)² + (|4 - -3|)²

The coefficients of the function, along with their meaning, are listed as follows:

m is the slope, representing the rate of change of y relative to x.b is the y-intercept of the function, which is the value of y when x = 0.

Given two points, only one line will pass through them.

Using a calculator, the lines are given as follows:

Points (1,3) and (2,7): y = 4x - 1.Points (2,7) and (6,2): y = -1.25x + 10.5.

Then the x-coordinate of the point in which the lines intersect is obtained as follows:

4x - 1 = -1.25x + 10.5

110° + ∠CBD = 180°

∠CBD = 70°

Therefore, The reflex angle CBD is measured at 70°, while the angle ABC is measured at 110°.

There are 8725 inect at a lab. If one thouand more were added,which digit in the number would change?

Answers

If 1000 more insects were added then the digit at the thousandth place will change, it will increase by 1.

The number of insects = 8725

1000 more insects added.

Therefore number of insects = 8725 + 1000 = 9725 insects

Hence only the number of insects changes the digit in the thousandths place only.

In the case of decimals, the place value system is equivalent to the whole number for the whole number portion. But there is another world of numbers that persists much past the decimal point, and in this world, we use decimal fractions to express the value.

As we proceed to the left, each place becomes ten times larger than the place value before it. As a result, to the right of each place, we get ones (1), tenths (1/10), hundredths (1/100), and so on.

There are two ways to read a decimal number. Read the whole number first, then the word "point," and finally the fractional part's digits separately.

martin is a food critic reviewing a restaurant that has 6 main courses, 3 desserts, and 5 appetizers he has yet to try. martin asks the server to surprise him with one of the remaining items. what is the probability that martin is served a main course?

Answers

3/7  is the probability that martin is served a main course.

What is the simple definition of probability?

A probability is a number that expresses the possibility or likelihood that a specific event will take place.

                            In addition to being expressed as percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.

A = Served with main course

n(A) = 6

S = sample space total no of different courses

n(S) = 6 + 3 + 5 = 14

P(A) = n(A)/n(S)  = 6/14 = 3/7

How will the input of F x 11 affect the graph of f/x x explain?.

Answers

The graph of f(x) = x will shift to the left 11 units because negative 11 is being subtracted from x which will be the required transformation.

Taking into account that f(x) = x becomes f(x) = x+11

This shows a horizontal displacement of x of 11 units to the left.

This is true since the original graph's origin is the x intercept. for a new purpose

x's intercept is -11.

The option it contains is the right one.

11 units to the left, I shifted.

x is taken away from by a negative -11.

Transform the coordinate plane's shapes by translating, rotating, or reflecting them. In the 19th century, Felix Klein introduced transformational geometry, a novel perspective on geometry. The majority of proofs in geometry are built upon object transformations. Any image in a coordinate plane can be altered using transformations.

Public Policy Alternative Positives Negatives In preparing for the upcoming holiday season, fresh toy company (ftc) designed a new doll called the dougie that teaches children how to dance. the fixed cost to produce the doll is $100,000. the variable cost, which includes material, labor, and shipping costs, is $31 per doll. during the holiday selling season, ftc will sell the dolls for $39 each. if ftc overproduces the dolls, the excess dolls will be sold in january through a distributor who has agreed to pay ftc $10 per doll. demand for new toys during the holiday selling season is extremely uncertain. forecasts are for expected sales of 60,000 dolls with a standard deviation of 15,000. the normal probability distribution is assumed to be a good description of the demand. ftc has tentatively decided to produce 60,000 units (the same as average demand), but it wants to conduct an analysis regarding this production quantity before finalizing the decision. (a) determine the equation for computing ftc's profit for given values of the relevant parameters (e.g., demand, production quantity, etc.). using this equation, compute ftc's profit (in dollars) when realized demand is equal to 60,000 (the average demand).
