The simplest form of a fraction is when the numerator (top number) and denominator (bottom number) have no common factors.

A fraction is a mathematical expression that represents a part of a whole, where a numerator is divided by a denominator. To simplify a fraction, we must divide both the numerator and the denominator by the same number until we cannot divide any further. To simplify a fraction, you must divide both the numerator and denominator by their greatest common factor (GCF).

For example, let's simplify the fraction 24/36. The GCF of 24 and 36 is 12. So, dividing both numbers by 12 will give us the simplified fraction 2/3.

24 ÷ 12 = 2

36 ÷ 12 = 3

Therefore, the simplified fraction of 24/36 is 2/3.

Mean, median and mode are the measures of central tendency that are used to describe a statistical sample. These measures are commonly used in statistical analysis and are important in understanding the general characteristics of a data set.

Here is a brief explanation of each of these measures Mean: The mean is the arithmetic average of a set of data. It is calculated by summing up all the values in a data set and dividing by the number of values in the set. The mean is sensitive to outliers, meaning that if there are any extreme values in the data set, the mean will be affected.Median: The median is the middle value in a set of data. It is the value that divides the data set into two equal parts. If there is an even number of values in a data set, the median is the average of the two middle values.

The median is less sensitive to outliers than the mean, meaning that extreme values will not have as much of an effect on the median. Mode: The mode is the most common value in a set of data. It is the value that appears most frequently in the data set. The mode is not sensitive to outliers, meaning that extreme values will not affect the mode. The mode can be used to describe the typical value of a data set. In summary, the mean tells you about the average value of a data set, the median tells you about the middle value of a data set, and the mode tells you about the most common value in a data set. These measures of central tendency are useful for understanding the general characteristics of a data set.

To calculate the monthly principal + interest payments for a house with a down payment and a mortgage using an Excel formula, you can use the PMT function. Here's how:

Calculate the loan amount by subtracting the down payment from the house cost. In this case, the down payment is 25% of $300,000, so it would be $75,000.
  Loan Amount = $300,000 - $75,000 = $225,000    

Determine the monthly interest rate by dividing the annual interest rate by 12. In this case, the annual interest rate is 2.75%, so the monthly interest rate would be 2.75% / 12 = 0.00229.

Determine the loan term in months. Since it's a 30-year mortgage, the loan term would be 30 * 12 = 360 months.

Use the PMT function in Excel to calculate the monthly principal + interest payment.
  Monthly Payment = -PMT(0.00229, 360, 225000)

The negative sign is used because the payment is an outgoing cash flow.

By using this formula in Excel, you can find the monthly principal + interest payments for your mortgage. Remember to adjust the interest rate, loan amount, and loan term if they differ from the example provided.

To calculate the monthly principal + interest payments using an Excel formula, you can use the PMT function by inputting the appropriate parameters: the monthly interest rate, loan term in months, and loan amount.

Answer:

D' (6, - 4 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin then multiply the coordinates of D by 2, that is

D(3, - 2 ) → D'(2 × 3, 2 × - 2 ) → D'(6, - 4 )

The minimum value of V occurs at x ≈ 0.93, which means that the volume of the box is smallest when the height is about 0.93 units.

To find the extreme values of V, we need to take the derivative of V and set it equal to zero. So, let's begin:

\(V(x) = x(10-2x)(16-2x)\)
Taking the derivative with respect to x:
\(V'(x) = 10x - 4x^2 - 32x + 12x^2 + 320 - 48x\)
Setting V'(x) = 0 and solving for x:
\(10x - 4x^2 - 32x + 12x^2 + 320 - 48x = 0\\8x^2 - 30x + 320 = 0\)
Solving for x using the quadratic formula:
\(x = (30 ± \sqrt{(30^2 - 4(8)(320))) / (2(8))\\x = (30 ± \sqrt{(1680)) / 16\\x = 0.93 or x =5.07\)
So, the extreme values of V occur at x ≈ 0.93 and x ≈ 5.07. To determine whether these are maximum or minimum values, we need to examine the second derivative of V. If the second derivative is positive, then the function has a minimum at that point. If the second derivative is negative, then the function has a maximum at that point. If the second derivative is zero, then we need to use a different method to determine whether it's a maximum or minimum.

Taking the second derivative of V:
V''(x) = 10 - 8x - 24x + 24x + 96
V''(x) = -8x + 106

Plugging in x = 0.93 and x = 5.07:
V''(0.93) ≈ 98.36 > 0, so V has a minimum at x ≈ 0.93.
V''(5.07) ≈ -56.56 < 0, so V has a maximum at x ≈ 5.07.

Now, to interpret these values in terms of the volume of the box, we need to remember that V(x) represents the volume of a box with length 2x, width 2x, and height x. So, the maximum value of V occurs at x ≈ 5.07, which means that the volume of the box is greatest when the height is about 5.07 units. The minimum value of V occurs at x ≈ 0.93, which means that the volume of the box is smallest when the height is about 0.93 units.

a) The extreme values of V are:

Minimum value: V(0) = 0

Relative maximum value: V(3) = 216

Absolute maximum value: V(4) = 128

b) The absolute maximum value of V at x = 4 represents the case where the box has a square base of side length 4 units, height 2 units, and width 8 units, which has a volume of 128 cubic units.

a) To find the extreme values of V, we first need to find the critical points of the function. This means we need to find where the derivative of the function equals zero or is undefined.

Taking the derivative of V(x), we get:

\(V'(x) = 48x - 36x^2 - 4x^3\)

Setting this equal to zero and solving for x, we get:

\(48x - 36x^2 - 4x^3 = 0\)
4x(4-x)(3-x) = 0

So the critical points are x = 0, x = 4, and x = 3.

We now need to test these critical points to see which ones correspond to maximum or minimum values of V.

We can use the second derivative test to do this. Taking the derivative of V'(x), we get:

\(V''(x) = 48 - 72x - 12x^2\)

Plugging in the critical points, we get:

V''(0) = 48 > 0 (so x = 0 corresponds to a minimum value of V)
V''(4) = -48 < 0 (so x = 4 corresponds to a maximum value of V)
V''(3) = 0 (so we need to do further testing to see what this critical point corresponds to)

To test the critical point x = 3, we can simply plug it into V(x) and compare it to the values at x = 0 and x = 4:

V(0) = 0
V(3) = 216
V(4) = 128

So x = 3 corresponds to a relative maximum value of V.
b) In terms of the volume of the box, the function V(x) represents the volume of a rectangular box with a square base of side length x and height (10-2x) and width (16-2x).
The minimum value of V at x = 0 represents the case where the box has no dimensions (i.e. it's a point), so the volume is zero.
The relative maximum value of V at x = 3 represents the case where the box is a cube with side length 3 units, which has a volume of 216 cubic units.

The equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is y = (5/2) * x^2y + 1. This equation represents a curve where the y-coordinate is a function of the x-coordinate, satisfying the conditions.

To determine an equation of the curve that satisfies the conditions, we can integrate the slope function with respect to x to obtain the equation of the curve. Let's proceed with the calculations:

We have:

Point: (0, 1)

Slope: 5xy

We can start by integrating the slope function to find the equation of the curve:

∫(dy/dx) dx = ∫(5xy) dx

Integrating both sides:

∫dy = ∫(5xy) dx

Integrating with respect to y on the left side gives us:

y = ∫(5xy) dx

To solve this integral, we treat y as a constant and integrate with respect to x:

y = 5∫(xy) dx

Using the power rule of integration, where the integral of x^n dx is (1/(n+1)) * x^(n+1), we integrate x with respect to x and get:

y = 5 * (1/2) * x^2y + C

Applying the initial condition (0, 1), we substitute x = 0 and y = 1 into the equation to find the value of the constant C:

1 = 5 * (1/2) * (0)^2 * 1 + C

1 = C

Therefore, the equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is:

y = 5 * (1/2) * x^2y + 1

Simplifying further, we have:

y = (5/2) * x^2y + 1

Answer:

y = -2/3x + 4

Step-by-step explanation:

In an equation that represents a line, the number with which no variable is multiplied is the y-intercept.

The number with which "x" is multiplied is the slope.

So in this case, the slope is -2/3; so the equation should be like -2/3x.

The y-intercept is 4, so it is the number with which no variable is multiplied.

So the equation is:

=> y = -2/3x + 4

Let x be the number of days Christen's book is overdue. Since the fine is the same as it would have been if she returned the book the previous day, then the fine is constant.

Let y be the fine for each day that the book is overdue. The fine for x days overdue is then yx. The fine for returning the book the previous day would be y(x - 1).

Since the fine is constant, we have: yx = y(x - 1)yx = xy - yyx - xy = -yy(x - 1) = -x We know that x is a nonnegative integer since it cannot be negative and must be an integer (you can't return a book "negative days" late!).

To determine if X and Y are independent or not from each other with the given information, we have to check if the given joint density function satisfies the following property:

f(x,y) = g(x) × h(y)

where g(x) and h(y) are the marginal density functions of X and Y respectively.

If the above equation holds, then X and Y are said to be independent of each other.If not, X and Y are dependent on each other.

Let's find the marginal density functions of X and Y.

The marginal density function of X:

fX(x) = ∫f(x,y)dy

∫0∞xe^-(x+y)dy = x

Step-by-step explanation:

The quadratic function f(x) = g(4x) has a turning point at (-3, 8)

If the quadratic function g(x) has a turning point at (-12,8), then it has the form

g(x) = a(x + 12)^2 + 8

where "a" is a constant that determines the shape of the quadratic curve.

To find the turning point of the function f(x) = g(4x), we substitute 4x for x in the equation for g(x)

f(x) = g(4x) = a(4x + 12)^2 + 8

Simplifying this expression, we have:

f(x) = 16a(x + 3)^2 + 8

This is also a quadratic function with a turning point at (-3, 8), which we can find by comparing it to the standard form of a quadratic function:

f(x) = a(x - h)^2 + k

where (h, k) is the turning point.

Therefore, the turning point at (-3, 8).

Step-by-step explanation:

If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n which means that he was able to but 2 sweaters and got $16 back. Therefore the formula would be 32n = 100 - 20

The formula for the number of sweaters will be 32n = 100 – 20.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Favian received a $100 gift card to a clothing store.

Using only the gift card, he was able to purchase n sweaters that cost $32 each and 1 belt for $20.

If there was no tax on the sweaters and belt,

Then the equation will be

32n + 1 x 20 = 100

    32n + 20 = 100

             32n = 80

                 n = 2.5 ≈ 2

If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n, which means that he was able to but 2 sweaters and got $16 back.

The question is asking about how much the government of Smartypants would need to subsidize college education per student to achieve the socially optimal level of education.

As per the graph given below, the socially optimal level of education is where MSB = MPC.

So, the government of Smartypants would need to subsidize college education per student by $2,000 to achieve the socially optimal level of education.

The subsidy shifts the supply curve to the right, and so the equilibrium quantity demanded of education increases from QP to QS.

As a result, the market price decreases from PP to PS.The diagram below shows the effects of a subsidy on the market for education. The supply curve shifts to the right, which increases the quantity of education from Q1 to Q2.

The demand curve does not shift as the cost to consumers has not changed, and the price of education falls from P1 to P2. The subsidy per student is represented by the distance between the original MPC and the new MSC curves at the socially optimal level of education.
