This statement is False.

The formula provided in the statement is used to calculate the variance of the sample mean difference between two independent samples, but it is not necessarily true that the sample variances, and , are independent of one another.

The sample variances are calculated based on the data from their respective samples, and thus their relationship will depend on the specific data and the underlying population distributions.

For example, let's consider two samples of size n = 25, one from a normal population with mean 100 and variance 10, and another one from a normal population with mean 110 and variance 20. The sample variances for each sample are:

S1² = 9.6 and S2² = 20.8

Answer:

The highest common factor (HCF) of 24 and 20 is 4.

Step-by-step explanation:

Answer:

64 dimes and 34 quarters.

Step-by-step explanation:

Let d represent the amount of dimes and q represent the amount of quarter Julie has.

She has in total 98 coins. Therefore:

\(d+q=98\)

Each dime is worth 0.10 and each quarter is worth 0.25. Together, they are worth in total $14.90. Therefore:

\(0.1d+0.25q=14.90\)

We have a system of equations. We can solve this using substitution.

First, we can multiply the second equation by 100 to simplify. So:

\(10d+25q=1490\)

From the first equation, we can subtract q from both sides:

\(d=98-q\)

Substitute this into the second equation:

\(10(98-q)+25q=1490\)

Distribute:

\(980-10q+25q=1490\)

Combine like term:

\(15q+980=1490\)

Subtract:

\(15q=510\)

Therefore:

\(q=34\)

So, Julie has 34 quarters.

Returning to our first equation:

\(d+q=98\)

Substitute:

\(d+34=98\)

Therefore:

\(d=64\)

Thus, Julie has 64 dimes and 34 quarters.

The square with fraction of 1/8 part of it colored is represented by the figure D.

Given that,

There is a square with line segments drawn inside it.

The line segments are drawn either from the vertices or the midpoints of other line segments.

Fraction of 1/8 part of the square is colored means that 1 parts out of 8 equal parts that the square is divided is colored.

In the figure D, the square is divided in to 8 equal parts by first joining the midpoints of the opposite sides getting 4 squares and then joining the diagonals of the smaller squares.

So there are 8 parts and 1 part is colored.

por que al sumar 45 + 15 porciento da 51.75

When a graph or a point on the Cartesian plane is symmetric about the origin or with respect to the origin, it means that the graph or point maintains its shape and position when reflected across the origin.

In other words, if you draw a line passing through the origin and the graph or point, the portion of the graph or point on one side of the line will be an exact mirror image of the portion on the other side.

To determine if a graph is symmetric about the origin, we can check if the coordinates of a point on the graph, (x, y), satisfy the condition that (-x, -y) is also on the graph. For example, if the point (2, 3) is on the graph, we can verify that (-2, -3) is also on the graph.

Similarly, for a single point on the Cartesian plane to be symmetric about the origin, its coordinates (x, y) must satisfy the condition that (-x, -y) is also a point on the plane. For instance, if the point (4, -1) is symmetric about the origin, (-4, 1) should also be a point on the plane.

symmetry about the origin in the Cartesian plane refers to maintaining the same shape and position when reflected across the origin. It involves verifying that for every point (x, y) on the graph or plane, (-x, -y) is also a point on the graph or plane.

Answer:

12 hours

Step-by-step explanation:

Let x hours be the time it will take you to mow the greens at the golf course.

Since Kim can mow twice as fast, it will take Kim x / 2 hours to mow the greens.

In 1 hour, you will mow 1 / x of the greens

in 1 hour, Kim will mow 1 / (x / 2) of the greens= 2 / x of the greens

In 4 hours, you will mow 4 * 1 / x of the course = 4 / x of the greens

In 4 hours, Kim will mow 4 * 1 / (x / 2) of the course = 4 / (x / 2) = 8 / x of the greens.

Since we are dealing in fraction, the sum of the amount of greens that they would individually mow in 4 hours should be 1. i.e

(4 / x) + (8 / x) = 1

12 / x = 1

Solve for x;

x = 12

Therefore, it will take you 12 hours to mow the greens alone.

Answer:

1. The cost of equity can be derived from the share price, which is the present value of the expected dividend one year from now(using the present value of growing perpetuity) as shown below:

share price=D1/(r-g)

share price=$500

D1=expected dividend one year from now=$4

r=cost of equity=unknown

g=constant growth rate=9%

$500=$4/(r-9%)

$500*(r-9%)=$4

r-9%=$4/$500

r=($4/$500)+9%

r=9.8

the Cost of Equity for the project is 9.8%

2. Compute the relevant cost of debt for this project is 5.53%

Market Value= 1,150

Face Value= 1,000

Term= 5 years, 10 semi-annual periods

Coupon Rate= 9%, 4.5% semi-annual rate

Tax Rate= 30%

N=10(semiannual coupons in 5 years)

PMT=45(semiannual coupon=face value*coupon rate/2=$1000*9%/2=$45)

PV=-1150(current market price)

FV=1000(face value of the bond is $1,000)

CPT(press compute)

I/Y=2.762766%(semiannual yield)

annual yield=2.762766%*2

annual yield=5.53%

3. The weighted average cost of capital is the sum of equity and the after-tax cost of debt multiplied by their respective market value weights

WACC=(cost of equity*weight of equity)+(after-tax cost of debt*weight of debt)

cost of equity=9.80%

the market value of equity raised=shares issued*market price of the share

the market value of equity raised=80,000*$500

the market value of equity raised=$40 million

weight of equity=market value of equity/total amount raised

weight of equity=$40 million/$100 million

weight of equity=40.00%

weight of debt=1-weight of equity

weight of debt=1-40.00%

weight of debt=60.00%

after-tax cost of debt=bond yield*(1-tax rate)

the after-tax cost of debt=5.53%*(1-30% )

the after-tax cost of debt=3.87%

WACC=(9.80%*40.00%)+(3.87%*60.00%)

WACC= 6.2426% or 6.24%

Therefore the WACC is 6.2426% or 6.24% rounded off to 2decimal place

Step-by-step explanation:

5. Depreciation schedule:

Year 1 = 80 × 25% = 20

Year 2 = (80-20) × 25% = 15

Year 3 = (80-20-15) × 25% = 11.25

Year 4 = (80-20-15-11.25) × 25% = 8.4375

Year 5 = (80-20-15-11.25-8.4375) × 25% = 6.328125

EBT = revenue - Expenses - depreciation

Year 1 = 120 - 80 - 20 = 20 Million

Year 2 = 120-80- 15 = 25 Million

Year 3 = 120-80- 11.25 = 28.75 Million

Year 4 = 120-80- 8.4375 = 31.5625 Million

Year 5 = 120-80- 6.328125 = 33.671875Million

The cost of equity of the project through the use of Gordan's formula will be 9.87%.

It should be noted that the price of stock is computed thus:

= Previous dividend + Growth / Cost of equity - Growth

Po = Do + g/Ke - g

500 = 4 + 9%/Ke - 9%

500 = 4 + (0.09 × 4) / Ke - 9%

500 = 4.36/Ke - 9%

500(Ke - 9%) = 4.36

500Ke = 4.36 + 45

500Ke = 49.36

Ke = 49.36/500

Ke = 9.87%

The cost of debt will be:

= Interest rate (1 - Tax rate)

= 9% × (1 - 30%)

= 9% × 0.7

= 6.30%

The amount of the cost of debt will be:

= $1000 × 6.30%

= $63.00

The test-statistic (z-score) is 1.19984.

To find the test statistic (z-score) using the p-value, you will need to use the inverse of the standard normal cumulative distribution function (CDF), also known as the inverse normal function or the "normal inverse function." This function can be found using a calculator or a spreadsheet program with built-in functions, or you can use a table of standard normal probabilities to find the corresponding z-score for a given p-value.

For example, if the p-value is 0.05, you would look up the corresponding z-score in a table of standard normal probabilities and find that it is approximately 1.645. This means that the test statistic (z-score) for a p-value of 0.05 is 1.645.

It's important to note that this method only works for a one-tailed test, for a two-tailed test you need to divide your p-value by 2 and then use the inverse normal function.

so, the p-value is 0.1151, you would look up the corresponding z-score in a table of standard normal probabilities and find that it is approximately 1.19984.

Therefore, the test-statistic (z-score) is 1.19984.

Since x and y are independent, we have:

fxy(x,y) = fx(x) * fy(y)

where fx(x) and fy(y) are the probability density functions of x and y, respectively.

The probability density function of a uniform(0,1) random variable is:

f(x) = 1, 0 < x < 1

Therefore, the probability density functions of x and y are:

fx(x) = 1, 0 < x < 1

fy(y) = 1, 0 < y < 1

Using the formula for fxy(x,y), we have:

fxy(x,y) = fx(x) * fy(y) = 1 * 1 = 1, 0 < x < 1, 0 < y < 1

To determine the area of the base, height, and volume of a rectangular prism, we need more specific information such as the measurements of its dimensions (length, width, and height).

Without these values, we cannot provide an exact answer. However, I can explain the formulas and concepts involved. The base of a rectangular prism refers to one of its faces, which is a rectangle. To calculate the area of the base, we need to know the length and width of the rectangle. The formula for the area of a rectangle is A = length * width. The result will be in square units, such as square centimeters.

The height of a rectangular prism refers to its vertical dimension. To find the height, we need the measurement from the base to the top face. This measurement is typically perpendicular to the base. The height is usually given in units such as centimeters. The volume of a rectangular prism can be calculated by multiplying the area of the base by the height. The formula for the volume of a rectangular prism is V = base area * height. The result will be in cubic units, such as cubic centimeters.

To obtain the specific values for the area of the base, height, and volume of a rectangular prism, you will need to provide the measurements of its dimensions (length, width, and height).

The constants are a = 1 and b = 4. The zeros of p(x) are 2+i, 2-i, and their complex conjugates.

Since 2+i is a zero of p(x), its conjugate, 2-i, must also be a zero. Complex zeros always come in conjugate pairs when the coefficients of the polynomial are real.

Let's use this information to find the values of a and b.

If 2+i is a zero of p(x), then (x - (2+i)) must be a factor of p(x). Similarly, (x - (2-i)) must also be a factor.

Using the factor theorem, we can express p(x) in factored form as follows:

p(x) = (x - (2+i))(x - (2-i))(x - k)

Multiplying the first two factors using the difference of squares, we get:

p(x) = ((x - 2) - i)((x - 2) + i)(x - k)

= [(x - 2)² - (i)²](x - k)

= [(x - 2)² + 1](x - k)

Expanding the squared term, we have:

p(x) = (x² - 4x + 4 + 1)(x - k)

= (x² - 4x + 5)(x - k)

Now, comparing this expression with the given expression for p(x) = x³ + ax² + bx - 15, we can equate the coefficients of the corresponding powers of x.

For the x³ term, we have:

1 = 0 (coefficient of x³)

For the x² term, we have:

a = 1 (coefficient of x²)

For the x term, we have:

b - 4 = 0 (coefficient of x)

For the constant term, we have:

-15 = 5k (constant term)

From these equations, we can solve for a, b, and k:

From a = 1, we have a = 1.

From b - 4 = 0, we have b = 4.

From -15 = 5k, we have k = -3.

Therefore, the values of a, b, and k are a = 1, b = 4, and k = -3.

Now, let's find the remaining zero(s) of p(x).

We know that (x - k) is a factor of p(x), so we substitute k = -3:

p(x) = (x² - 4x + 5)(x + 3)

Now, to find the zeros of p(x), we set p(x) equal to zero and solve for x:

(x² - 4x + 5)(x + 3) = 0

Either (x² - 4x + 5) = 0 or (x + 3) = 0

For the first equation, we can use the quadratic formula to find its zeros:

x = [4 ± √(4² - 4(1)(5))] / (2(1))

= [4 ± √(16 - 20)] / 2

= [4 ± √(-4)] / 2

Since the discriminant is negative, the quadratic equation does not have real solutions. Hence, there are no additional real zeros.

However, we have already determined that the complex zeros are 2+i and 2-i.

Therefore, the zeros of p(x) are:

2+i, 2-i, and the complex conjugates of these roots.

To summarize:

a = 1

b = 4
