The total that Tony has is 1465 while Gene has a total of 1565, hence they are not equivalent.

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

14 hundreds, six tens, and 5 ones = 14(100) + 6(10) + 5(1) = 1465

1 thousand, 4 hundreds, 16 tens. and 5 ones = 1(1000) + 4(100) + 16(10) + 5(1) = 1565

The total that Tony has is 1465 while Gene has a total of 1565, hence they are not equivalent.

According to the question the equation has been solved by using Pythagorean. The left-hand side of the identity simplifies to \(cos^2(x)\)

The Pythagorean Theorem can be used to find the correct angled triangle's missing length. The triangle contains three sides: the hypotenuse, this same opposite, which will always be the longest, and the adjacent side, which really doesn't touch the hypotenuse. The Pythagorean equation is: \(a^2+b^2=c^2.\)

We can start by using the reciprocal identity for cosecant:

\(cos(x) = 1/sin(x)\)

Then, we substitute this into the left-hand side of the identity:

\(sin(x)(csc(x) - sin(x)) = sin(x)(1/sin(x) - sin(x))\\= sin(x)/sin(x) - sin^2(x)\\= 1 - sin^2(x)\)

Using the Pythagorean identity for sine and cosine, we know that:

\(1 - sin^2(x) = cos^2(x)\)

Thus, the left-hand side of the identity simplifies to \(cos^2(x)\), which is equal to the right-hand side of the identity.

Therefore, the identity is verified.

The number of stamps Matthew has : 18 stamps.

In order to address this issue, a set of equations must be used.

Zane has 220 fewer than Jade and Matthew, so:

x + y  = z + 220

Jade has 140 less than Zane and Matthew, so:

y + z = x + 140

500 is what Jade and Zane have, thus

x + z = 500

z = 500 - x

Substituting the final equation for the first two:

x + y = z + 220

x + y = 500 - x + 220

2x + y = 720 ---eq1

And,

y + z = x + 140

y + 500 -x = x + 140

-2x + y = - 360   -----eq 2

Add the two equations together:

2x - 2y + y + y = 720 - 360

y = 360/ 2

y = 180

Thus, Matthew has 180 postage stamps.

The present value of a cash inflow of 1250 four years from now, given a required rate of return of 8%, is 918.79, rounded to 2 decimal places. Therefore, option (c) is the correct answer.

To find the present value of a future cash inflow, we need to discount the future value by a factor that takes into account the time value of money, or the opportunity cost of waiting for the money.

This factor is determined by the required rate of return, which is the minimum rate of return that an investor expects to earn on an investment with a similar level of risk.

In this case, we have a cash inflow of 1250 that will be received four years from now, and a required rate of return of 8%. To find the present value, we can use the formula for the present value of a single cash flow:

PV = FV / (1 + r)^n

where PV is the present value, FV is the future value, r is the required rate of return, and n is the number of years.

Plugging in the values, we get:

PV = 1250 / (1 + 0.08)^4

PV = 918.79

Therefore option (c) is the correct answer.

To compare the 3-month and 12-month moving average forecasts using the mean absolute deviation (MAD) criterion, we need to calculate the MAD for each model and then compare them. The MAD is a measure of the average magnitude of the forecast errors, and a lower MAD indicates a better forecast.

To calculate the MAD for the 3-month moving average model, we need to first calculate the forecasted values for each month by taking the average of the unemployment rates for the previous 3 months. For example, the forecasted value for April 2018 would be the average of the unemployment rates for January, February, and March 2018. We then calculate the absolute deviation between the forecasted value and the actual value for each month, and take the average of those deviations to get the MAD for the 3-month moving average model.

We can repeat this process for the 12-month moving average model, but instead of taking the average of the previous 3 months, we take the average of the previous 12 months.

Once we have calculated the MAD for both models, we can compare them to determine which model yields better results. Generally, a lower MAD indicates a better forecast. However, it is important to note that the MAD criterion only considers the magnitude of the forecast errors and does not take into account the direction of the errors (i.e., overestimation versus underestimation).

A sample is a subset of the population. When conducting a survey, it is often impractical to gather data from every member of a population, and therefore, a sample is used. The goal of a sample is to gather data that is representative of the population. In the case of the instructional designer, they would need to identify the population of learners they are interested in (e.g. learners enrolled in their course) and take a sample of those learners to estimate the proportion who use Firefox as their primary browser.

There are various sampling procedures that can be used, but the most common is simple random sampling. In simple random sampling, each member of the population has an equal chance of being selected for the sample. The instructional designer could use a random number generator or a table of random numbers to select their sample of learners. Once they have their sample, they can count the number of learners who use Firefox as their primary browser and use this proportion to estimate the proportion in the population.

Answer: The lowest possible product would be -6724 given the numbers 82 and -82.

We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.

Next we'll multiply the numbers together.

x(x+164)

x^2 + 164x

Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2

-b/2a = -164/2(1) = -164/2 = -82

So we know one of the values is -82. We can plug that into the equation to find the second.

The value of the correlation coefficient is 0.34. Thus, the option (B) 0.34 is the correct answer.

Given that a researcher measures the relationship between two variables, X and Y.

If SS(XY) = 340 and SS(X)SS(Y) = 320,000, then we need to calculate the value of the correlation coefficient.

Correlation coefficient:

The correlation coefficient is a statistical measure that determines the degree of association between two variables.

It is denoted by the symbol ‘r’.

The value of the correlation coefficient lies between -1 and +1, where -1 indicates a negative correlation, +1 indicates a positive correlation, and 0 indicates no correlation.

How to calculate correlation coefficient?

The formula to calculate the correlation coefficient is as follows:

r = SS(XY)/√[SS(X)SS(Y)]

Now, substitute the given values, we get:

r = 340/√[320000]r = 0.34

Therefore, the value of the correlation coefficient is 0.34. Thus, the option (B) 0.34 is the correct answer.

Answer:

If you set up a proportion 2/7     x/308 then you should get the answer of 88

Step-by-step explanation:

The future value of depositing $1,000 every year for 20 years, with payments made at the beginning of each period, at an interest rate of 7% compounded yearly, is approximately $43,865.18.

To calculate the future value of a series of deposits, we can use the formula for the future value of an ordinary annuity:

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

Where:

FV is the future value

P is the periodic payment

r is the interest rate per period

n is the number of periods

In this case, the periodic payment is $1,000, the interest rate is 7% (or 0.07), and the number of periods is 20.

Plugging these values into the formula, we get:

FV = 1000 * [(1 + 0.07)^20 - 1] / 0.07

  = 1000 * [1.07^20 - 1] / 0.07

  ≈ 1000 * [2.6532976 - 1] / 0.07

  ≈ 1000 * 1.6532976 / 0.07

  ≈ 43,865.18

Therefore, the future value of this series after 20 years would be approximately $43,865.18.

Answer:

The slope is \(\frac{5}{2}\) (5/2)

Step-by-step explanation:

Key skills needed: Subtraction, Division, Slope Formula

1) So to find the slope here, we use the slope formula.

Given 2 points \((x_1, y_1)\) and \((x_2, y_2)\)

To find the slope you do: \(\frac{y_2-y_1}{x_2-x_1}\)

2) So in this case, the 2 points are (-1,-2) and (1,3)

3) We can use the slope formula to find the slope

Now we do \(\frac{y_2-y_1}{x_2-x_1}\)

This would be: \(\frac{3-(-2)}{1-(-1)}\)

If you are subtracting -2, that means you add 2. If you are subtracting -1, then that means you add 1.

This means ---> \(\frac{3+2}{1+1}\)

3+2 is 5, and 1+1 is 2 so your slope would be \(\frac{5}{2}\) (5/2)

Step-by-step explanation:

The discriminant is used to determine the number and nature of the zeros of a quadratic. If the discriminant is positive and a perfect square, there are 2 rational zeros; if the discriminant is positive and not a perfect square, there are 2 rational complex zeros; if the discriminant is 0, there is 1 rational root; if the discriminant is negative, there are no real roots.

The roots/solutions/zeros of a quadratic are where the graph goes through the x axis. Those are the real zeros, even if they don't fall exactly on a number like 1 or 2 or 3; they can fall on 1.32, 4.35, etc. They are still real. If the graph doesn't go through the x-axis at all, the zeros are imaginary because the discriminant was negative and you can't take the square root of a negative number. As you can see on our graph, the parabola never goes through the x-axis. Therefore, the zeros are imaginary because the discriminant was negative.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

The coefficients of "x" and "y" are not multiples of each other. Therefore, there is no way to eliminate one variable and solve for the other. This indicates that the system has no solution.

The system of equations provided, 4x + 5y = 13 and -8x + 4y = 44, represents a set of linear equations with two variables, x and y. To determine if there is a solution, we can analyze the coefficients of x and y in each equation. By comparing the coefficients of y, we find that they are not proportional, meaning the lines represented by the equations are not parallel. However, when we compare the coefficients of x, we find that they are proportional with a ratio of -2. This implies that the lines are parallel and will never intersect. Therefore, the system has no common solution for x and y.

In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.

The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.

We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.

Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.

Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000

We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)

Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0

Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.
