Answer:

Step-by-step explanation:

(a) and (b) see diagram

(c) you can see from the graph, the purple line hits the parabola twice which is y=6   or k=6

(d)  Solving simultaneously can mean to set equal

6x - x² = k                        >subtract k from both sides

6x - x² - k = 0                  >put in standard form

- x² + 6x - k = 0               >divide both sides by a -1

x² - 6x + k = 0

(e) The new equation is the same as the original equation just flipped (see image)

(f)  The discriminant is the part of the quadratic equation that is under the root. (not sure if they wanted the discriminant of new equation or orginal.  I chose new)

discriminant formula = b² - 4ac

equation:   x² - 6x + 6 = 0            a = 1      b=-6    c = 6

discriminant = b² - 4ac

discriminant= (-6)² - 4(1)(6)

discriminant = 36-24

discriminant = 12

Because the discriminant is positive, if you put it back in to the quadratic equation, you will get 2 real solutions.

Using trend-adjusted exponential smoothing with alpha = 0.1 and beta = 0.2, the forecast for the architectural firm's August income is $94.92 thousand dollars. The mean squared error (MSE) for this forecast is 2.12 \((thousand dollars)^2\).

Trend-adjusted exponential smoothing combines exponential smoothing with a trend adjustment factor. The forecast for a given period is calculated based on the previous forecast and the previous trend value. In this case, the initial forecast for February is given as $85.0 thousand dollars, and the initial trend adjustment is 0.

To calculate the forecast for each month, we use the following formulas:

Level forecast = Previous level forecast + Previous trend adjustment

Trend forecast = Previous trend forecast + Beta * (Current level forecast - Previous level forecast)

Forecast for next period = Level forecast + Trend forecast

Using these formulas, we can calculate the forecasts for each month from February to July. Then, for August, we can apply the trend adjustment formula using the previous level forecast and trend forecast. The resulting forecast for August is $94.92 thousand dollars.

The mean squared error (MSE) is a measure of the accuracy of the forecast. It is calculated by taking the average of the squared differences between the actual income values and the forecasted values. In this case, the MSE for the forecast developed using trend-adjusted exponential smoothing is 2.12 \((thousand dollars)^2\). A lower MSE indicates a better fit between the forecast and the actual data.

Step-by-step explanation:

A way to find the equation of the graph is to find the solutions.

On the graph, the solutions are where the function intersects the x-axis. That would be where x = -2, x = 1, and x = 3.

In the equations, you will need to find factors when the x is inputted, the factor equals 0. For example, one of the factors is (x + 2). This is because x + 2 = 0, so x = 0 - 2, so x = -2. So, the three factors are (x + 2), (x - 1), and (x - 3).

The inequality that describes how many movies Parv can buy is: n ≤ 10.025

Let's denote the number of movies Parv wants to buy as n. We are given that each movie costs $3.99. To determine the inequality that describes how many movies Parv can buy, we need to consider the amount of money he has remaining after purchasing the pack of games.

Parv starts with a $50 gift card and spends $9.99 on a pack of games. The remaining amount on the gift card is $50 - $9.99 = $40.01.

Now, let's consider the cost of n movies. Each movie costs $3.99, so the total cost of n movies would be n * $3.99.

Since Parv wants to buy the movies using the remaining amount on his gift card, we can set up the inequality:

n * $3.99 ≤ $40.01

This inequality states that the total cost of n movies, represented by n * $3.99, must be less than or equal to the remaining amount on the gift card, which is $40.01.

Simplifying the inequality further, we have:

3.99n ≤ 40.01

Now, if we want to solve for n, we can divide both sides of the inequality by 3.99:

n ≤ 40.01 / 3.99

Calculating this value, we have:

n ≤ 10.02506265664

Therefore, the inequality that describes how many movies Parv can buy is:

n ≤ 10.025

This means that Parv can buy a maximum of 10 movies, as he cannot purchase a fractional part of a movie.

The random number 0.23, when interpreted in the given frequency distribution of demand, would correspond to a demand of 1.

In order to interpret the random number 0.23, we need to refer to the frequency distribution of demand. A frequency distribution provides information about the different values of a variable and their corresponding frequencies or probabilities. However, since the frequency distribution of demand is not provided, we cannot determine the exact values and frequencies for each demand level.

Nevertheless, assuming that the demand levels in the frequency distribution are discrete and start from 0, it is likely that the random number 0.23 falls within the range of the cumulative probabilities for a demand level of 1. The cumulative probability represents the probability of observing a value less than or equal to a particular demand level.

To interpret the random number, we can compare it to the cumulative probabilities associated with each demand level. If the random number falls within the cumulative probability range of a specific demand level, then that demand level would be the interpretation. Since the random number 0.23 falls within the range for a demand of 1, we can conclude that the demand corresponding to the random number 0.23 is 1.

Based on the given parameters, the amount of the investment after 4 years is $1030

The given parameters about the compound interest are

Principal Amount, P = $1000

Interest Rate, R = 0.85%

Time, t = 4

Number of times, n = 1 i.e. annually

Compound interests are different from simple interest, and they are calculated using the following compound interest formula

CI = P(1 + R/n)^nt - P

To calculate the amount, we have:

A = P + CI

So, the equation becomes

A = P + P(1 + R/n)^nt - P

Evaluate the like terms

A = P(1 + R/n)^nt

Substitute the known values in the above equation

A = 1000 * (1 + 0.85%/1)^(1 * 4)

Express 0.85% as decimal

A = 1000 * (1 + 0.0085/1)^(1 * 4)

Evaluate the sum

A = 1000 * (1.0085/1)^(1 * 4)

Morning Smiles earned a 5% commission and $45,000 in additional selling costs by selling 8,000 coffee makers for $100 each. Admin costs came to $47,50 total cost: $612,500.

For a total of $612,500, the Morning Smiles Coffee Company sold 8,000 stoneware french press coffee machines in March. Each coffee maker cost $100 to purchase. Two other types of selling costs were incurred by the business: commissions equivalent to 5% of the sale price and additional selling costs totaling $45,000. The overall cost of administration was $47,500. By multiplying the $100 sales price by the 8,000 coffee makers that were sold, or $800,000, the entire cost of sales was determined. The commission of $40,000 and the overall selling charges of $45,000 (5% of $800,000) were then subtracted from the total cost of sales to yield a final cost of $612,500.

Step-by-step explanation:

We are given two complex numbers:

\(\displaystyle m + ni \text{ and } p + qi\)

Where m, n, p, and q are real numbers.

And we want to determine the relationship among m, n, p, and q such that the product of the two complex numbers will only have an imaginary part.

Find the product:

\(\displaystyle \begin{aligned} (m+ni)(p+qi) &= p(m+ni) + qi(m+ni) \\ &= (pm + pni) + (qmi + qni^2) \\ &= (pm + pni) + (qmi - qn) \\ &= (pm - qn) + i(pn + qm) \end{aligned}\)

Therefore, for the product to have only an imaginary part, the real part must be zero and the imaginary part must not be zero. That is:

\(\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0\)

To determine the rejection region for the hypothesis H0: μd = 0 with Ha: μd > 0 and α = 0.1, you will consider the t-value given, which is t > 1.677926720776.

In this case, the rejection region is the set of all values of the test statistic t that lead to the rejection of the null hypothesis. As the alternative hypothesis suggests that μd is greater than 0, the rejection region will be in the right tail of the t-distribution.

Given α = 0.1, this indicates a 10% significance level. Therefore, the rejection region is defined by all t-values greater than 1.677926720776. If the calculated test statistic from your data is within this region (i.e., t > 1.677926720776), then you would reject the null hypothesis H0: μd = 0 in favor of the alternative hypothesis Ha: μd > 0.
