At a price of $5 supply and demmand are the same.

So we need to find how many slices of cake canbe sold at $2

Trace the supply demmand curve ,that is represented by

Q supplied + Q demanded = $ 5

At a price of $2 ,then shortage in price would be 8-2 =]$6

and with $6 can be buyed 6/2 =3 slices.

So then final answer is a shortage of 3 slices.

The overall percentage decrease from their summer to winter prices is 50.38%.

Percentage decrease means difference between starting and ending values. It shows a loss of value from the original expressed as a percentage regardless of units. The amount of decrease is the original amount minus the final amount.

Percentage decrease formula can be derived by dividing the decreased value by the original value and multiplying that with 100. Here, Decreased Value = (Original Value – New Value / Original Value)

Data

Original value = $6.55

New value = $3.25

The percentage decrease of the price is computed as:

= ($6.55 - $3.25) / $6.55

= $3.3 / $6.55 * 100

= 50.3816794

= 50.38%

A ∩ B is the intersection of sets A and B, which is the set of elements that are in both A and B.

A = {2, 3, 5, 7} and B = {1, 2, 5, 10}, so A ∩ B = {2, 5}.

B ∩ D^c is the intersection of set B and the complement of set D, which is the set of elements in B that are not in D.

B = {1, 2, 5, 10} and D^c = {1, 4, 6, 8, 9, 10}, so B ∩ D^c = {1, 10}.

A^c is the complement of set A, which is the set of elements in U that are not in A.

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and A = {2, 3, 5, 7}, so A^c = {1, 4, 6, 8, 9, 10}.

C ∩ D is the intersection of sets C and D, which is the set of elements that are in both C and D.

C = {1, 2, 3, 6} and D = {3, 5, 7}, so C ∩ D = {3}.

B u D^c is the union of set B and the complement of set D, which is the set of elements that are in B or in the complement of D, or both.

B = {1, 2, 5, 10} and D^c = {1, 4, 6, 8, 9, 10}, so B u D^c = {1, 2, 4, 5, 6, 8, 9, 10}.

The probability of rolling a specific number is 1/6 or approximately 0.1667.

When rolling a fair number cube with faces numbered 1 through 6, each face has an equal chance of landing face-up. This means the probability of rolling any specific number is 1 out of the total number of faces, which is 6. Therefore, the probability of rolling a specific number is 1/6 or approximately 0.1667.

The dot on the number line represents the probability of an event occurring when rolling the number cube. To determine what this event could be, consider the possible outcomes when rolling the cube and compare their probabilities to the dot's position on the number line.

For example, if the dot is located at 1/6 on the number line, this could represent the probability of rolling a single specific number, such as rolling a 3. If the dot is located at 1/2 or 0.5, it could represent the probability of rolling an even number (2, 4, or 6) since there are three even numbers out of the six total faces, making the probability 3/6 or 1/2.

In summary, the dot on the number line represents the probability of an event occurring when rolling a fair number cube. To identify the event, compare the dot's position on the number line with the probabilities of different outcomes resulting from rolling the cube.

Step-by-step explanation:

\(c+13 > 78\)

They must collect over 78 coats. They already have 13 so they must either add that to the amount they still need to collect or subtract it from the number they're trying to beat.

To solve the system of equations using the elimination method, we want to eliminate one of the variables by adding or subtracting the two equations. We can then use the resulting equation to solve for the remaining variable, and then substitute that value back into one of the original equations to solve for the other variable.

In this case, we notice that if we multiply the second equation by 2, we can eliminate the variable x by subtracting the two equations:

30x + 50y = 420     (equation 1)

15x + 35y = 220     (equation 2)

-----------------

 30x + 70y = 440   (2 x equation 2)

- 30x - 50y = -420  (equation 1)

-----------------

      20y = 20

Now we have an equation involving only y. Solving for y, we get:

20y = 20

y = 1

Substituting this value back into one of the original equations, we can solve for x:

15x + 35y = 220   (equation 2)

15x + 35(1) = 220

15x + 35 = 220

15x = 185

x = 185/15

x = 37/3

Therefore, the solution to the system of equations is x = 37/3 and y = 1.

Answer:

y = 1, x = 37/3

Step-by-step explanation:

30x + 50y = 420

-2(15x + 35y = 220)

x cancel each other (30x - 30x)

50y - 70y = -20y

220 * -2 = -440

420 - 440 = -20

-20 / -20 = 1

y = 1

420 - 50 = 370

370 / 30 = 37/3

x = 37/3

The expected total dollar net operating Income for next year = $70,000

1) The contribution format income statement for the game last year, and the degree of operating leverage is computed below:

Contribution format income statement for the game last year Sales (15,000 × $20) = $300,000

Variable expenses (15,000 × $6) = $90,000

Contribution margin = $210,000

Fixed expenses = $182,000Net operating income = $28,000

Degree of operating leverage = Contribution margin / Net operating income= $210,000 / $28,000= 7.5 2)

The expected percentage increase in net operating income for next year:

The expected sales in next year = 18,000

games selling price per game = $20

Therefore, Total sales revenue = 18,000 × $20 = $360,000

Variable expenses = 18,000 × $6 = $108,000

Fixed expenses = $182,000

Expected net operating income = Total sales revenue – Variable expenses – Fixed expenses

= $360,000 – $108,000 – $182,000= $70,000

The expected percentage increase in net operating income = (Expected net operating income - Last year's net operating income) / Last year's net operating income*100= ($70,000 - $28,000) / $28,000*100= 150%

The expected total dollar net operating income for next year = $70,000

Answer:

a. Angel has a greater flat fee

b. Difference = $130

Step-by-step explanation:

Given

Rose:

\(Flat\ Fee = \$50\)

\(Rate = \$12\)

Angel

Guests --- Charges

10 -------- $180

15 -------- $255

25 -------- $405

30 -------- $480

Solving (a): Who charges the greater flat fee?

We have that the flat fee of Rose is:

\(Flat\ Fee = \$50\)

For Angel, we need to determine the equation of the given table

Start by calculating the slope (m) of the table

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Where x and y represent any two corresponding values of the guests and the charges.

\((x_1,y_1) = (10, 180)\)

\((x_2,y_2) = (30, 480)\)

So: \(m = \frac{y_2 - y_1}{x_2 - x_1}\) becomes

\(m = \frac{480 - 180}{30 - 10}\)

\(m = \frac{300}{20}\)

\(m = 15\)

Next, we calculate the equation using:

\(y - y_1 = m(x - x_1)\)

Where

\(m = 15\)

\((x_1,y_1) = (10, 180)\)

\(y - 180 = 15(x - 10)\)

\(y - 180 = 15x - 150\)

Add 180 to both sides

\(y - 180 + 180 = 15x - 150 + 180\)

\(y= 15x + 30\)

From the equation above:

The slope = 15 --- This represents the hourly rate

and

y intercept = 30 --- This represents the flat fee

This is better represented as:

Angel

\(Flat\ Fee = \$30\)

\(Rate = \$15\)

and

Rose:

\(Flat\ Fee = \$50\)

\(Rate = \$12\)

By comparison, Angel has a greater flat fee

Solving (b): Difference between total charges of 50 guests for both caterers.

For angel, the equation is:

\(y= 15x + 30\)

and x = 50.

So:

\(y = 15 * 50 + 30\)

\(y = 750 + 30\)

\(y = 780\)

For Rose,

First, we need to determine the equation.

\(Flat\ Fee = \$50\)

\(Rate = \$12\)

The equation is:

\(y = Flat\ Fee + Rate * x\)

\(y = 50 + 12 * x\)

So, the total charges for 50 guests is:

\(y = 50 + 12 * 50\)

\(y = 50 + 600\)

\(y = 650\)

The difference is then calculates as:

\(Difference = 780 - 650\)

\(Difference = \$130\)

The number which is lesser than its square is 12/11

When a number is multiplied by itself, the result is a square number. For instance, 25 is a square number as it is composed of 5 lots of 5, or 5 × 5. 

The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. It follows that a a = b if "a" is the square root of "b." Every integer has two square roots, one of a positive value and one of a negative value, because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2. However, the square root of a number is typically only expressed as the positive value.

The appropriate confidence interval for estimating the population mean with a 98% level of confidence when the sample size is 18 and the sample mean is 4.27 with a sample standard deviation of 0.78 can be calculated using the t-distribution as:

t = ta/2, n-1 = t0.01/2, 17 ≈ 2.898

Margin of error = t[s/√n)] ≈ 2.898 [(0.78/√18)] ≈ 0.538

where tα/2, n-1 is the critical value from the t-distribution with n-1 degrees of freedom at a significance level of α/2.

Thus, the 98% confidence interval can be calculated as:

4.27 ± 0.538

= [3.732, 4.808]

Therefore, the closest option to the appropriate 98% confidence interval is (C) 4.27 ± 2.552 (0.78/√18), which is equivalent to [3.718, 4.822].
