c) Based on your answers in the previous two questions, how much profit is this firm making at the profit maximizing level of output?
Answers
The profit-maximizing output of 1.91, the firm is incurring a loss of $29.42.
a) Find the profit-maximizing level of output (Q)To determine the profit-maximizing level of output, we must calculate the marginal cost and marginal revenue of the firm.MC= dTC/dQ= -6Q^2-100+68Q=2(17Q^2-34Q-50)So, the marginal cost of the firm is MC= 2(17Q^2-34Q-50)To find the marginal revenue (MR) we must differentiate the revenue function with respect to Q.MR= dTR/dQ= P + Q(dP/dQ)= 20-4QHence, the marginal revenue is MR= 20-4QAt the point of maximum profit, marginal cost (MC) equals marginal revenue (MR).Therefore, 2(17Q^2-34Q-50)=20-4Q34Q^2-68Q-100=0Solving the above equation gives Q=1.91Therefore, the profit-maximizing output is 1.91 units.b) What price should you charge for your product?The price the firm should charge for its product is given by the demand function, P=20-2Q.Substituting Q=1.91 into the demand function,P= 20-2(1.91) = $16.18c) Based on your answers in the previous two questions, how much profit is this firm making at the profit-maximizing level of output?The total profit of the firm is given by the difference between the revenue and the total cost.TR= P x Q = 16.18 x 1.91 = $30.92TC= 100-2(1.91)^3-100(1.91)+34(1.91)^2 = $60.34Profit = TR- TC= $30.92-$60.34= -$29.42At the profit-maximizing output of 1.91, the firm is incurring a loss of $29.42.

From the given information, we know that 14 boys chose German and 10 boys chose French. However, we don't have data on the number of girls choosing German or French.
Let's assume x girls chose German and y girls chose French.
Therefore, the completed two-way table would look like this:
French German Total
-----------------------------------
Boys 10 14 24
Girls y x x+y
Total 10+x 14+y 50
As for calculating the probability of picking a boy who chose German, we can use the formula:
P(Boy and German) = Number of boys who chose German / Total number of students
= 14 / 50
= 0.28 or 28%
Please note that without information about the number of girls choosing German or French, we cannot determine the specific values for boys and girls in each category.
what type of relationship is indicated in the scatterplot? a negative curvilinear relationship a positive linear or curvilinear relationship no relationship a negative linear relationship
Answers
The type of relationship indicated in the scatterplot is a negative curvilinear relationship.
A scatterplot is a type of graph that is used to display the relationship between two variables. In a scatterplot, the values of one variable are plotted on the x-axis and the values of the other variable are plotted on the y-axis. The relationship between the two variables can be determined by observing the pattern of the points in the scatterplot.
A negative curvilinear relationship is indicated when the points in the scatterplot form a curve that slopes downward. This means that as the values of one variable increase, the values of the other variable decrease, but not in a straight line. Instead, the relationship follows a curved pattern.
In contrast, a positive linear or curvilinear relationship is indicated when the points in the scatterplot form a curve that slopes upward, a negative linear relationship is indicated when the points in the scatterplot form a straight line that slopes downward, and no relationship is indicated when the points in the scatterplot do not form any discernible pattern.

The trigonometric function, Y = -4·cos 5·x - 10 is undefined at Y = 0, but the function arranged as Y = -4·cos(5·x - 10) has an x-intercept at x = π/10 + 2
What is a trigonometric function?A trigonometric function indicates the relationship between angles and the lengths of sides of angles.
The specified function can be presented as follows;
Y = -4·co(5·x) - 10
There are two unknown variables
The number of equations is one
The number of equations is less than the number of unknowns, the equation is said therefore, to be undetermined.The function, at Y = 0, can be evaluated as follows;
Y = 0 = -4·co(5·x) - 10
cos(5·x) = 10/(-4) = -2.5
5·x = arccos(-2.5) = Undefined
However, when the function is; Y = -4·cos((5·x) - 10), we get;
At Y = 0
0 = -4·cos((5·x) - 10)
cos((5·x) - 10) = 0/(-4) = 0
5·x - 10 = arccos(0) = π/2
Therefore;
x = (π/2 + 10)/5 = π/10 + 2
(-π/2 + 10)/5

Answers
That’s ur answer because you have to add 2x to the other side where 6y and then you divide the 2 from both sides and then 4 divided by 2=2 and then 6 divided by 2=3
Answer:
h = -3y + 2x
Step-by-step explanation:
Add 4x to both sides of the equation.
2h = −6y + 4x
Divide each term in 2h = −6y + 4x by 2 and simplify.
Divide each term in 2h = −6y + 4x by 2.
2h/2 = -6y/2 + 4x/2
Simplify the left side.
h = −6y/2 + 4x/2
Simplify the right side.
Simplify each term.
Cancel the common factor of −6 and 2.
h = -3y+2(2x)/2
Cancel the common factors.
Factor 2 out of 2.
h = -3y+2(2x)/2(1)
Cancel the common factor
h = -3y+2(2x)/2(1)
Rewrite the expression
h = -3y + 2x/1
Divide 2x by 1.
h = -3y + 2x

Answers
Answer:
Kenny is 18 years old Andrew is 10 years old Tim is 30 years old and Cameron is 5 years old
Step-by-step explanation:
Let a be Kenny's age , b be Andrew's age , c be Tim's age , d be Cameron's age
( b < a , b<c , d<b)
Kenny is 8 years older than Andrewn = > a = b + 8 (1)
Tim is 3 times as old as Andrew => c = 3 . b (2)
Cameron is 5 years younger than Andrew => d = b-5 (3)
The combined age of the four is 63 => a+b+c+d = 63 (4)
(1),(2),(3),(4) => b+8 + b + 3b + b-5 = 63 <=> 6b + 3 = 63 <=> b = 10
=> a= 10+8 =18, c = 3 . 10 = 30, d= 5

The average of the sample ranges for the weight of packages of Skittles is 0.11. So, the correct answer is (e) 0.11.
To find the average of the sample ranges for the weight of packages of Skittles, we first calculate the range for each sample. The range is the difference between the maximum and minimum values in each sample.
Sample 1: Range\(= 3.62 - 3.58 = 0.04\)
Sample 2: Range\(= 3.65 - 3.49 = 0.16\)
Sample 3: Range \(= 3.65 - 3.45 = 0.20\)
Sample 4: Range \(= 3.64 - 3.54 = 0.10\)
Sample 5: Range\(= 3.62 - 3.49 = 0.13\)
Next, we calculate the average of these sample ranges:
A\(verage = (0.04 + 0.16 + 0.20 + 0.10 + 0.13) / 5 = 0.11\)
Therefore, the average of the sample ranges for the weight of packages of Skittles is \(0.11\). So, the correct answer is (e) \(0.11.\)

Consider the following experiment. You are one of 100 people enlisted to take part in a study to determine the percent of nurses in America with an R.N. (registered nurse) degree. You ask nurses if they have an R.N. degree. The nurses answer "yes" or "no." You then calculate the percentage of nurses with an R.N. degree. You give that percentage to your supervisor.
a)What part of the experiment will yield discrete data?
- number of yes and no answers. -computed percentage - number of nurses at a hospital -percent of nurses in America with an R.N. degree -number of nurses in America
b)What part of the experiment will yield continuous data?
- number of yes and no answers. -computed percentage - number of nurses at a hospital -percent of nurses in America with an R.N. degree -number of nurses in America
Answers
a) The part of the experiment that will yield discrete data is the number of yes and no answers.
This is because the responses to the question "do you have an R.N. degree?" can only be either "yes" or "no," which are discrete categories. The number of yes responses and the number of no responses will be whole numbers and not continuous values.
b) The part of the experiment that will yield continuous data is the computed percentage of nurses with an R.N. degree. This is because the percentage can take on any value within the range of 0% to 100%, including decimal values. It is a continuous variable since it can have an infinite number of possible values within the given range.
The number of nurses at a hospital, percent of nurses in America with an R.N. degree, and the number of nurses in America are not directly obtained from the experiment but are instead population-level information.

the population of town c triples every 7 years. what is the annual percent change in the population of town c?
Answers
The annual percent change in the population of town C will be 16.9
From the formula for the annual increase in population, we have
A = P( 1 + r/100 )n
Where, A = new population
r = rate of increase in the population per annum
n = number of years
Since, from the question, we have
n = 7
A = 3P
Therefore,
3P = \(P( 1+ r/100 )^{7}\)
Or, 3 = \(P( 1+ r/100 )^{7}\)
31/7 = 1 + r/100
1.169 = 1 + r/100
0.169 = r/100

chase ran 36 3/4 miles over 6 days he ran the same distance each day how many miles did he run each day
Answers
Therefore, Chase ran 49/8 miles each day.
To find out how many miles Chase ran each day, we need to divide the total distance he ran (36 3/4 miles) by the number of days (6 days).
First, let's convert the mixed number into an improper fraction. 36 3/4 is equal to (4 * 36 + 3)/4 = 147/4.
Now, we can divide 147/4 by 6 to find the distance he ran each day:
(147/4) / 6 = 147/4 * 1/6 = (147 * 1) / (4 * 6) = 147/24.
Therefore, Chase ran 147/24 miles each day.
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 147 and 24 is 3.
So, dividing 147 and 24 by 3, we get:

Answers
The investment problem is modeled by an initial value problem (IVP) where the rate of change of the investment is determined by the initial investment, monthly deposits, and the interest rate.
a) The investment problem can be modeled by an initial value problem where the rate of change of the investment, y(t), is given by the initial investment, monthly deposits, and the interest rate. The IVP can be written as:
dy/dt = 0.09y + 200, y(0) = 500.
b) To solve the IVP, we can use an integrating factor to rewrite the equation in the form dy/dt + P(t)y = Q(t), where P(t) = 0.09 and Q(t) = 200. Solving this linear first-order differential equation, we obtain the solution for y(t).
c) To find the value of the investment after 2 years, we substitute t = 2 into the obtained solution for y(t) and calculate the corresponding value.
d) After 2 years, the monthly deposit increases to $300. To find the value of the investment a year later, we substitute t = 3 into the solution and calculate the value accordingly.
