The inverse demand function of the given demand function is p = 50 - q/2.
A graph that depicts the relationship between a product's price and demand is called a demand curve. On a demand graph, the horizontal axis represents the amount desired, while the vertical axis represents the product's price.
The price is a function of the quantity required when there is an inverse demand curve. The inverse of a demand curve indicates that variations in the amount required cause changes in price levels. The formula for calculating the demand curve for a product yields the graph of an inverse demand curve.
Given demand function: q = 100 - 2p.
To find the inverse demand function, we find the inverse of the equation, by isolating p, to get:
q = 100 - 2p,
or, 2p = 100 - q,
or, p = 100/2 - q/2,
or, p = 50 - q/2.
Thus, the inverse demand function of the given demand function is p = 50 - q/2.

We are given a triangle that is split into two right angled triangles
The source triangle has been identified to be an equilateral triangle with all sides and angles equal.
Since all the internal angles in an equilateral triangle equals 180 degrees, we then know that:
60 + 60 + x + x = 180 degrees
Adding up like terms give:
120 + 2x = 180
Subtracting 120 from both sides gives:
2x = 180 - 120
2x = 60
Dividing both sides by 2 gives:
x = 30 degrees

After being rejected for employment, Kim Kelly learns that the Bellevue Credit Company has hired only five women among the last 18 new employees. She also learns that the pool of applicants is very large, with an approximately equal number of qualified men as qualified women. Help her address the charge of gender discrimination by finding the probability of getting five or fewer women when 18 people are hired, assuming that there is no discrimination based on gender.
Does the resulting probability really support such a charge?
Answers
Answer:
0.0481 = 4.81% probability of getting five or fewer women when 18 people are hired. Since this probability is lower than 5%, it means that five or fewer woman being hired is an unlikely event, and supports the charge.
Step-by-step explanation:
For each new employee hired, there are only two possible outcomes. Either it is a woman, or it is not. The probability of an employee being a woman is independent of any other employee. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
And p is the probability of X happening.
She also learns that the pool of applicants is very large, with an approximately equal number of qualified men as qualified women.
This means that \(p = 0.5\)
Help her address the charge of gender discrimination by finding the probability of getting five or fewer women when 18 people are hired, assuming that there is no discrimination based on gender.
This is \(P(X \leq 5)\) when \(n = 18\)
So
\(P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)\)
In which
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 0) = C_{18,0}.(0.5)^{0}.(0.5)^{18} \approx 0\)
\(P(X = 1) = C_{18,1}.(0.5)^{1}.(0.5)^{17} = 0.0001\)
\(P(X = 2) = C_{18,2}.(0.5)^{2}.(0.5)^{16} = 0.005\)
\(P(X = 3) = C_{18,3}.(0.5)^{3}.(0.5)^{15} = 0.0031\)
\(P(X = 4) = C_{18,4}.(0.5)^{4}.(0.5)^{14} = 0.0117\)
\(P(X = 5) = C_{18,5}.(0.5)^{5}.(0.5)^{13} = 0.0327\)
\(P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0 + 0.0001 + 0.0005 + 0.0031 + 0.0117 + 0.0327 = 0.0481\)
0.0481 = 4.81% probability of getting five or fewer women when 18 people are hired. Since this probability is lower than 5%, it means that five or fewer woman being hired is an unlikely event, and supports the charge.

For the question of total area of the cuboid is 200cm^.
I understand where we divide 150 by 4.
But why do I need to multiply by 5, when there are 6 faces.
Answers
You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.
When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.
A cuboid has six faces, but each face has a pair that is identical in size and shape.
Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.
To find the surface area of a cuboid, you can add up the areas of all its faces.
However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:
(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.
By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.
Essentially, you are considering one face from each pair and then summing their areas.
Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.
When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.
Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.
Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.

20% = 4
100% = 20
The total number of people in the group is 100 people.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2

20% = 4
Now,
The percentage of the total number of people in the group = 100%
So,
20% = 4
Multiplying 5 on both sides.
5 x 20% = 5 x 4
100% = 20

You are planning a 7-day trip to Gdańsk. The probability that it will rain on any of these days is 0.4. What is the
probability that it will rain on exactly 2 of these 7 days?
Answers
The probability that it will rain on exactly 2 out of the 7 days is approximately 0.249, or 24.9%.
How to find the probability that it will rain on exactly 2 of these 7 daysTo find the probability of it raining on exactly 2 out of 7 days, we can use the binomial probability formula.
The binomial probability formula is given by:
\(\[ P(X = k) = \binom{n}{k} \cdot p^k \cdot (1-p)^{n-k} \]\)
In this case, we want to find the probability of raining on exactly 2 out of 7 days, so \(\( n = 7 \), \( k = 2 \), and \( p = 0.4 \).\)
Using the formula, we can calculate the probability as follows:
\(\[ P(X = 2) = \binom{7}{2} \cdot (0.4)^2 \cdot (1-0.4)^{7-2} \]\)
Calculating the values:
\(\[ \binom{7}{2} = \frac{7!}{2! \cdot (7-2)!} = 21 \]\)
\(\[ (0.4)^2 = 0.16 \]\)
\(\[ (1-0.4)^{7-2} = 0.6^5 = 0.07776 \]\)
Plugging these values into the formula:
P(X = 2) = 21 * 0.16 * 0.07776
Calculating the result:
P(X = 2) ≈ 0.249
Therefore, the probability that it will rain on exactly 2 out of the 7 days is approximately 0.249, or 24.9%.

Morganton Company makes one product and it provided the following information to help prepare the master budget:
The budgeted selling price per unit is $60. Budgeted unit sales for June, July, August, and September are 8,600, 17,000, 19,000, and 20,000 units, respectively. All sales are on credit.
Thirty percent of credit sales are collected in the month of the sale and 70% in the following month.
The ending finished goods inventory equals 25% of the following month’s unit sales.
The ending raw materials inventory equals 10% of the following month’s raw materials production needs. Each unit of finished goods requires 5 pounds of raw materials. The raw materials cost $2.40 per pound.
Thirty five percent of raw materials purchases are paid for in the month of purchase and 65% in the following month.
The direct labor wage rate is $14 per hour. Each unit of finished goods requires two direct labor-hours.
The variable selling and administrative expense per unit sold is $1.80. The fixed selling and administrative expense per month is $67,000.
5. If 96,250 pounds of raw materials are needed to meet production in August, how many pounds of raw materials should be purchased in July?
Answers
Raw materials purchases in July - Payment for raw materials purchases in July = Desired ending raw materials inventory for July
X pounds - 0.35 * X pounds = 9,500 pounds
Solving this equation will give us the value of X, which represents the pounds of raw materials that should be purchased in July.
To determine the number of pounds of raw materials that should be purchased in July, we need to calculate the raw materials production needs for August and then consider the inventory policies given in the information provided.
Each unit of finished goods requires 5 pounds of raw materials. The budgeted unit sales for August are 19,000 units. Therefore, the raw materials production needs for August would be 19,000 units multiplied by 5 pounds per unit, which equals 95,000 pounds.
The ending raw materials inventory equals 10% of the following month’s raw materials production needs. Therefore, the desired ending raw materials inventory for July would be 10% of 95,000 pounds, which is 9,500 pounds.
To calculate the raw materials purchases for July, we need to consider the payment terms provided. Thirty-five percent of raw materials purchases are paid for in the month of purchase and 65% in the following month.
Let's assume the raw materials purchases for July are X pounds. Then the payment for 35% of X pounds will be made in July, and the payment for 65% of X pounds will be made in August.
The payment for raw materials purchases in July (35% of X pounds) will be:
0.35 * X pounds
The payment for raw materials purchases in August (65% of X pounds) will be:
0.65 * X pounds
Since the raw materials purchases for July should cover the desired ending raw materials inventory for July (9,500 pounds), we can set up the following equation:
Raw materials purchases in July - Payment for raw materials purchases in July = Desired ending raw materials inventory for July
X pounds - 0.35 * X pounds = 9,500 pounds
Solving this equation will give us the value of X, which represents the pounds of raw materials that should be purchased in July.

What is the measure in radians for the central angle of a circle whose radius is 8 cm and intercepted arc length is 5.6 cm? Enter your answer as a decimal in the box. radians
Answers
The measure in radians for the central angle is approximately 0.7 radians.
To find the measure in radians for the central angle of a circle, we can use the formula:
θ = s / r
where θ is the central angle in radians, s is the intercepted arc length, and r is the radius of the circle.
In this case, the radius is given as 8 cm and the intercepted arc length is 5.6 cm.
Plugging these values into the formula, we have:
θ = 5.6 cm / 8 cm
Simplifying the expression:
θ = 0.7
We may use the following formula to get the centre angle of a circle's measurement in radians:
= s / r
s is the length of the intercepted arc, r is the circle's radius and is the centre angle in radians.
The intercepted arc length in this instance is 5.6 cm, while the radius is specified as 8 cm.
When these values are plugged into the formula, we get:
θ = 5.6 cm / 8 cm
Condensing the phrase:
θ = 0.7

If Mira had spent the same total amount of time, but spent an equal amount of time on each problem, how many minutes would each problem have taken?
Answers
If Mira had spent the same total amount of time but an equal amount of time on each problem, each problem would have taken around 2.36 minutes.
In the given plot, Mira spent varying amounts of time on each of the 55 math problems. To find out how many minutes each problem would have taken if Mira had spent an equal amount of time on each problem, we need to calculate the total time she spent and divide it by the number of problems.
Looking at the plot, we can estimate the total time Mira spent by counting the dots above each tick mark and multiplying them by the corresponding time interval. Let's break it down step by step:
The tick marks on the plot are at 7, 7.5, 8, 8.5, 9, 9.5, and 10 minutes per problem.
There are 2 dots above the unlabeled tick mark between 8 and 8.5 minutes per problem. We can assume it represents 8.25 minutes.
There are 3 dots above the 9.5 minutes per problem tick mark.
Now, let's calculate the total time Mira spent:
(7 * 2) + (7.5 * 2) + (8 * 2) + (8.25 * 2) + (9 * 2) + (9.5 * 3) + (10 * 2) = 129.5 minutes.
Since Mira spent a total of 129.5 minutes on 55 problems, each problem would have taken approximately 2.36 minutes (rounded to two decimal places) if she had spent an equal amount of time on each problem.
