If the company incurs a loss of £4 when it produces a quantity of 2 and the production surplus when the company produces a quantity of 2 is £4.
(a) To calculate the profit of the company, we need to subtract the total cost from the total revenue. The total revenue is given by p * q, where p is the price and q is the quantity produced.
Total revenue = p * q = 4 * 2 = 8
The total cost function is C(q) = 8 + q^2. Substituting q = 2 into the cost function, we have:
Total cost = C(2) = 8 + 2^2 = 8 + 4 = 12
Profit = Total revenue - Total cost = 8 - 12 = -4
Therefore, the company incurs a loss of £4 when it produces a quantity of 2.
(b) The producer surplus can be calculated by subtracting the variable cost from the total revenue. Since the unit cost of capital and the unit wage are both equal to 1, the variable cost is equal to the wage cost, which is L * w. Substituting L = q^2 and w = 1, we have:
Variable cost = L * w = (q^2) * 1 = q^2
Producer surplus = Total revenue - Variable cost = p * q - q^2 = 4 * 2 - 2^2 = 8 - 4 = 4
Therefore, the producer surplus when the company produces a quantity of 2 is £4.

Answer:
C
Step-by-step explanation:
We want to find which model shows two equal expressions. We know that the value of x is 6. That being said, on the left side of each equation, plug in 6 for every "x" you see. Then, add the values on both sides. If they're equal, that's your answer.
For example:
In choice A, we see two x's, so we plug in 6 for them both and add them. That's 12 on the left side. On the other side of the equation, we have 7 "1" boxes, which simply just means add them, so that's 7 on the other side. 12 does not equal 7, therefore A is not the answer. However, for choice C, we are given x, which we know is 6, and a "1" box, which simply means 6 + 1, which is 7. On the other side of this equation, we have 7 "1" boxes, so that's 7. The equation becomes 7 = 7, which is true, so that is our answer.

3. Given a normal distribution of test scores from that same statistics class where the mean is 80 and the standard deviation is 7.5, determine BY HAND what percent of the scores were 78 or less. Also, what percent of scores were 85 or better?
The percent of the scores that were 85 or better is 25.14%.
The percent of the scores that were 78 or less is 39.25%.
The percent of the scores that were 85 or better is 25.14%.
Given a normal distribution of test scores from that same statistics class where the mean is 80 and the standard deviation is 7.5, we are to determine what percent of the scores were 78 or less and what percent of the scores were 85 or better.
Below are the steps to determine what percent of the scores were 78 or less.
Step 1: Determine the Z-score
To determine the Z-score, we use the formula
Z = (X - μ) / σ
Where X is the score, μ is the mean and σ is the standard deviation
Z = (78 - 80) / 7.5
Z = -0.27
Step 2: Use the Z-table to determine the percentage
Using the Z-table, we can find the percentage of scores that lie below Z = -0.27 which is 0.3925 or 39.25%
Therefore, the percent of the scores that were 78 or less is 39.25%.
Below are the steps to determine what percent of the scores were 85 or better.
Step 1: Determine the Z-score
To determine the Z-score, we use the formula Z = (X - μ) / σ
Where X is the score, μ is the mean and σ is the standard deviation
Z = (85 - 80) / 7.5
Z = 0.67
Step 2: Use the Z-table to determine the percentage
Using the Z-table, we can find the percentage of scores that lie above Z = 0.67
Which is 0.2514 or 25.14%

A recent Gallup poll found large differences in the type of household chores done by wives and husbands.1 Wives still do most of the indoor household chores. Husbands still tend to do more work outside and with family cars. The simulated data in this problem are based on the results of this poll.
Suppose we wish to demonstrate that there is a difference between the proportions of wives and husbands who do laundry at home. From a random sample of 66 randomly selected wives, we observe 44 who do laundry at home. From a random sample of 46 husbands, we observe 18 who do laundry at home.
Test the claim that the proportion of wives, p1 , who do laundry at home is different from the proportion of husbands, p2 , who do laundry at home. Use a 1% significance level.
Answer : There is enough evidence to suggest that a higher proportion of wives do laundry at home compared to the proportion of husbands who do laundry at home.
Explanation:
The null hypothesis is that the proportion of wives and husbands who do laundry at home is the same. The alternative hypothesis is that the proportion of wives and husbands who do laundry at home is different.
Mathematically, null and alternative hypotheses are given below. H0: P1 - P2 = 0H1: P1 - P2 ≠ 0 where P1 is the proportion of wives who do laundry at home and P2 is the proportion of husbands who do laundry at home. Let α = 0.01 be the significance level. Therefore, α/2 = 0.005 and the Zα/2 value for the two-tailed test is ±2.58.
The point estimate of the difference in the proportions is:Point estimate, PE = P1 - P2 = (44/66) - (18/46) = 0.6667 - 0.3913 = 0.2754
The standard error of the difference in the proportions is: SE = sqrt{(P1(1 - P1)/n1) + (P2(1 - P2)/n2)} = sqrt{[(44/66)(22/66)/65] + [(18/46)(28/46)/45]} = 0.1033
The test statistic is given by:Z = (PE - 0) / SE = 0.2754 / 0.1033 = 2.6641
Since the absolute value of the test statistic is greater than the Zα/2 value, we reject the null hypothesis and conclude that the proportion of wives who do laundry at home is different from the proportion of husbands who do laundry at home at a 1% significance level. Therefore, there is enough evidence to suggest that a higher proportion of wives do laundry at home compared to the proportion of husbands who do laundry at home.

What are the six trigonometric ratios?Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
From that angle (suppose its measure is θ),
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]
For this case, we've to find the length of the fencing she needs to cover her garden.
Length of fencing needed = Perimeter of the considered right triangle = sum of its sides' lengths
Using the image attached below, from the perspective of angle A which is of 50 degrees from inside, we get:
|AB| = base length = 5 meters (given)|BC| = perpendicular length = p meters (say)|AC| = hypotenuse length = h meters (say)Using tangent ratio,[tex]\tan(m\angle A) = \tan(50^\circ) = \dfrac{p}{5}\\\\p = 5 \tan(50^\circ) \approx 5.96 \: \rm m[/tex]
Using sin ratio,[tex]\sin(m\angle A) = \sin(50^\circ) = \dfrac{p}{h}\\\\h = \dfrac{p}{\sin(50^\circ)} \approx \dfrac{5.96}{\sin(50^\circ)} \approx 7.78 \: \rm m[/tex]
Thus, perimeter of the triangle = 5 + p + h ≈ 18.74 m ≈ 19 m
Thus, the amount of fence that Priya would need (in meters) is 19 meters approximately.

The given function f(x) = 9 + √2 - 3 is an expression that does not depend on the variable x. Therefore, it represents a constant value.
To evaluate the function, we can simplify the expression by combining like terms:
f(x) = 9 + √2 - 3
Combining the constants 9 and -3, we have:
f(x) = 6 + √2
Thus, the value of the function f(x) is a constant, which is 6 + √2.

Number of participants = 274 Number of groups = 5 SSD = 1 SSW = 192 What is the mean squares within?
The mean squares within is 0.7130044843.
The formula to calculate the mean squares within is given below:
Mean squares within (MSW) = SSW / (n - k), where n = Total number of observations, k = Total number of groups.
Here, Number of participants = 274, Number of groups = 5, SSD = 1, SSW = 192.
Now, the value of n and k can be calculated using the formula given below:
n = Number of participants = 274, k = Number of groups = 5.
Let's substitute the values in the formula of mean squares within:
Mean squares within (MSW) = SSW / (n - k)
MSW = 192 / (274 - 5)
MSW = 192 / 269
MSW = 0.7130044843
Hence, the mean squares within is 0.7130044843.
