Suppose the supply for a certain textbook is given by p=1/4 q^2 and demand is given by p=-1/4 q^2+40, where p is the price and q is the quantity.
(a) How many books are demanded at a price of $5?
(b) How many books are supplied at a price of $5?
(c) Graph the supply and demand functions on the same axes.

Answers

Answer 1

Approximately 11.83 books are demanded at a price of $5 and approximately 4.47 books are supplied at a price of $5.

(a)To find the quantity of books demanded at a price of $5, we need to substitute the price value (p) into the demand function and solve for the quantity (q).

Given:

Demand function: p = -1/4 q^2 + 40

Price (p) = $5

Substituting the price value into the demand function:

5 = -1/4 q^2 + 40

To isolate q^2, we subtract 40 from both sides:

-35 = -1/4 q^2

Now, let's solve for q^2:

q^2 = (-35) / (-1/4)

q^2 = (-35) * (-4)

q^2 = 140

Taking the square root of both sides to solve for q:

q = √(140)

q ≈ 11.83

Therefore, approximately 11.83 books are demanded at a price of $5.

(b) To find the quantity of books supplied at a price of $5, we need to substitute the price value (p) into the supply function and solve for the quantity (q).

Given:

Supply function: p = 1/4 q^2

Price (p) = $5

Substituting the price value into the supply function:

5 = 1/4 q^2

To isolate q^2, we multiply both sides by 4:

20 = q^2

Now, let's solve for q:

q = √(20)

q ≈ 4.47

Therefore, approximately 4.47 books are supplied at a price of $5.

(c) Graph the supply and demand functions on the same axes:

To graph the supply and demand functions on the same axes, we will use the price (p) on the vertical axis and the quantity (q) on the horizontal axis.

Let's plot the points for both the supply and demand functions and then connect them to visualize the graph.

Supply function: p = 1/4 q^2

Demand function: p = -1/4 q^2 + 40

Here is the graph:

     |

40   |                             *

     |                          *

     |                       *

     |________________________________________

       0    |    4.47        |       11.83      q

            Supply       Dema

The horizontal axis represents the quantity (q) of books, and the vertical axis represents the price (p). The supply curve is upward sloping, indicating that as the quantity increases, the price also increases. The demand curve is downward sloping, indicating that as the quantity increases, the price decreases. The intersection of the supply and demand curves represents the equilibrium point where the quantity supplied equals the quantity demanded.

A cargo ship left port a and is headed across the ocean to shipping port b. After one month, the ship stopped at a refueling station along a path described by a vector with components leftanglebracket 14, 23 rightanglebracket. After another month, on the same path, the ship reached port b, twice the distance from port a as the fueling station. What are the characteristics of the vector representing the path of the ship?.

Answers

Answer:

Step-by-step explanation:

The vector representing the path of the ship from port A to the refueling station has components <14, 23>, and the vector representing the path from the refueling station to port B has twice the magnitude as the vector from port A to the refueling station.

To find the characteristics of the vector representing the path of the ship from port A to port B, we can add the two vectors together.

The sum of two vectors <a, b> and <c, d> is given by <a+c, b+d>. Therefore, the vector representing the path of the ship from port A to port B is given by:

<14, 23> + 2*<14, 23> = <14+214, 23+223> = <42, 69>

The vector representing the path of the ship from port A to port B is <42, 69>. This vector has a magnitude of √(42^2 + 69^2) = √(1764 + 4761) = √(6525) = 81 and a direction given by the angle theta, where tan(theta) = 69/42.

The elongation α

(see exercise 65 in section 6.2 ). at a certain time the elongation of venus is found to be 39.4∘.
find the possible distances from the earth to venus at that time in astronomical units (au).

Answers

The distance from the earth to venus is an illustration of the sine ratio

The distance from the earth to venus at that time is 1.12 au

How to determine the possibe distance?

See attachment for the diagram that illustrates the complete question.

Start by calculating the angle V using the following sine ratio

SE/sin(V) = VS/sin(E)

This gives

1/sin(V) = 0.723/sin(39.4)

Take the inverse of both sides

sin(V)/1 = sin(39.4)/0.723

Evaluate the quotient

sin(V) = 0.8779

Take the arcsin of both sides

V = 61.4

Calculate the measure of angle S

<S + <V + <E = 180

This gives

<S  = - <V - <E + 180

Substitute known values

<S  = -61.4 - 39.4 + 180

<S  = 79.2

The distance (VE) is then calculated using the following sine ratio

VE/sin(S) = VS/sin(E)

This gives

VE/sin(79.2) = 0.723/sin(39.4)

Multiply bot sides by sin(79.2)

VE = sin(79.2) * 0.723/sin(39.4)

Evaluate the product

VE = 1.12

Hence, the distance from the earth to venus at that time is 1.12 au

Which of the following is not true of a normal curve?a. It is skewed.b. It is a probability distribution.c. Its total area contains 100% of the cases.d. The mode, median, and mean are identical.

Answers

The statement that is not true of a normal curve is a. It is skewed.

A normal curve, also known as a bell curve or Gaussian distribution, is a symmetric probability distribution.

This means that it is not skewed, and it has a shape that is roughly like a bell. The curve is defined by its mean and standard deviation, which determine its center and spread. The total area under the curve represents 100% of the cases or observations in the distribution. The area under the curve between any two points represents the proportion of cases falling between those points. The mode, median, and mean are identical in a normal curve, which means that they all represent the center of the distribution. The mode is the most frequently occurring value, the median is the middle value, and the mean is the arithmetic average of all the values.

In summary, a normal curve is a symmetric probability distribution that is not skewed, and its total area contains 100% of the cases.

suppose that y follow a multivariate normal distribution. then, what are the mean and covariance matrix of y ?

Answers

The value of mean, variance and covariance matrix is illustrated in following solution as

\(V(\frac{X}{X'} )=\left[\begin{array}{ccc}\frac{1}{12} &\frac{1}{12} \\\frac{1}{12} &\frac{4}{45} \\\end{array}\right]\)

What is mean and covariance?

The mean vector consists of the means of each variable and the variance-covariance matrix consists of the variances of the variables along the main diagonal and the covariances between each pair of variables in the other matrix positions. with \bar{x} and \bar{y} denoting the means of X and Y, respectively.

Mean and variance is a measure of central dispersion. Mean is the average of given set of numbers. The average of the squared difference from the mean is the variance. Central dispersion tells us how the data that we are taking for observation are scattered and distributed.

To find the mean, variance and covariance matrix of a random vector

\(\left[\begin{array}{ccc}X\\X'\\\end{array}\right]\) X~ U(0,1)

\(E(X')=\int\limits^1_0 {r} \, dr = \frac{1}{r+1}\)

where, r = 1 , 2, 3...

Now,

\(E(X) = \frac{1}{2}\\ \\E(X^2) = \frac{1}{3}\\ \\E(X^3) =\frac{1}{4}\\\)

\(E(X^4)=\frac{1}{5}\)

So, cov(X , X') =

\(E(X^3)-E(X).E(X')\\\\=\frac{1}{4} -\frac{1}{2}.\frac{1}{3}\\ \\ =\frac{1}{12}\)

\(Var(X) = E(X^4) -E'(X')\\\\\frac{1}{5}-\frac{1}{9}\\ \\ \frac{4}{45}\)

Hence,

\(V(\frac{X}{X'} )=\left[\begin{array}{ccc}\frac{1}{12} &\frac{1}{12} \\\frac{1}{12} &\frac{4}{45} \\\end{array}\right]\)

Write an equation in slope-intercept form.

Answers

Given:

The table of values.

To find:

The equation in slope intercept form.

Solution:

From the given table it is clear that the line passes through the points (5,17), (8,41) and (12,73).

Consider any two points from the table, i.e., (5,17) and (8,41). So, the equation of line is

\(y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\)

\(y-17=\dfrac{41-17}{8-5}(x-5)\)

\(y-17=\dfrac{24}{3}(x-5)\)

\(y-17=8(x-5)\)

\(y=8x-40+17\)

\(y=8x-23\)

Therefore, the equation of line in slope intercept form is \(y=8x-23\).

For the preceding problem you should find that there are significant differences among the three treatments. Onee reason for the significance is that the sample variances are relatively small. The following data have the same sample means that appeared in the preceding question, but the SS values within each sample are doubled
Calculate the sample variance for each of the three samples These values are the variances in the previous question (12.00, 13.00, and 8.00)

Answers

The SS value for the first, second and third sample is 24, 26 and 18 respectively. Upon dividing the SS value by the sample size minus one, sample variance can be derived.

In the previous question, there were significant differences among the three treatments, partially due to the relatively small sample variances. Now, with the SS (sum of squares) values within each sample doubled, we need to calculate the new sample variances. The values provided in the previous question were 12.00, 13.00, and 8.00.

To calculate the sample variance for each of the three samples, we utilize the formula for variance, which is the sum of squared deviations from the mean divided by the sample size minus one.

For the first sample with a previous variance of 12.00, if the SS value is doubled, the new SS value would be 24.00. To calculate the new sample variance, we divide this SS value by the sample size minus one.

Similarly, for the second sample with a previous variance of 13.00, the doubled SS value would be 26.00. Again, we divide this SS value by the sample size minus one to calculate the new sample variance.

Lastly, for the third sample with a previous variance of 8.00, the doubled SS value would be 16.00. We divide this SS value by the sample size minus one to obtain the new sample variance.

By performing these calculations, we can determine the new sample variances for each of the three samples, which will reflect the changes resulting from the doubled SS values within each sample.

The restaurant’s research indicates that during a given year 80% of these freezers need no repairs, 11% needed to be serviced once, 5% twice, 4% three times, and none required more than three repairs.
a. Find the expected number of repairs for this freezer per year.
b. Find the standard deviation of the number of repairs per year.
c. What are the mean and standard deviation of the restaurant’s annual expense with the service contract for the freezer?

Answers

(a) Expected number of repairs per year is 0.33 (b) Standard deviation of number of repairs per year is 0.749, (c) The mean and standard deviation of annual expense are $136.55 and $26.217 respectively.

What is Standard Deviation?

Standard deviation is a measure in statistics which measures the amount of deviation a set of data has with respect to their mean.

(a) Expected number of repairs for the freezer per year is the sum of the product of number of repairs to their probability.

E(Repairs) = (0 × 0.80) + (1 × 0.11) + (2 × 0.05) + (3 × 0.04)

                 = 0.33

(b) Standard deviation of number of repairs per year can be calculated as,

SD(Repairs) = \(\sqrt{[(0 - 0.33)^{2}(0.8)]+[(1-0.33)^{2}(0.11)] + [(2-0.33)^{2}(0.05)]+[(3-0.33)^{2}(0.04)] }\)

= √ (0.5611)

= 0.749

(c) Mean of the restaurant's annual expense with service contract is,

Mean = Expected cost = $125 + ($35 × 0.33) = $136.55

Standard deviation of the restaurant's annual expense with service contract is,

SD = \(\sqrt{35^{2}(0.5611) }\) = 35 × 0.759 = 26.217

Hence the expected number of repairs is 0.33, standard deviation of number of repairs is 0.749, mean and standard deviation of annual expense is $136.55 and $26.217 respectively.

The probability of selecting a piece of pottery is 7/26, and when converted to a percentage and rounded to the nearest whole percent, it is approximately 27%.

An archaeologist uncovers 26 artifacts from a site. The types of artifacts are shown below. The horizontal axis represents tools, pottery, and coins. The vertical axis represents the number of artifacts and ranges from 0 to 16, in increments of 2. The number of artifacts of tools is 14. The number of artifacts of pottery is 7. The number of artifacts of coins is 5.

What is the probability that a piece of pottery is selected?

The total number of artifacts at the site = 26

Number of pottery artifacts = 7

Probability of selecting a piece of pottery = Number of pottery artifacts/Total number of artifacts

Probability of selecting a piece of pottery = 7/26

If we want to express this probability in a percentage, we can convert it by multiplying it by 100.

without using symmetry, determine a definite integral that represents the area of the region enclosed by r = 1 sin θ .

Answers

The definite integral that represents the area of the region enclosed by the polar curve r = 1 sin θ is ∫[a, b] 1/2 r^2 dθ

To determine the definite integral that represents the area of the region, we integrate the expression 1/2 r^2 with respect to θ over the interval [a, b], where a and b are the limits of the region.

In this case, the polar curve r = 1 sin θ represents a circle with radius 1 centered at the origin. As θ varies from 0 to π, the curve traces half of the circle in the positive direction. To find the area of the region enclosed by this curve, we integrate the expression 1/2 r^2 over this interval.

The expression 1/2 r^2 represents the area of a sector of the circle with radius r and central angle θ. Integrating this expression with respect to θ gives us the total area enclosed by the curve.

By evaluating the definite integral over the interval [a, b], we can find the area of the region enclosed by the polar curve r = 1 sin θ.

Answer:

94 ft

Step-by-step explanation:

A dude ranch in Texas charges each customer y dollars to gohorseback riding based on the equation y=10x+20, where xrepresents the number of hours they go horseback riding.5. How much will it cost for one person to go horseback riding for 3hours?6. How much will it cost for a family of 4 to go horseback riding for2 hours?7. What does the y intercept mean in the equation?

Answers

Answer:

(a)$50

(b)$160

Explanation:

The equation that represents the charge per customer is:

\(\begin{gathered} y=10x+20 \\ x=\text{number of hours they go horseback riding.} \end{gathered}\)

Part 5

When one person goes horseback riding for 3 hours.

x=3

\(\begin{gathered} y=10(3)+20 \\ =30+20 \\ =\$50 \end{gathered}\)

Part 6

If one person goes horseback riding for 2 hours:

\(\begin{gathered} y=10(2)+20 \\ =20+20 \\ =\$40 \end{gathered}\)

Since they are a family of 4, the cost will be:

\(\begin{gathered} 4y=4\times40 \\ =\$160 \end{gathered}\)

Part 7

In the equation:

\(y=10x+20\)

The y-intercept, $20 represents the cost of entry to the ranch. It means that even if a person does not go horseback riding, they will still pay the $20.

Use propositional logic to prove that the argument is valid. Do not use truth tables (A + B) ^ (C V -B) ^(-D-->C) ^ A D Please use the following substitute operators during your quiz: ^: &
v: I
¬: !
-->: ->

Answers

To prove that the argument is valid using propositional logic, we can apply logical rules and deductions. Let's break down the argument step by step:

(A + B) ^ (C V -B) ^ (-D --> C) ^ A ^ D

We will represent the proposition as follows:

P: (A + B)

Q: (C V -B)

R: (-D --> C)

S: A

T: D

From the given premises, we can deduce the following:

P ^ Q (Conjunction Elimination)

P (Simplification)

Now, let's apply the rules of disjunction elimination:

P (S)

A + B (Simplification)

Next, let's apply the rule of disjunction introduction:

C V -B (S ^ Q)

Using disjunction elimination again, we have:

C (S ^ Q ^ R)

Finally, let's apply the rule of modus ponens:

-D (S ^ Q ^ R)

C (S ^ Q ^ R)

Since we have derived the conclusion C using valid logical rules and deductions, we can conclude that the argument is valid.
