You can be​ 90% confident that the population mean price of the stock is between the bounds of the​ 90% confidence​ interval, and​ 95% confident for the​ 95% interval.

Given data ,

The problem states that a random sample of 43 business days was taken, and the mean closing price of the stock in that sample was $112.15. The population standard deviation is assumed to be $9.95. Based on this information, a confidence interval can be calculated for the population mean.

Now , A wider interval results from a greater confidence level since it calls for more assurance.

If you compare the offered alternatives, option C accurately indicates that you can have a 90% confidence interval for the population mean price of the stock being inside the boundaries, and a 95% confidence interval. Because a 90% confidence interval demands more assurance than a 95% confidence interval, it is smaller. As a result, the population mean is more likely to fall inside the 90% confidence interval's boundaries.

The triangular prism has 3 cylindrical holes with a diameter of 4 cm. The volume of each hole is approximately 60π cubic centimeters, so the total volume of all three holes is about 180π cubic centimeters.

To find the volume of cylindrical holes in the triangular prism, we need to calculate the volume of one cylinder and then multiply it by three (since there are three cylindrical holes).

Volume of one cylinder = πr²h, where r is the radius of the cylinder and h is the height.

Given the diameter of the cylindrical hole is 4 cm, we can find the radius by dividing it by 2

radius (r) = 4 cm ÷ 2 = 2 cm

The height of the cylinder is the same as the length of the prism, which is 15 cm.

Volume of one cylinder = π(2 cm)² × 15 cm

= 60π cm³

Since there are three cylindrical holes, the total volume of the holes is

Total volume of cylindrical holes = 3 × 60π cm³

= 180π cm³

Therefore, the volume of the three cylindrical holes is 180π cubic centimeters.

The correct answer is: It is necessary to apply both the decomposition and the augmentation rules to F in order to form a minimal cover.

To form a minimal cover of a set of functional dependencies, we need to apply the decomposition rule, which involves breaking down each dependency in F into its simplest form, and the augmentation rule, which involves adding any missing attributes to the right-hand side of each dependency. In this case, we need to apply both rules to F to obtain a minimal cover.

For example, applying the decomposition rule to UVX->UW yields two dependencies: UV->UW and UX->UW. Applying the augmentation rule to UX->ZV yields UX->ZVY. Continuing in this way, we can obtain a minimal cover for F, which is:

UV->UW
UX->ZVY
VU->Y

The decision complexity advantage for 10 decisions with two alternatives compared to one decision with 20 alternatives is 3.31. This can be answered by the concept of Log.

To calculate the decision complexity advantage, we need to first plug in the given values for a and b into the formula RT = a + b log2(N), where N is the number of alternatives.

For 10 decisions with two alternatives each, N = 2¹⁰ = 1024. Thus, RT = 1 + 2 log2(1024) = 22 seconds.

For one decision with 20 alternatives, N = 20. Thus, RT = 1 + 2 log2(20) = 6.64 seconds.

The decision complexity advantage is calculated by taking the ratio of the RT values: 22/6.64 = 3.31. This means that making 10 decisions with two alternatives each is 3.31 times faster than making one decision with 20 alternatives.

Therefore, the decision complexity advantage for 10 decisions with two alternatives compared to one decision with 20 alternatives is 3.31.

Answer:

The pressure exerted by the box on the shelf is given by the formula:

Pressure = Force / Area

where Pressure is measured in Newtons per square meter (N/m^2), Force is measured in Newtons (N), and Area is measured in square meters (m^2).

We are given that the pressure exerted by the box on the shelf is 200 N/m and the force that the box exerts on the shelf is 140 N. Using the formula above, we can solve for the area of the base of the box as follows:

200 N/m = 140 N / Area

Simplifying the equation above, we can multiply both sides by the Area to get:

Area * 200 N/m = 140 N

Dividing both sides by 200 N/m, we get:

Area = 140 N / 200 N/m

Simplifying the right-hand side, we get:

Area = 0.7 m^2

Therefore, the area of the base of the box is 0.7 square meters, or 0.7 m^2 to 1 decimal place.

Answer:

0.7 m²

Step-by-step explanation:

The pressure exerted by the box on the shelf is defined as the force per unit area, so we can use the formula:

[tex]\boxed{\sf Pressure = \dfrac{Force}{Area}}[/tex]

We need to determine the area of the base of the box, so we can rearrange the formula to solve for area:

[tex]\boxed{\sf Area= \dfrac{Force}{Pressure}}[/tex]

Given values:

Substitute the given values into the formula:

[tex]\implies \sf Area = \dfrac{140\;N}{200\;N\;m^{-2}}[/tex]

[tex]\implies \sf Area = \dfrac{140}{200}\;m^2[/tex]

[tex]\implies \sf Area = 0.7\;m^2[/tex]

Therefore, the area of the base of the box is 0.7 square meters.

The solution of the quadratic equation  4e² - 15e = -4 in the exact form is e = (15 + √161)/8 or e = (15 - √161)/8

To solve the quadratic equation 4e² - 15e = -4, we can rearrange it into standard form as follows,

4e² - 15e + 4 = 0. We can then use the quadratic formula, which states that for an equation in the form ax² + bx + c = 0, the solutions are given by,

x = (-b ± √(b² - 4ac)) / 2a

Applying this formula to our equation, we have,

e = (-(-15) ± √((-15)² - 4(4)(4))) / 2(4)

Simplifying this expression, we get,

e = (15 ± √(225 - 64)) / 8

e = (15 ± √161) / 8

Therefore, the solutions to the equation 4e² - 15e = -4 are:

e = (15 + √161) / 8 or e = (15 - √161) / 8

Your answer: The elasticity of the demand function 2p 3q = 90 at the price p = 15 is -0.5.

To find the elasticity of the demand function, we need to use the following formula:

Elasticity = (dq/dp) * (p/q)

where dq/dp is the derivative of q with respect to p, and (p/q) is the ratio of the two variables at a given point.

First, we need to solve the demand function for q in terms of p:

2p + 3q = 90

3q = 90 - 2p

q = (90 - 2p)/3

Next, we need to find the derivative of q with respect to p:

dq/dp = (-2/3)

Finally, we can plug in the values for p and q to find the elasticity at p = 15:

q = (90 - 2(15))/3 = 20

(p/q) = 15/20 = 0.75

Elasticity = (-2/3) * (15/20) = -0.5

Therefore, the elasticity of the demand function 2p + 3q = 90 at the price p = 15 is -0.5. This means that a 1% increase in price would lead to a 0.5% decrease in quantity demanded.

The expression for the temperature of the coffee at time t is:

T(t) = 20 ± (T0 - 20) [tex]e^{(-kt) }[/tex]

What is Algebraic expression ?

An algebraic expression is a combination of variables, numbers, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions can be used to represent a wide range of mathematical relationships and formulas in a concise and flexible manner.

The differential equation we discussed in Exercise 9.2.28 is:

dT÷dt = -k(T-20)

where T is the temperature of the coffee in Celsius, t is time in minutes, and k is a constant that depends on the properties of the coffee cup and the room.

To solve this differential equation, we need to separate the variables and integrate both sides.

dT  ÷ (T-20) = -k dt

Integrating both sides:

ln|T-20| = -kt + C

where C is an arbitrary constant of integration.

To solve for T, we exponentiate both sides:

|T-20| =[tex]e^{(-kt + C) }[/tex]

Using the property of absolute values, we can write:

T-20 = ± [tex]e^{(-kt + C) }[/tex]

or

T = 20 ± [tex]e^{(-kt + C) }[/tex]

We can determine the sign of the exponential term by specifying the initial temperature of the coffee. If the initial temperature is above 20°C, then the temperature of the coffee will decay towards 20°C, and we take the negative sign in the exponential term. If the initial temperature is below 20°C, then the temperature of the coffee will increase towards 20°C, and we take the positive sign in the exponential term.

To determine the value of the constant C, we use the initial temperature of the coffee. If the initial temperature is T0, then we have:

T(t=0) = T0 = 20 ± [tex]e^{C }[/tex]

Solving for C, we get:

C = ln(T0 - 20) if we took the negative sign in the exponential term

or

C = ln(T0 - 20) if we took the positive sign in the exponential term.

Therefore, the expression for the temperature of the coffee at time t is:

where a, b, c, and d are constants.

We can write this system as X' = AX, where X =[tex][x, y]^T[/tex] and A is the 2x2 matrix:

To find a fundamental system of differential equations, we need to find the eigenvalues and eigenvectors of A.

The characteristic equation of A is:

The eigenvalues of A are the roots of the characteristic equation:

λ1,2 = (a+d ± [tex]\sqrt^(a+d)^2[/tex] - 4(ad-bc))) / 2

The eigenvectors of A are the solutions to the equation (A - λI)v = 0, where v is a non-zero vector.

If λ1 and λ2 are distinct eigenvalues, then the eigenvectors corresponding to each eigenvalue form a fundamental system of differential equations. Specifically, if v1 and v2 are eigenvectors corresponding to λ1 and λ2, respectively, then the solutions to the differential equation X' = AX are given by:

X(t) = c1 [tex]e^\((\lambda 1t)[/tex] v1 + c2 [tex]e^\((\lambda 1t)[/tex] v2

where c1 and c2 are constants determined by the initial conditions.

If λ1 and λ2 are not distinct (i.e., they are repeated), then we need to find a set of linearly independent eigenvectors to form a fundamental system of differential equations. In this case, we use the method of generalized eigenvectors.

(b) To rewrite the system of differential equations as one 2nd order linear differential equation, we can differentiate the first equation with respect to t to obtain:

Substituting the second equation into the last expression, we get:

d²x/dt² = (a² + bc)x + (ab + bd)(-cx + d(dx/dt))

9(x-1)^2 = 9

(x-1)^2 = 1

x-1 = ±1

x = 2 or 0

Now we can do the same for the y terms:

y^2 - 6y = 0

y^2 - 6y + 9 - 9 = 0

(y-3)^2 - 9 = 0

(y-3)^2 = 9

y-3 = ±3

y = 6 or 0

So the center of the ellipse is (1, 3), the major axis is along the x-axis with a length of 2a = 2√(9/1) = 6, and the minor axis is along the y-axis with a length of 2b = 2√(1/9) = 2/3.

The vertices are the points on the major axis that are farthest from the center. Since the major axis is along the x-axis, the vertices will be (1±3, 3), or (4, 3) and (-2, 3).

To find two points on the minor axis, we can use the center and the length of the minor axis. Since the minor axis is along the y-axis, we can add or subtract the length of the minor axis from the y-coordinate of the center to find the two points. Therefore, the two points on the minor axis are (1, 3±1/3), or approximately (1, 10/3) and (1, 8/3).

Step-by-step explanation:

The slope of the parametric curve x=-[tex]2t^3[/tex]+7, y=3t² at the point corresponding to t is -1 divided by t.

To find the slope of the parametric curve x=-[tex]2t^3[/tex]+7, y=3t², we need to take the derivative of y with respect to x.

To do this, we can use the chain rule:

(dy/dx) = (dy/dt) / (dx/dt)

where (dx/dt) is the derivative of x with respect to t, and (dy/dt) is the derivative of y with respect to t.

Taking the derivatives, we get:

dx/dt = -6t²

dy/dt = 6t

Substituting these values, we get:

(dy/dx) = (dy/dt) / (dx/dt) = (6t) / (-6t²) = -1/t

So, the slope of the curve at the point corresponding to t is -1/t.

Answer:

The formula for average cost (AC) is:

AC = (Total cost / Quantity)

To find the total cost, we need to add the variable cost (VC) and the avoidable fixed cost:

Total cost = VC + Fixed cost

Total cost = 20Q + 50,000

Now we can substitute this into the formula for average cost:

AC = (Total cost / Quantity)

AC = (20Q + 50,000) / Q

Simplifying this expression gives:

AC = 50,000/Q + 20

Therefore, the firm's average cost function is:

AC = 50,000/Q + 20

So, the correct answer is B.
