Step-by-step explanation:

I assume the ? is the left leg of the left triangle.

the middle line (right leg of the smaller left triangle, and the left leg of the larger right triangle) bisects the top angle of the main large triangle (because the top angles left and right from the middle line are equal).

that means per the angle bisector theorem

5 / 4 = 10 / ?

5 = 10×4/? = 40/?

?×5 = 40

? = 40/5 = 8

There are 20,000 different phone numbers possible that is 7-digits long and start with either 824 or 825.

Fundamental Principle of Counting, also called the counting rule, is the method to count how many ways multiple independent events can occur.

Based on the given information, all phone numbers are 7-digits long and starts with either 824 or 825. Hence, the four last digits will be the combination of numbers from 0 to 9.

Thus, by Fundamental Principle of Counting, the number of possible outcomes is 20,000.

= (number of phone numbers starting with 824) + (number of phone numbers starting with 825)

= (10 x 10 x 10 x 10) + (10 x 10 x 10 x 10)

= 20,000

10 divided by 2 1/2 is 4.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. The answer thus derived is the quotient and the left over number is the remainder.

10 divided by 2 1/2 but I can’t figure it out.

It can be written as 10÷2 1/2

convert mixed fraction to improper fraction we get,

\(2\frac{1}{2}= \frac{5}{2}\)

Then divided 10 by 5/2 we get\(\frac{10}{\frac{5}{2} } = 10*\frac{2}{5} = 4\).

Hence, 10 divided by 2 1/2 is 4.

To calculate the incremental cost of financing the marginal 10% with the second loan, we need to compare the total interest paid over the 30-year period for both loans. The difference in total interest paid will represent the incremental cost. Using a mortgage calculator, we calculate the total interest paid over the 30-year period for this loan.

a) For the 80% loan at 3.5%:

Loan amount = 80% of $400,000 = $320,000

Interest rate = 3.5%

Loan term = 30 years

Using a mortgage calculator, we can determine the total interest paid over the 30-year period for this loan.

b) For the 90% loan at 4%:

Loan amount = 90% of $400,000 = $360,000

Interest rate = 4%

Loan term = 30 year

To find the incremental cost of financing the marginal 10%, we subtract the total interest paid for the 80% loan from the total interest paid for the 90% loan. By comparing the two options, we can determine the additional interest cost incurred by financing the additional 10% with the second loan.

There are 6 probability  5 card poker hands with at least 3 Aces that can be dealt from a standard deck of 52 cards.

A standard deck of 52 cards contains 4 Aces, so the maximum number of Aces that can be dealt in a 5 card hand is 3. To determine the number of possible 5 card poker hands with at least 3 Aces, we must first consider the different combinations of 3 Aces in a 5 card hand. There are 6 possible combinations: AAAxx, AAxxA, AxxAA, xAAAX, xAxxA, and xxAAA. This means that there are 6 possible 5 card poker hands with at least 3 Aces that can be dealt from a standard deck of 52 cards. To calculate this, we first counted the number of Aces in the deck and then calculated the number of possible combinations of 3 Aces in a 5 card hand. Finally, we multiplied this number by the number of remaining cards in the deck (48) to get the total number of possible hands.

4 Aces x 6 combinations = 24

24 x 48 remaining cards = 1,152

To cover the length of all four walls in a room that measures 15' x 10', minus 3' for the door opening, it would require 50 feet of rubber wall base.

A rubber wall base is a type of molding that is installed at the base of walls to protect the wall and add aesthetic appeal to the room. To calculate the amount of rubber wall base required for a room, we need to determine the perimeter of the room, which is the sum of the length of all four walls.

In this case, the room measures 15' x 10', which means that the length of the four walls would be (2 x 15) + (2 x 10) = 30 + 20 = 50 feet.

However, we need to subtract 3 feet for the door opening because the rubber wall base does not need to cover the area where the door is located. Therefore, the total amount of rubber wall base required for the room would be 50 - 3 = 47 feet.

But, we need to add some extra footage for corner pieces and cuts. Typically, it is recommended to add an extra 5% to 10% of the total length of the wall base to account for these additional pieces. So, adding 5% of 47 feet, we get an additional 2.35 feet, which we can round up to 3 feet.

Therefore, the final answer is 47 + 3 = 50 feet.

a. On the basis of the utility formula above,  if you were risk-averse with A = 4, you would select either investment 3 or investment 4.

b. If you were risk-neutral, you would select investment 4 with an expected return of 0.24.

c.  The variable (A) in the utility formula represents the investor's aversion to risk. The correct answer is B

To determine the optimal investment based on the utility formula, we need to calculate the utility value for each investment option and compare them.

Investment 1:

Expected Return (E(r)) = 0.12

Standard Deviation (σ) = 0.302

Investment 2:

Expected Return (E(r)) = 0.15

Standard Deviation (σ) = 0.503

Investment 3:

Expected Return (E(r)) = 0.21

Standard Deviation (σ) = 0.164

Investment 4:

Expected Return (E(r)) = 0.24

Standard Deviation (σ) = 0.21

Utility formula: U = E(r) - 1/2Aσ^2

(a) Risk-Averse (A = 4):

To calculate the utility value for each investment:

Investment 1:

U1 = 0.12 - 1/2 * 4 * (0.302)^2

U1 ≈ 0.02

Investment 2:

U2 = 0.15 - 1/2 * 4 * (0.503)^2

U2 ≈ 0.02

Investment 3:

U3 = 0.21 - 1/2 * 4 * (0.164)^2

U3 ≈ 0.20

Investment 4:

U4 = 0.24 - 1/2 * 4 * (0.21)^2

U4 ≈ 0.20

Since investments 3 and 4 have the highest utility values of approximately 0.20, if you were risk-averse with A = 4, you would select either investment 3 or investment 4.

(b) Risk-Neutral (A = 0):

When an investor is risk-neutral (A = 0), the utility formula simplifies to U = E(r). In this case, we only consider the expected return.

Comparing the expected returns of the investments:

Investment 1: 0.12

Investment 2: 0.15

Investment 3: 0.21

Investment 4: 0.24

Based on expected returns alone, if you were risk-neutral, you would select investment 4 with an expected return of 0.24.

The marginal utility per dollar spent on the fifth apple is 60. The correct option is D.

The marginal utility simply refers to the change or extra satisfaction derived from the change in consumption.

Hence, the marginal utility of the fifth apple equals :

Difference /change or extra satisfaction derived by consuming one more than 4 apples = (total utility of 5th apple - total utility of 4th apple)

= (250 - 220) = 30

Hence, marginal utility per dollar: Marginal utility/price per apple

Price per apple = $0.5

Marginal utility of 5th apple = 30

Marginal utility of 5th apple = 30 / 0.5

Marginal utility of 5th apple = 60

Therefore, the marginal utility per dollar spent on the fifth apple is 60. The correct option is D.

The Cauchy stress vector \(t^n\) on the plane passing through point P with a normal vector \(n = 3e_1 + e_2 - 2e_3 \: is \: t^n = [3; 12; 1] \: MPa.\)

The angle between \(t^n\) and the vector normal to the plane is approximately 1.147 radians or 65.72 degrees.

The normal component of \(t^n\) on the plane is approximately 5.08 MPa, and the shear component is [-2.08; 6.92; 1] MPa.

To determine the Cauchy stress vector, denoted as \(t^n\), on the plane passing through point P with a normal vector

\(n = 3e_1 + e_2 - 2e_3\), we can use the formula:

\(t^n = [ \sigma] · n\) where σ is the Cauchy stress tensor and · denotes tensor contraction. Let's calculate \(t^n\)

\([2 5 3; 5 1 4; 3 4 3] · [3; 1; -2] = [23 + 51 + 3*(-2); 53 + 11 + 4*(-2); 33 + 41 + 3*(-2)] = [3; 12; 1]\)

Therefore, the Cauchy stress vector \(t^n\) on the plane passing through point P with a normal vector \(n = 3e_1 + e_2 - 2e_3 \: is \: t^n = [3; 12; 1] \: MPa.\)

To find the length of \(t^n\), we can calculate the magnitude of the stress vector:

\(|t^n| = \sqrt((3^2) + (12^2) + (1^2)) = \sqrt(9 + 144 + 1) = \sqrt(154) ≈ 12.42 \: MPa.\)

The length of \(t^n\) is approximately 12.42 MPa.

To find the angle between \(t^n\) and the vector normal to the plane, we can use the dot product formula:

\(cos( \theta) = (t^n · n) / (|t^n| * |n|)\)

The vector normal to the plane is \(n = 3e_1 + e_2 - 2e_3\)

So its magnitude is \(|n| = \sqrt((3^2) + (1^2) + (-2^2)) = \sqrt (9 + 1 + 4) = \sqrt(14) ≈ 3.74.\)

\(cos( \theta) = ([3; 12; 1] · [3; 1; -2]) / (12.42 * 3.74) = (33 + 121 + 1*(-2)) / (12.42 * 3.74) = (9 + 12 - 2) / (12.42 * 3.74) = 19 / (12.42 * 3.74) ≈ 0.404

\)

\( \theta = acos(0.404) ≈ 1.147 \: radians \: or ≈ 65.72 \: degrees\)

The angle between \(t^n\) and the vector normal to the plane is approximately 1.147 radians or 65.72 degrees.

To find the normal and shear components of t on the plane, we can decompose \(t^n\) into its normal and shear components using the following formulas:

\(t^n_{normal} = (t^n · n) / |n| = ([3; 12; 1] · [3; 1; -2]) / 3.74 ≈ 19 / 3.74 ≈ 5.08 \: MPa \\ t^n_{shear} = t^n - t^n_{normal} = [3; 12; 1] - [5.08; 5.08; 0] = [-2.08; 6.92; 1] \: MPa\)

The normal component of \(t^n\) on the plane is approximately 5.08 MPa, and the shear component is [-2.08; 6.92; 1] MPa.
