The lines are parallel because they have the same slope in the equation of lines

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first equation be 9y - 6x = -18   be equation (1)

Let the second equation be 3y - 2x = 24   be equation (2)

On simplifying the equation , we get

Adding 6x on both sides of the equation , we get

9y = 6x - 18

Divide by 9 on both sides of the equation , we get

y = ( 2/3 )x - 2

So , the slope of line 1 is m = 2/3

And , for the second equation ,

Adding 6x on both sides of the equation , we get

3y = 2x + 24

Divide by 3 on both sides of the equation , we get

y = ( 2/3 )x + 8

So , the slope of line 2 is m = 2/3

Since the slopes of the lines are same , they are parallel lines

Hence , the equation of lines are solved

Answer:

To find y'(3), we need to use implicit differentiation to differentiate both sides of the equation with respect to x and then solve for y'.

Differentiating both sides with respect to x, we get:

(2x/25) + (2y/64) * (dy/dx) = 0

Now we can solve for dy/dx:

(2y/64) * (dy/dx) = -(2x/25)

dy/dx = -(2x/25) / (2y/64)

dy/dx = -32x/25y

To find y'(3), we need to substitute x=3 and y=6.4 into the expression for dy/dx:

y'(3) = -32(3)/(25)(6.4)

y'(3) = -0.3

Therefore, the value of y'(3) is -0.3

The value of y'(3) in (2x/25) + (2y/64) = 1, is  - 0.3

Finding the derivative of an implicit function is the process of implicit differentiation.

In other words, this method is utilized to discover the implicit derivative.

To find y'(3), After differentiating both sides of the equation with respect to x using implicit differentiation, we must next solve for y'.

Differentiating both sides with respect to x we get,

(2x/25) + (2y/64)×(dy/dx) = 0

Solving for dy/dx

(2y/64)×(dy/dx) = -(2x/25)

dy/dx = -(2x/25) / (2y/64)

dy/dx = -32x/25y

To find y'(3), Replacing x=3 and y=6.4 into the expression for dy/dx:

y'(3) = -32(3)/(25)(6.4)

y'(3) = -0.3

Therefore, the value of y'(3) is - 0.3

Six friends group is playing poker one night. They have a standard 52-card deck. So, here, total number of possible outcomes of game = 52

Now, the designated cards are , Queen of Clubs, 10 of Hearts. So,

a) Number of cards are in the deck that are not one of the designated cards

= 52 - 2 = 50

Number of cards that need to be dealt in order for each player to have 7 cards

= 5× 7 = 35

Thus total possible number of ways

= ⁵⁰C₃₅ = 2250829575120, which are ways to deal the cards without getting one of the designated cards.

b) Number of cards are in the deck = 52

Number of cards that need to be dealt in order for each player to have 7 cards = 5× 7 = 35

Thus total possible number of ways

The HHI is less than 1,800, which is considered a low level of market concentration. Therefore, we can conclude that both scenarios represent relatively competitive markets.

The Herfindahl-Hirschman Index (HHI) is a measure of market concentration that is commonly used to assess the degree of competition in a market. The index is calculated as the sum of the squared market shares of all the firms in the market. The HHI can range from 0 to 10,000, with higher values indicating greater market concentration.

To calculate the HHI for the two scenarios given, we need to first calculate the market shares of the teams in each scenario. In the first scenario, there are four teams with the following market shares:

Team A: 8/10 = 0.8

Team B: 2/10 = 0.2

Teams C and D: 0/10 = 0

The HHI for this scenario is calculated as:

HHI = [tex](0.8^2 + 0.2^2 + 0^2 + 0^2) \times10,000[/tex]

= 68,000

In the second scenario, there are eight teams with the following market shares:

Teams A and B: 4/10 = 0.4 each

Teams C and D: 1/10 = 0.1 each

Teams E, F, G, and H: 0/10 = 0 each

The HHI for this scenario is calculated as:

HHI = [tex](0.4^2 + 0.4^2 + 0.1^2 + 0.1^2 + 0^2 + 0^2 + 0^2 + 0^2) \times 10,000[/tex]

= 16,000

In both scenarios, the HHI is less than 1,800, which is considered a low level of market concentration. Therefore, we can conclude that both scenarios represent relatively competitive markets.

c. P(10.88 ≤ x ≤ 15.3) is 61.38%

d. P(4.72 ≤ x ≤ 12.46) is 99.45%

Probability is the measure of the likelihood of an event occurring. It is a way of quantifying uncertainty and predicting the likelihood of an outcome. In this question, we will use the normal distribution to calculate probabilities.

The mean is the center of the distribution, and the standard deviation measures the spread of the distribution.

a. P(x ≥ 12.5):

Using a standard normal distribution table, we find that the area to the right of 12.5 is 0.0668. This means that the probability of x being greater than or equal to 12.5 is 0.0668 or 6.68%.

b. P(x ≤ 9):

Using a standard normal distribution table, we find that the area to the left of 9 is 0.0228. This means that the probability of x being less than or equal to 9 is 0.0228 or 2.28%.

c. P(10.88 ≤ x ≤ 15.3):

Using a standard normal distribution table, we find that the area to the left of 15.3 is 0.9987 and the area to the left of 10.88 is 0.3849. Therefore, the area between 10.88 and 15.3 is

=> 0.9987 - 0.3849 = 0.6138.

This means that the probability of x being between 10.88 and 15.3 is 0.6138 or 61.38%.

d. P(4.72 ≤ x ≤ 12.46):

Using a standard normal distribution table, we find that the area to the left of 12.46 is 0.9946 and the area to the left of 4.72 is 0.0001. Therefore, the area between 4.72 and 12.46 is

=> 0.9946 - 0.0001 = 0.9945.

A. His monthly mortgage payment is $690.25.

B. He will pay a total of $123,492 in interest over the life of the loan

C. He will make a total of $248,490 in loan payments over the life of the loan.

D. The difference between his monthly loan payment and his monthly rent is $9.75.

Here are the calculations based on the given information:

Loan amount = $125,000

Interest rate = 5.25%

Loan term = 30 years (360 months)

Monthly mortgage payment = $690.25

To calculate the monthly mortgage payment, we can use the following formula:

P = L[c(1 + c)^n]/[(1 + c)^n - 1]

Where:

P = monthly mortgage payment

L = loan amount

c = monthly interest rate (5.25% / 12)

n = loan term in months (30 years x 12 months)

Plugging in the numbers, we get:

P = 125000[(0.0525/12)(1 + 0.0525/12)^360]/[(1 + 0.0525/12)^360 - 1]

P = $690.25

Therefore, Frank's monthly mortgage payment is $690.25.

B. To calculate the total interest he will pay on the loan, we can multiply the monthly mortgage payment by the total number of payments (360) and subtract the loan amount:

Total interest = Pn - L

Total interest = $690.25 x 360 - $125,000

Total interest = $123,492

Therefore, Frank will pay a total of $123,492 in interest over the life of the loan.

C. To calculate the total of all loan payments he will make, we can multiply the monthly mortgage payment by the total number of payments:

Total loan payments = P n

Total loan payments = $690.25 x 360

Total loan payments = $248,490

Therefore, Frank will make a total of $248,490 in loan payments over the life of the loan.

D. To calculate the difference between Frank's monthly loan payment and his monthly rent, we can subtract his monthly rent ($700) from his monthly mortgage payment ($690.25):

Monthly difference = $700 - $690.25

Monthly difference = $9.75

Therefore, the difference between Frank's monthly loan payment and his monthly rent is $9.75.

The value of the evaluated function f(x) = -3x² + 2x  at  

(i) f(-2) is -16   ;

(ii) f(a) is -3a² + 2a .

The Function is represented as : f(x) = -3x² + 2x  ;

(i) We have to evaluate the above function at f(-2),

So, we substitute x = -2 into the function:

we get ;

⇒ f(-2) = -3(-2)² + 2(-2)

⇒ f(-2) = -12 - 4 = -16  .

So ,  f(-2) = -16  .

(ii) Next we have to evaluate f(a),

So , we substitute x = a into the function:

⇒ f(a) = -3a² + 2a

So , f(a) = -3a² + 2a   .
