To determine how much you should expect to pay for gas in Philadelphia versus Cleveland, we need to compare the transportation expenses in both cities. Based on the given data, the transportation expenses are as follows:

Philadelphia: $117

Cleveland: $106

To calculate the expected gas prices, we need to consider the transportation expenses relative to the national average. The formula to find the expected gas price is:

Expected Gas Price = National Average * (Transportation Expense / National Average)

National Average for gas = $2.59

For Philadelphia:

Expected Gas Price in Philadelphia = $2.59 * ($117 / 92) ≈ $3.30

For Cleveland:

Expected Gas Price in Cleveland = $2.59 * ($106 / 78) ≈ $3.51

Comparing the expected gas prices, we find that:

A. $3.03 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

B. $1.95 / $2.59: This option does not match the expected gas prices in Philadelphia and Cleveland.

C. $2.34 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

D. $2.75 / $3.24: This option matches the expected gas prices in Philadelphia and Cleveland.

Therefore, the correct answer is:

D. $2.75 / $3.24

Answer:

The system of equations is:

• C(x)=2400+60x

• R(x)=120x

The number of bicycles to break even = 40

Explanation:

Let the number of bikes sold = x

• The operating cost of the store per month = $2400

• Cost Price Per bike = $60

Thus, the total monthly cost for the store:

Next, the average selling price of each bicycle is $120, therefore, the monthly revenue of the store:

The store breaks even when the cost equals its revenue.

We then solve for x:

The store must sell 40 bicycles in order to break even.

Answer:

\(36\)

Step-by-step explanation:

The expression \(_nC_k\) is used to denote the number of ways you can choose \(k\) things from a set of \(n\) things. It is equal to:

\(_nC_k=\binom{n}{k}=\frac{n!}{k!(n-k)!}\)

In this case, \(n=9\) and \(k=2\), so:

\(\implies \frac{9!}{2!(9-2)!}=\frac{9!}{2!7!}=\boxed{36}\)

You can also think of it like this:

\(_9C_2\) is saying 9 choose 2. We are choosing 2 things from a set of 9 things, where order doesn't matter. For the first thing we choose, there are 9 options. Then 8 options, 7, and so on. Since we're only choosing two things, there are \(9\cdot 8=72\) permutations. However, the order of which we choose each thing does not affect what we've chosen overall (e.g. If we're choosing two donut flavors original and strawberry, it doesn't matter which flavor I choose first, because I'm still getting the same two flavors). Therefore, we must divide this by the number of ways we can arrange two distinct values, which is \(2!\). Our answer is thus \(\frac{72}{2!}=\frac{72}{2}=\boxed{36}\)

=========================================================

Explanation:

We have 9*8 = 72 different permutations. This is if we used the nPr formula with n = 9 and r = 2.

Notice the countdown from 9 to 8. This is because we don't reuse the same element twice.

Since order doesn't matter with nCr, we will divide by 2. This is because something like AB is the same as BA. So we go from 72 to 72/2 = 36

The value 36 is found in Pascal's Triangle in the row that has 1,9,... at the start of it. Start at the left hand side and count exactly 3 spaces to the right, and you should land on 36.

y = -27.6

Step-by-step explanation:

To solve for y, you need to isolate the variable on one side of the equation. \(5(y+25)=-13\) ⇒ \(y + 25 = -2.6\) ⇒ \(y = -27.6\).

Answer:

-27.6

Step-by-step explanation:

\(5(y + 25) = -13\)

First, distribute the problem.

\(5y + 125 = -13\)

Secondly, subtract 125 from -13 and 125.

\(125 - 125 = 0\)

\(-13 - 125 = -138\)

Now, we are left with 5y = -138.

Lastly, we divide -138 by 5.

\(-138 / 5 = -27.6\)

Therefore, y is -27.6.

Thus, total products in hours

= 50 products × 75 hours each

= 3750 product hours

Also said that, 4 breakdowns in 3750 product hours,

so, (4/3750) = 1.067 × 10⁻³ = 0.001067 breakdowns per hour.

Also, an average of 0.001067 breakdowns per hour = λ

Answer:

Yes

Step-by-step explanation:

I think the test

The given function is C(x) = 936 + 80x + 0.12x^2, where x represents the number of mountain bikes produced daily. The average cost function is also given by C(x).
To make the mountain bike as affordable as possible, the company should target a production level of 333.33 mountain bikes daily, where the average cost function is at its minimum. Rounded to 2 decimal places, the answer is

c = 333.33.

First, let's correct the given cost function: C(x) = 936x + 80x^2 + 0.12x^3. Now, we'll use the terms "function," "average," and "increases."

To find the average cost function, we need to divide the total cost function, C(x), by the number of mountain bikes produced daily, x. Let A(x) represent the average cost function:

A(x) = C(x) / x

Now, let's substitute C(x) into this equation:

A(x) = (936x + 80x^2 + 0.12x^3) / x

Simplify by canceling out an x term:

A(x) = 936 + 80x + 0.12x^2

To find the production level c where the average cost function decreases and then increases, we need to find the minimum point on the A(x) curve. To do this, we'll differentiate A(x) with respect to x to obtain the first derivative:

A'(x) = 80 + 0.24x

Now, set the first derivative equal to zero and solve for x:

80 + 0.24x = 0

0.24x = -80

x = c = -80 / 0.24

Round to 2 decimal places:

c ≈ 333.33

So, to make the mountain bike as affordable as possible, the company should target a production level of approximately 333.33 mountain bikes daily.

(a) The slope of an indifference curve at an arbitrary consumption bundle (x0, y0) is given by the negative ratio of the marginal utilities of x and y, i.e., -MUx/MUy.

(b) Taking the derivative of the expression in part (a) gives the second-order derivative of the indifference curve. If the utility function u is quasiconcave on R+2, this second-order derivative will be positive, demonstrating the law of diminishing marginal rate of substitution.

In economics, an indifference curve represents the combinations of two goods (x and y) that provide the same level of utility or satisfaction to an individual.

The slope of an indifference curve measures the rate at which the individual is willing to substitute one good for another while remaining indifferent.

To derive an expression for the slope of an indifference curve at a given consumption bundle (x0, y0), we consider the marginal utilities of x (MUx) and y (MUy).

The slope is determined by the negative ratio of MUx to MUy, which indicates the relative change in x compared to y that maintains the same level of utility.

Taking the derivative of this expression provides the second-order derivative of the indifference curve. If the utility function u is quasiconcave on R+2, which means that indifference curves are convex, the second-order derivative will be positive.

This confirms the law of diminishing marginal rate of substitution, stating that as an individual consumes more of one good, they are willing to give up less of the other good to maintain the same level of satisfaction.

Step-by-step explanation:

1. The expected number is 2/3. (2) The probability is 4/7. (3) The expected amount of money (in PLN) the players will spend on the game can be calculated as 7 PLN.

1. To find the expected number of obtained black balls, we can consider the probability of drawing a black ball on each round until a green ball is drawn. Since there are 2 black balls out of a total of 7 balls, the probability of drawing a black ball in each round is 2/7. Since the draws are made with replacement and independently, the expected number of obtained black balls is equal to the probability of drawing a black ball on each round, which is 2/7.

2. The probability that Adam will win the reward in the shooting game can be calculated using a geometric distribution. The probability that Adam wins on the first round is the probability that he hits, which is 1/4. The probability that Bob wins on the first round is the probability that Adam misses (3/4) multiplied by the probability that Bob hits (1/3). In subsequent rounds, the probabilities adjust accordingly. By summing the probabilities of Adam winning on each round, we find that the probability of Adam winning the reward is 4/7.

3. To calculate the expected amount of money spent on the game, we can multiply the probability of each round by the cost of each round (1 PLN) and sum them up. Since the game ends when one of the players wins, the number of rounds played follows a geometric distribution. The expected amount of money spent can be calculated by multiplying the probability of each round by the cost of each round and summing them up. In this case, since the game ends when one of the players hits, the expected amount of money spent is 7 PLN.

Answer:

a. 3:4

b) 63 players

Step-by-step explanation:

From the question, we know that: Three out of seven soccer players wore headbands in a soccer league.

This means Number of soccer players who did not wear head bands = 7 - 3

= 4

a. Write the ratio of soccer players who wore headbands to soccer players who did not.

Soccer player who wore headbands : Soccer players who did not

= 3:4

b. If there were 36 players in the league who did not wear headbands, how many players were in the league?

Soccer player who wore headbands : Soccer players who did not

= 3:4

36 players in the league who did not wear headbands

Hence, number of players in the league who wore head bands is calculated as:

3/4 = x/36

Cross Multiply

4x = 3 × 36

x = 3 × 36/4

x = 27

The total number of players in the league

= 27 + 36

= 63 players
