Step-by-step explanation:

On average, customers needing routine repairs wait for 1.67 hours, while customers needing major repairs wait for 2.5 hours before being served.

Let's consider the average number of customers waiting and the throughput rates for routine repairs and major repairs. With one hoist dedicated to routine repairs and one hoist dedicated to major repairs, the throughput rate for routine repairs is 3 cars per hour, and the throughput rate for major repairs is 1 car per hour. The average number of customers waiting for routine repairs is 5, and the average number of customers waiting for major repairs is 3. Using Little's Law, which states that the average number of customers in a system is equal to the arrival rate multiplied by the average time spent in the system, we can calculate the average waiting time for each type of customer. For routine repairs, the arrival rate is 3 cars per hour, and the average number of customers waiting is 5. Therefore, the average waiting time for routine repairs is 5/3 = 1.67 hours. Similarly, for major repairs, the arrival rate is 1 car per hour, and the average number of customers waiting is 3. Therefore, the average waiting time for major repairs is 3/1 = 3 hours. By dedicating one hoist to routine repairs and one hoist to major repairs, the average waiting time for routine repairs is reduced compared to the previous scenario when all repairs were done on a first-come, first-served basis. However, the waiting time for major repairs has increased due to the lower throughput rate for major repairs compared to routine repairs.

To graph the equation y = (1/2)x, we can plot points on a coordinate plane and connect them to create a straight line. Here's how to do it:

1. Choose some x-values to evaluate the equation. Let's select a range of x-values, such as -10, -5, 0, 5, and 10.

2. Substitute each x-value into the equation to find the corresponding y-values. For example:

  - For x = -10, y = (1/2)(-10) = -5

  - For x = -5, y = (1/2)(-5) = -2.5

  - For x = 0, y = (1/2)(0) = 0

  - For x = 5, y = (1/2)(5) = 2.5

  - For x = 10, y = (1/2)(10) = 5

3. Plot the points (x, y) on a graph. In this case, the points would be:

  (-10, -5), (-5, -2.5), (0, 0), (5, 2.5), (10, 5)

4. Connect the plotted points with a straight line. The line should pass through all the points.

The resulting graph is a straight line with a slope of 1/2, passing through the origin (0, 0), and extending infinitely in both directions.

Here is a rough sketch of the graph:

The probability that the gambler has strictly more than $32 after playing the game five times is 68.75%.

Probability is a branch of mathematics that deals with the likelihood of an event occurring. In this problem, we are dealing with a gambler who is playing a game with equal probability of doubling or reducing their stake to half.

The gambler's initial stake is $32. Let us consider the possible outcomes after one play of the game. The stake can either double to $64 or reduce to $16, each with equal probability. If the stake doubles, the gambler has more than their initial stake. If the stake is reduced to half, the gambler has less than their initial stake.

Now, let us consider the possible outcomes after two plays of the game. There are four possible outcomes:

(1) the stake doubles twice and the gambler has

=> $64 * 2 = $128,

(2) the stake doubles then reduces to half and the gambler has

=> $32 * 2 * 0.5 = $32,

(3) the stake reduces to half then doubles and the gambler has

=> $32 * 0.5 * 2 = $32,

(4) the stake reduces to half twice and the gambler has

=> $32 * 0.5 * 0.5 = $8.

We can represent these outcomes using a tree diagram. Each branch represents a possible outcome, and the probability of that outcome is written next to the branch.

After five plays of the game, there are 32 possible outcomes.

We can calculate the probability of the gambler having more than their initial stake by adding up the probabilities of all the outcomes where the gambler has more than $32. This turns out to be 0.6875 or 68.75%.

Answer:

y = \(\frac{1}{3}\) x

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = \(\frac{1}{3}\) , then

y = \(\frac{1}{3}\) x + c ← is the partial equation

to find c substitute (- 9, - 3) , that is x = - 9, y = - 3 into the partial equation

- 3 = \(\frac{1}{3}\) (- 9) + c = - 3 + c ( add 3 to both sides )

0 = c

y = \(\frac{1}{3}\) x + 0 , that is

y = \(\frac{1}{3}\) x

Percent: 83%

You can't really simplify a decimal that has already been simplified.

Step-by-step explanation:

The system of equations is y = -x^2/4 and y = 2x + 1. To solve this system, we can substitute the expression for y from the second equation into the first equation and solve for x. Then, we can substitute the value of x back into either equation to find the corresponding y-value.

Given the system of equations:

y = -x^2/4

y = 2x + 1

We can substitute the expression for y from the second equation into the first equation:

-x^2/4 = 2x + 1

To solve this quadratic equation, we can multiply both sides by 4 to eliminate the fraction:

-x^2 = 8x + 4

Next, we can rearrange the equation to bring all terms to one side:

x^2 + 8x + 4 = 0

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Once we find the solutions for x, we can substitute them back into either equation to find the corresponding y-values.

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

Mr. Harbin would consume 3 3/4 gallons of gas during a five-day work week based on his daily gas usage of 3/4 gallon. The correct option is

3 3/4.

To calculate how much gas Mr. Harbin would use in a five-day work week, we need to calculate the total gas consumption for each day and then add them together.

Since Mr. Harbin uses 3/4 of a gallon of gas each day, the total gas consumption for one day is 3/4 gallon.

For the gas consumption for five days, we multiply the daily consumption by the number of days:

(3/4 gallon/day) * 5 days = 15/4 gallons

To simplify the fraction, we can convert 15/4 to a mixed number:

15/4 = 3 3/4

Therefore, Mr. Harbin would use 3 3/4 gallons of gas in a five-day work week.

In summary, the answer is 3 3/4. Mr. Harbin would consume 3 3/4 gallons of gas during a five-day work week based on his daily gas usage of 3/4 gallon.

The income you need to afford a $425,000 house is largely dependent on your debt-to-income ratio, credit score, and down payment. However, a general rule of thumb is to have an annual income that is at least three times the purchase price of the home, which in this case would be $1,275,000.

To more accurately determine the income needed to afford a $425,000 house, consider factors such as the interest rate on the mortgage, property taxes, homeowners insurance, and any homeowner association fees.

These additional expenses can significantly impact your monthly mortgage payment and thus your income requirements.
It's important to keep in mind that lenders have varying criteria when determining mortgage eligibility and income requirements, so it's best to speak with a mortgage professional to get a more accurate estimate based on your individual circumstances.
