Answer:

465 miles

Step-by-step explanation:

From the question,

S₁ = d₁/t₁............................... Equation 1

Where S₁ = Speed travels by Perry for the first journey, d₁= First distance traveled by Perry, t₁ = First time taken.

make d₁ the subject of the equation

d₁ = S₁t₁................... Equation 2

Given; S₁ = 55 miles per hour, t₁ = 5.5 hour

Substitute these values into equation 2

d₁ = 55×5.5

d₁ = 302.5 miles.

Also,

d₂ = s₂t₂.......................... Equation 2

Given: s₂ = 65 miles per hour, t₂ = 2.5 hours.

d₂ = 65×2.5

d₂ = 162.5 miles

Hence,

Total distance = d₁+d₂

Total distance = 302.5+162.5

Total disstance = 465 miles

Answer:

The market is 10 m from the girl's house.

Step-by-step explanation:

If a girl walked 8 m from her house to market and she covered 4/5 of the distance the market, then 8 m equals 4/5ths of the total distance from her house to the market.

Let x be the total distance from the girl's house to the market.

Create an equation with the given information and defined variable:

\(\implies \dfrac{4}{5}x=8\)

Multiply both sides of the equation by 5:

\(\implies 5 \cdot \dfrac{4}{5}x=5 \cdot 8\)

\(\implies 4x=40\)

Divide both sides of the equation by 4:

\(\implies \dfrac{4x}{4}=\dfrac{40}{4}\)

\(\implies x=10\)

Therefore, the market is 10 m from the girl's house.

The number of minutes needed to solve an exercise set of variation problems varies directly with the number of problems and inversely with the number of people working on the solutions.  it will take 6 people approximately 24 minutes to solve 42 problems based on the given variation relationship.

Let's denote the number of minutes needed to solve the exercise set as "m," the number of problems as "p," and the number of people as "n." According to the given information, we have the following relationships: m ∝ p (direct variation) and m ∝ 1/n (inverse variation).

We can express these relationships using proportionality constants. Let's denote the constant of direct variation as k₁ and the constant of inverse variation as k₂. Then we have the equations m = k₁p and m = k₂/n.

In the initial scenario, with 4 people solving 18 problems in 36 minutes, we can substitute the values into the equations to find the values of k₁ and k₂. From m = k₁p, we have 36 = k₁ * 18, which gives us k₁ = 2. From m = k₂/n, we have 36 = k₂/4, which gives us k₂ = 144.

Now, we can use these values to determine how many minutes it will take 6 people to solve 42 problems. Substituting n = 6 and p = 42 into the equation m = k₂/n, we get m = 144/6 = 24. Therefore, it will take 6 people approximately 24 minutes to solve 42 problems based on the given variation relationship.

Cindy should hire the 12th worker as it would result in a net increase in profit, with additional revenue exceeding the cost of hiring. Insufficient information is provided to determine the demand curve for labor or compare its elasticity. Events that would shift the factory's demand for capital include new, more efficient machines and rising wages due to a labor shortage.

a. To determine whether Cindy should hire a 12th worker, we need to compare the additional revenue generated with the additional cost incurred. Hiring the 12th worker would increase total revenue by $150 ($2,750 - $2,600) per day, but it would also increase costs by $100. Therefore, the net increase in total profit would be $50 ($150 - $100). Since the net increase in profit is positive, Cindy should hire the 12th worker.

b. By hiring the 12th worker, Cindy can increase her total revenue from $2,600 per day to $2,750 per day. The additional revenue generated by the 12th worker exceeds the cost of hiring that worker, resulting in a net increase in profit.

c. To determine the firm's demand curve for labor, we need information about the marginal product of labor (MPL) and the wage rates. Unfortunately, this information is not provided, so we cannot complete the labor demand table or derive the demand curve for labor.

Without specific data or information about changes in the quantity of labor demanded and wage rates, we cannot determine which demand curve (from part b or c) is more elastic. The elasticity of the demand curve depends on the responsiveness of the quantity of labor demanded to changes in the wage rate.

The events that would shift the factory's demand for capital are:

a. New shoemaking machines being twice as efficient as older machines would increase the productivity of capital. This would lead to an increase in the demand for capital as the factory would require more capital to produce the same quantity of shoes.

b. The wages that the factory has to pay its workers rising due to an economy-wide labor shortage would increase the cost of labor relative to capital. This would make capital relatively more attractive and lead to an increase in the demand for capital as the factory may substitute capital for labor to maintain production efficiency.

The event "Many consumers decide to walk barefoot all the time" would not directly impact the demand for capital as it is related to changes in consumer behavior rather than the production process of the shoemaking factory.

Step-by-step explanation:

The probability of at least one patient having a seizure in the sample is approximately 0.3226 or 32.26%.

The probability of at least one patient having a seizure in a sample of 40 patients with meningitis can be calculated using the complement rule.

The probability of no patients having a seizure can be found by subtracting the probability of at least one patient having a seizure from 1. Since the risk of seizure for any individual patient is 2%, the probability of no patients having a seizure is equal to (1 - 0.02) raised to the power of 40.

Let's calculate this step by step:

P(at least one patient having a seizure) = 1 - P(no patients having a seizure)

P(no patients having a seizure) = (1 - 0.02)^40

P(no patients having a seizure) = 0.98^40

P(no patients having a seizure) ≈ 0.6774

P(at least one patient having a seizure) ≈ 1 - 0.6774 ≈ 0.3226

The critical value Za /2 that corresponds to 98% confidence level is (d) 2.33

Step-by-step explanation:

To obtain the critical value Za/2 that corresponds to a 98% confidence level, we need to determine the value that leaves 2% (0.02) in the tails of the distribution.

Since the confidence level is two-tailed, we need to divide the significance level by 2 to find the area in each tail. In this case, we have 2% divided by 2, resulting in 1% (0.01) in each tail.

Looking up the critical value in a standard normal distribution table or using statistical software, we obtain that the closest value to 0.01 in the table is approximately 2.33.

Therefore, the correct answer is D. 2.33.

The evolution of the function call (things '(11 -2 31)) is as follows:

(things '(11 -2 31)) -> (things '(-2 31)) -> (things '(31)) -> (things '()) -> '() the final result of the given call is '().

The given function is a recursive function called "things" that takes a list as input. It checks if the list is empty (null), and if so, it returns an empty list. Otherwise, it checks if the first element of the list (car x) is greater than 10. If it is, it adds 1 to the first element and recursively calls the "things" function on the rest of the list (cdr x). If the first element is not greater than 10, it subtracts 1 from the first element and recursively calls the "things" function on the rest of the list. The function then returns the result.

Now, let's see the evolution resulting from the call (things '(11 -2 31)):

1. (things '(11 -2 31))

  Since the list is not empty, we move to the next if statement.

  The first element (car x) is 11, which is greater than 10, so we add 1 to it and recursively call the "things" function on the rest of the list.

  The recursive call is (things '(-2 31)).

2. (things '(-2 31))

  Again, the list is not empty.

  The first element (car x) is -2, which is not greater than 10, so we subtract 1 from it and recursively call the "things" function on the rest of the list.

  The recursive call is (things '(31)).

3. (things '(31))

  The list is still not empty.

  The first element (car x) is 31, which is greater than 10, so we add 1 to it and recursively call the "things" function on the rest of the list.

  The recursive call is (things '()).

4. (things '())

  The list is now empty, so the function returns an empty list.

The given statement "In the method of proof, the rules are not used jointly but are applied one at a time and once per line" is True.

In a proof, each step must be justified by a logical rule or principle. These rules are not applied all at once, but rather one at a time and in a specific order. This allows for a clear and organized progression of the proof, and ensures that each step is based on a sound and valid reasoning.

For example, in a proof by contradiction, we assume the opposite of what we want to prove and then show that this assumption leads to a contradiction. In each step of the proof, we apply a logical rule or principle, such as the law of non-contradiction or the transitive property of equality.

By applying the rules one at a time and once per line, we can carefully follow the logical reasoning and ensure that the proof is valid. If we were to apply multiple rules at once or skip steps, the proof could become muddled and the validity of the argument could be called into question. Therefore, it is important to use the rules of logic in a methodical and systematic way when constructing a proof.

The probability of having 63 or more successes in the sample is approximately 0.0266, or 2.66%.

To use the normal approximation to find the probability P(X ≥ 63) for a sample size of n = 90 and population proportion of successes p = 0.6, follow these steps:

Step 1: Calculate the mean (μ) and standard deviation (σ) for the binomial distribution.
\(μ = n * p\) = 90 * 0.6 = 54
\(σ = \sqrt{(n * p * (1 - p))} = \sqrt{(90 * 0.6 * 0.4) }\)= √21.6 ≈ 4.65

Step 2: Use the normal approximation.
To find P(X ≥ 63), first convert X to a z-score:
z = \((X - μ) / σ\) = (63 - 54) / 4.65 ≈ 1.93

Step 3: Find the probability using a z-table or calculator.
Using a z-table or calculator, find the probability of a z-score less than 1.93 (since we want P(X ≥ 63), we need to find the area to the right of the z-score):
P(Z ≤ 1.93) ≈ 0.9734

Step 4: Calculate the complement probability.
Since we want P(X ≥ 63), we need to find the complement probability (1 - P(Z ≤ 1.93)):
P(X ≥ 63) = 1 - 0.9734 = 0.0266

So, the probability of having 63 or more successes in the sample is approximately 0.0266, or 2.66%.
