The volume of oil exiting the pipe is approximately 100 cu in/hr, 2,400 cu in/day, and 1.39 cu ft/day when converting cu in/day to cubic feet per day.



To calculate the volume of oil exiting the pipe every hour, you would need to know the flow rate of the oil in cubic inches per hour. Let's assume the flow rate is 100 cubic inches per hour.To find the volume of oil exiting the pipe every day, you would multiply the flow rate by the number of hours in a day. There are 24 hours in a day, so the volume of oil exiting the pipe every day would be 100 cubic inches per hour multiplied by 24 hours, which equals 2,400 cubic inches per day.

To convert the volume from cubic inches per day to cubic feet per day, you would need to divide the volume in cubic inches by the number of cubic inches in a cubic foot. There are 1,728 cubic inches in a cubic foot. So, dividing 2,400 cubic inches per day by 1,728 cubic inches per cubic foot, we get approximately 1.39 cubic feet per day.

Therefore, the volume of oil exiting the pipe is approximately 100 cubic inches per hour, 2,400 cubic inches per day, and 1.39 cubic feet per day.

Pythagorean theorem tells us how the side lengths of right triangles are related.

The Pythagorean theorem, also known as the Pythagorean identity, states that the sum of the squares of the lengths of the two sides forming the right angle is equal to the square of the length of the hypotenuse in any right triangle (the side opposite the right angle). In other words, the Pythagorean theorem can be used to calculate the length of the hypotenuse given the lengths of the two sides of a right triangle.

This relationship can be written as the equation:

\(a^2 + b^2 = c^2\)

where a and b are the lengths of the legs, and c is the length of the hypotenuse. The Pythagorean Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery.

Answer:

if Kira drives at the same rate, she would drive 567 miles in 9 hours.

Step-by-step explanation:

To determine how many miles Kira would drive in 9 hours at the same rate, we need to first calculate her average speed in miles per hour. To do this, we divide the total number of miles she drove (441 miles) by the number of hours she drove (7 hours):

441 miles / 7 hours = 63 miles/hour

Once we know her average speed, we can use it to calculate the number of miles she would drive in 9 hours. To do this, we multiply her average speed (63 miles/hour) by the number of hours she would drive (9 hours):

63 miles/hour * 9 hours = <<63*9=567>>567 miles

The man can wear 15 different outfit combinations by mixing and matching his six different sport shirts and four different pairs of slacks.

Combination is a way of counting the number of different groups of items that can be selected from a larger set without regard to the order in which they are selected.

In this case, the man has six different sport shirts and four different pairs of slacks, and he wants to know how many different outfit combinations he can wear. We can use the formula for combinations to calculate the number of possibilities.

The formula for combinations is:

ⁿCₓ = n! / (x! * (n - x)!)

Where n is the total number of items, x is the number of items being selected, and the exclamation mark (!) represents the factorial of a number (i.e., the product of all positive integers up to that number).

Using this formula, we can calculate the number of different combinations the man can wear as follows:

Number of sport shirts (n) = 6

Number of slacks (x) = 4

Number of combinations = ⁶C₄ = 6! / (4! * (6 - 4)!)

= (6 * 5 * 4 * 3 * 2 * 1) / [(4 * 3 * 2 * 1) * (2 * 1)]

Answer:

67.5$

Step-by-step explanation:

75$ x .10 = 7.5$

75$ - 7.5$ = 67.5$

Answer:

$67.50

Step-by-step explanation:

First, find the discount.

Multiply the discount rate by the cost.

discount rate * cost

The discount rate is 10% and the cost is $75.

$75 * 10%

Convert 10% to a decimal. Divide 10 by 100 or move the decimal place two spots to the left.

10/100 = 0.10       or         10.0 --> 1.0 --> 0.10

$75 * 0.10

$7.5

Now, find the final price.

Since it is a 10% discount, we must subtract the discount amount from the cost.

cost - discount

The cost is $75 and the discount is $7.5

$75 - $7.5

$67.50

The final price of a item that costs $75 with a 10% discount is $67.50

Answer:

There are 4 white marbles,6 red marbles, and 2 blue marbles. Once a marble is selected,it is not replaced.Find the probability of selecting 2 blue marbles. --- # of ways to succeed: 2C2 = 1 --- # of random pairs: 12C2 = 66 --- P (2 blue) = 1/66

Answer:

\(\dfrac{1}{66} \approx 1.5\%\)

Step-by-step explanation:

Probability is a measure of the likelihood or chance that a specific event or outcome will occur.

\(\boxed{\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}}\)

We are told that there are 4 white marbles, 6 red marbles and 2 blue marbles. Therefore, the probability of selecting a blue marble on the first pick is:

\(\sf P(blue\;1st)=\dfrac{2}{4+6+2}=\dfrac{2}{12}=\dfrac{1}{6}\)

As the first marble selected is not replaced, we now have 1 blue marble remaining, and a total of 11 marbles remaining.

Therefore, the probability of selecting a blue marble on the second pick is:

\(\sf P(blue\;2nd)=\dfrac{1}{11}\)

To calculate the probability of both events occurring (selecting 2 blue marbles), we multiply the probabilities:

\(\sf P(blue\;1st)\;and\;P(blue\;2nd)=\dfrac{1}{6} \times \dfrac{1}{11}=\dfrac{1}{66}\)

Therefore, the probability of selecting 2 blue marbles without replacement is 1/66 ≈ 1.5%.

There is enough proof to indicate that the percentage of newsletter readers who possess a Rolls Royce is less than 69%.

The null hypothesis is that p = 0.69, meaning that 69% of the newsletter readers own a Rolls Royce. The alternative hypothesis is that p < 0.69, meaning that less than 69% of the newsletter readers own a Rolls Royce.

We can use a one-tailed z-test to test the hypothesis. Assuming a sample size of n = 100, if we observe fewer than 69 Rolls Royces in our sample, we can reject the null hypothesis.

Using a z-test, we can calculate the z-score by using the formula:

z = (p' - p) / sqrt(p * (1 - p) / n)

where p' is the sample proportion, p is the hypothesized proportion, and n is the sample size.

At a significance level of 0.10, the critical z-value is -1.28. If the calculated z-score is less than -1.28, we can reject the null hypothesis.

If we conduct a survey of 100 newsletter readers and find that 58 of them own a Rolls Royce, the sample proportion would be p' = 0.58. Calculating the z-score, we get:

z = (0.58 - 0.69) / sqrt(0.69 * 0.31 / 100) = -1.83

Since -1.83 is less than -1.28, we can reject the null hypothesis and conclude that there is sufficient evidence to suggest that fewer than 69% of the newsletter readers own a Rolls Royce.

The probability of having every bin filled with at least one ball if n balls are distributed randomly into m bins is given by the formula 1 - (m-1/m)^n.

Let's break it down step-by-step:

Step 1: Probability of a ball being put into a specific Bin Since there are m bins, the probability of a ball being put into a specific bin is 1/m. Therefore, the probability of a ball not being put into that bin is (m-1)/m.

Step 2: Probability of a ball not being put into a specific Bin Since there are m bins, the probability of a ball not being put into a specific bin is (m-1)/m. Therefore, the probability of a ball being put into that bin is 1/m.

Step 3: Probability of every bin being filled with at least one ball Using the above two probabilities, the probability of a specific bin not being filled with a ball is (m-1)/m. Therefore, the probability of all m bins not being filled with a ball is (m-1/m)^n. Finally, the probability of every bin being filled with at least one ball is 1 - (m-1/m)^n.

Therefore, the probability of having every bin filled with at least one ball if n balls are distributed randomly in to m bins is given by the formula 1 - (m-1/m)^n.

The given statement, "The formula Q logically implies PV" is true, because  in propositional logic, the formula Q logically implies PV Q due to the principle of explosion or ex falso quodlibet, where any conclusion can be derived from a false premise.

The formula Q logically implies PV Q is a valid implication in propositional logic. This is known as the principle of explosion or ex falso quodlibet. According to this principle, if we assume a false proposition (Q) to be true, then any other proposition (PV Q) can also be considered true. In other words, if we have a false premise, any conclusion can be logically derived from it. This is a fundamental principle in logic and is often used in proofs by contradiction.

To understand why this is true, let's consider the truth table for the logical operator PV (OR). If Q is false, then PV Q will be true regardless of the truth value of the other proposition. This is because in an OR statement, if one of the propositions is true (even if the other is false), the whole statement is true.

Therefore, the statement "The formula Q logically implies PV Q" is true, as per the principles of propositional logic.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The parameters for this problem are given as follows:

n = 500, p = 0.53.

Hence the mean and the standard error are given as follows:

Hence the probability of less than half is the p-value of Z when X = 0.5, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

Z = (0.5 - 0.53)/0.0223

Z = -1.35
