E) 10 minutes. At the local fast food joint, cars arrive randomly at a rate of 12 every 30 minutes, which is equivalent to a rate of 0.4 cars per minute (12 arrivals / 30 minutes). The service time for each car averages 2 minutes per arrival and follows an exponential distribution.

To find the average time in the queue for each arrival, we can use Little's Law. Little's Law states that the average number of customers in a system (L) is equal to the arrival rate (λ) multiplied by the average time a customer spends in the system (W). In other words, L = λW.

In this scenario, we are given the arrival rate (λ) and the service time (μ), but we want to find the average time a customer spends in the system (W). To do this, we can use the formula for the average time in an M/M/1 queue: W = 1 / (μ - λ).

Plugging in the values, we get W = 1 / (0.5 cars/minute - 0.4 cars/minute) = 1 / 0.1 cars/minute = 10 minutes. Thus, the average time in the queue for each arrival is 10 minutes.

17. 5^-1 · 5^-1 and 25^-1

8^0 · 8^3 and 8^3

Step-by-step explanation:

When you multiply two same numbers with exponents, just think of it as adding up exponents.

When you divide two same numbers with exponents, just think of it as subtracting exponents.

If a parenthesis has an exponent outside, then every exponent inside the parenthesis will be multiplied by that outside parenthesis.

(5^-1)^-2 · 5^3 ÷ 5^7

5^2 · 5^3 ÷ 5^7

5^5 ÷ 5^7

5^-2

When exponents are negative, you have to flip them or put them on the other side

5^-2 = 1/5^2 = 1/25

Let's try to find the equivalent pairs

6^7 ÷ 6^-2 = 6^5

6^9 = 6^5 Not equivalent

(6^3)^0 = 6

6^0 = 1 (Any number with a zero exponent is always 1)

It is true that the A shift is a type of permutation where elements in a sequence or set are moved to the right or left by a certain number of positions.

For example, shifting the sequence (1,2,3,4,5) to the right by 2 positions would result in the sequence (4,5,1,2,3). This can be represented mathematically as (1,2,3,4,5) → (4,5,1,2,3), which is a permutation of the original sequence. Shifts can be useful in various applications, such as cryptography or data compression, where rearranging elements in a sequence can improve efficiency or security.

True. A shift is a specific type of permutation. In general, a permutation refers to the arrangement of objects in a particular order. A shift, also known as a cyclic permutation, involves moving elements of a set in a fixed direction, such that the order is maintained, but the elements change positions. In a shift, the first element moves to the last position, while all other elements move one position forward. This maintains the relative order of the elements and results in a new arrangement. Therefore, a shift is a type of permutation, as it represents an altered ordering of the elements in a set.

1 pound (lb) weight is equal to 453.59 grams (g).

To convert pounds to grams, you can use this conversion factor.For example, to convert 10 pounds to grams you would multiply 10 by 453.59, which would give you 4535.9 grams.

It's important to note that the pound and gram are both units of measurement for weight or mass. The pound is commonly used in the United States, while the gram is used in the International System of Units (SI). When working with measurements in different units,

it's important to know the correct conversion factors to ensure accuracy. These conversion factors can be memorized or looked up in a conversion table or calculator.

It's also worth noting that for small weight measurements, you can use the kilogram (kg) instead of the gram, since 1 kg = 1000 g.

Answer:

To calculate the interior angles of a triangle, we need to understand some basic principles of geometry.

1. Principle 1: The sum of the interior angles of a triangle is always 180°. This is a fundamental rule in Euclidean geometry, which is the study of flat space. It's based on the definition of a triangle as a three-sided polygon.

2. Principle 2: Each angle in a triangle is measured in degrees (°). Degrees are a unit of measurement for angles, just like meters or feet are units of measurement for distance. There are 360° in a full circle, so an angle that measures 180° is half of a full circle.

Now, let's apply these principles to calculate the third angle in a triangle with angles measuring 30° and 60°.

3. Step 1: Add the two known angles together. If one angle measures 30° and another measures 60°, their sum is 30° + 60° = 90°.

4. Step 2: Subtract the sum from 180° to find the third angle. Since the sum of all three angles must be 180°, we can find the third angle by subtracting the sum of the known angles from 180°. So, 180° - 90° = 90°.

Therefore, the third angle in a triangle with angles measuring 30° and 60° is 90°.

The correct answer is A. 0. As diversification increases, the total variance of a portfolio approaches zero.

As diversification increases, the total variance of a portfolio approaches 0, which means that the portfolio becomes less risky. This occurs because diversification spreads the risk across multiple assets, reducing the impact of any single asset on the portfolio's overall performance. The reduction in risk is due to the fact that some assets in the portfolio may perform well while others may not, but the negative performance of some assets is compensated by the positive performance of others, leading to a lower overall portfolio variance. Therefore, option A is the correct answer.

Diversification is an investment strategy that involves spreading an investor's portfolio across different assets, such as stocks, bonds, real estate, and commodities, with the aim of reducing overall risk.

The ratio of their radius is \(2:3\)

Step-by-step explanation:

Volume of cylinder is \(\pi r^2h\), where r is radius and h is height

We have

The heights of two cylinders are in the ratio of \(5:3\)

\(\frac{h_1}{h_2} =\frac{5}{3}\)

The volume are in the ratio \(20:27\)

\(\frac{V_1}{V_2} =\frac{20}{27}\\\\\frac{\pi r_1^2h_1}{\pi r_2^2h_2} =\frac{20}{27}\\\\\frac{ r_1^2}{ r_2^2}\times \frac{3}{5} =\frac{20}{27}\\\\\frac{ r_1^2}{ r_2^2} =\frac{4}{9}\\\\\frac{ r_1}{ r_2} =\frac{2}{3}\)

The ratio of their radius is \(2:3\)

Answer:

2 : 3

Step-by-step explanation:

Let,

Radius of cylinder 1 = R

Radius of cylinder 2 = r

Now,

We know that

Volume of cylinder = πr²h

=> πR²h/πr²h' = 20/27

=> R² × 5/r² × 3 = 20/27

=> R²/r² = 20/27 × 3/5

=> R²/r² = 4/9

=> R/r = √(4/9)

=> R/r = 2/3

=> R : r = 2 : 3

The probability that this team will win both of their next two games is 16%

The probability of Allie's hockey team winning both of their next two games can be calculated by multiplying the probability of winning each individual game.

Since the team has a 40% chance of winning each game, the probability of winning both games is:

0.40 * 0.40 = 0.16

Therefore, the probability of Allie's team winning both of their next two games is 0.16, or 16%.

To express this answer as a percent, simply multiply by 100:

0.16 * 100 = 16%
