Answer:

w = \(\frac{p -2l}{2}\)

Step-by-step explanation:

p = 2l + 2w  Subtract 2l from both sides of the equation

p - 2l = 2p  Divide both sides by 2

\(\frac{p -2l}{2}\) = w

The mean of the batting averages is 0.341125.

Mean is used to summarize a set of data, frequently to help determine the overall significance of the data set.

To find the mean of the batting averages, we need to sum up all the batting averages and divide by the total number of players.

Batting averages: .373, .360, .321, .321, .320, .312, .311, .311

Sum of batting averages = .373 + .360 + .321 + .321 + .320 + .312 + .311 + .311

Sum of batting averages = 2.729

Now, we divide the sum by the total number of players, which is 8:

Mean = Sum of batting averages / Total number of players

Mean = 2.729 / 8

Calculating the mean:

Mean ≈ 0.341125

The mean of the batting averages is approximately 0.341125.

x is equal to six

Step-by-step explanation:

4 × 6 = 24

Answer: There is only one step to this equation. We will use inverse operations to isolate the x by dividing 4 on both sides. (4 is being multiplied by x, and the opposite of multiplication is division.)

4x/4 = x

24/4 = 6

The equation now looks like:

x = 6

x is equal to 6, so this is your answer.

The angle theta that the vector makes with the positive x-axis is 60°.

To find the magnitude of the vector W = 4i + 4√3j, we use the formula:

|W| = sqrt((x^2) + (y^2))

In this case, x = 4 and y = 4√3. Substituting these values into the formula:

|W| = sqrt((4^2) + (4√3^2))

= sqrt(16 + 48)

= sqrt(64)

= 8

Therefore, the magnitude of vector W is 8.

To find the angle theta that the vector makes with the positive x-axis, we use the formula:

theta = atan(y/x)

In this case, x = 4 and y = 4√3. Substituting these values into the formula:

theta = atan(4√3/4)

= atan(√3)

= 60°

Therefore, the angle theta that the vector makes with the positive x-axis is 60°.

To find the dimension of the eigenspace corresponding to each eigenvalue, we need to solve the equation (dim(x) - 1.1) = 0. In this case, there is no valid dimension for the eigenspace.

1. The equation dim(x) - 1.1 = 0 tells us that the dimension of the eigenspace (denoted by dim(x)) is equal to 1.1. However, dimensions must be whole numbers, so we cannot have a fractional dimension for an eigenspace. Therefore, in this case, there is no valid dimension for the eigenspace.

2. The concept of eigenspaces and their dimensions is typically associated with eigenvalues of matrices. However, in this case, you provided an equation involving the dimension of the eigenspace directly, without specifying any matrix or eigenvalues. As a result, we cannot provide specific eigenvalues or dimensions for eigenspaces without additional information.

The volume of the resulting solid is (26π/3) cubic units.

To find the volume of the solid generated by rotating the region bounded by the curves x = (y - 6)², x = 25, about the axis y = 1, we will integrate the cylindrical shells along the y-axis.

The limits of integration for y are from y = 1 to y = 11, as determined earlier.

The differential volume of a cylindrical shell is given by dV = 2πrh dy, where r is the distance from the axis of rotation to the curve, h is the height of the cylindrical shell, and dy is the thickness of the shell.

In this case, the radius of the cylindrical shell is r = 1, and the height of the cylindrical shell is h = x₁ - x₂ = 25 - (y - 6)².

Thus, the differential volume becomes dV = 2π(1)(25 - (y - 6)²) dy.

We can now integrate this differential volume over the range of y = 1 to y = 11 to find the total volume V:

V = ∫[1,11] 2π(25 - (y - 6)²) dy

Expanding and simplifying the integral:

V = 2π ∫[1,11] (25 - (y - 6)²) dy

V = 2π ∫[1,11] (25 - (y² - 12y + 36)) dy

V = 2π ∫[1,11] (25 - y² + 12y - 36) dy

V = 2π ∫[1,11] (-y² + 12y - 11) dy

Integrating the terms individually:

V = 2π [-y³/3 + 6y² - 11y] |[1,11]

V = 2π [-(11³/3) + 6(11²) - 11(11)] - [-(1³/3) + 6(1²) - 11(1)]

V = 2π [-1331/3 + 726 - 121] - [-1/3 + 6 - 11]

V = 2π [-1331/3 + 726 - 121 + 1/3 - 6 + 11]

V = 2π [-604/3 + 616 + 1/3]

V = 2π [13/3]

Simplifying further:

V = (26π/3)

Therefore, the volume of the resulting solid is (26π/3) cubic units.

At the bus station, there are eight lines for arriving passengers, each staffed by a single worker. The arrival rate for passengers is 124 per hour, which means the arrival rate per minute is 124/60 = 2.067 passengers per minute. Each passenger takes an average of 3 minutes for a worker to process, so the service rate per worker is 1/3 = 0.333 customers per minute.

Since there are eight workers, the combined service rate for all workers is 8 * 0.333 = 2.664 customers per minute. The coefficient of variation for arrival time is 1.4, and the coefficient of variation for service time is 1.

To find the average number of customers in the queue, we can use the formula:

Lq = (Ca^2 + Cs^2) * (λ^2) / (2 * (µ - λ))

Where Lq is the average number of customers in the queue, Ca is the coefficient of variation for arrival time, Cs is the coefficient of variation for service time, λ is the arrival rate, and µ is the service rate.

Lq = (1.4^2 + 1^2) * (2.067^2) / (2 * (2.664 - 2.067))
Lq = (1.96 + 1) * (4.276) / (2 * 0.597)
Lq ≈ 7.34 customers in the queue

To find the average time a customer spends in the queue, we can use the formula:

Wq = Lq / λ

Wq = 7.34 / 2.067
Wq ≈ 3.55 minutes

On average, customers spend approximately 3.55 minutes in the queue.

Step-by-step explanation:

The Normal model is a good approximation for the sampling distribution.

a) According to the Central Limit Theorem, the theoretical mean and standard deviation for a sample size of 20 should be 0.05 and 0.02, respectively. For a sample size of 100, the theoretical mean and standard deviation should be 0.05 and 0.01, respectively.

b) The observed mean and standard deviation for a sample size of 20 was 0.052 and 0.021, respectively. For a sample size of 100, the observed mean and standard deviation was 0.051 and 0.012, respectively. These values are fairly close to the theoretical values.

c) Looking at the histograms in Exercise 1, I would be comfortable using the Normal model as an approximation for the sampling distribution at a sample size of 100.

d) The Success/Failure Condition states that the sample size should be large enough for the sampling distribution of the sample proportions to be approximately normal. Since I chose a sample size of 100, which satisfied the condition, I can be confident that the Normal model is a good approximation for the sampling distribution.

The sample size of 100 is large enough for the sampling distribution of the sample proportions to be approximately normal, and the observed mean and standard deviation is close to the theoretical values. Therefore, the Normal model is a good approximation for the sampling distribution.

Step-by-step explanation:

Max will be able to wash 27 cars in 6 hours. This means that his washing rate is 4.5 cars per hour (since 9 cars divided by 2 hours is equal to 4.5 cars per hour).

We can start by figuring out how many cars Max can wash in one hour.
To do this, we can use a proportion:
9 cars / 2 hours = x cars / 1 hour
Solving for x, we get:
x = (9 cars / 2 hours) * (1 hour / 1)
x = 4.5 cars/hour
So we know that Max can wash 4.5 cars in one hour.
To find out how many cars he can wash in 6 hours, we can multiply the number of cars he can wash in one hour by the number of hours he will be working:
4.5 cars/hour * 6 hours = 27 cars
Therefore, Max will be able to wash 27 cars in 6 hours.

Max works at a local car wash and he can wash 9 cars every 2 hours.
Now, we need to figure out how many cars Max can wash in 6 hours. To do this, we can use the formula:
Number of cars = Rate * Time
where Rate is the number of cars Max can wash per hour, and Time is the number of hours he will be working.
So, in this case, we have:
Number of cars = 4.5 cars/hour * 6 hours
Number of cars = 27 cars
Therefore, Max will be able to wash 27 cars in 6 hours.

Answer:To evaluate the exponential expression 6(4+2)² - 32, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, we simplify the expression inside the parentheses:

4 + 2 = 6

Next, we square the result:

6² = 36

Now, we substitute the squared result back into the expression:

6(36) - 32

Next, we perform the multiplication:

6 * 36 = 216

Finally, we subtract 32:

216 - 32 = 184

Therefore, the value of the given exponential expression 6(4+2)² - 32 is 184.
