Fill the Blank ; A distribution in which all the values have the same frequency is called a(n) ______ distribution.

The recursive function adds the last term of the summation to the recursive call with n-1 as the input. The final solution is the result of the recursive function for the input value n.

To write a recursive function to compute the summation sum( ((-1)^x)*x*x, x=1..n), we need to break down the summation into smaller parts.
We can start by defining a base case for the recursive function. When n is equal to 1, the summation will only have one term, which is (-1)^1 * 1 * 1. So, the base case would be:
if n == 1:
   return -1
Next, we need to find a way to express the summation in terms of smaller parts. We can observe that the summation can be expressed as:
((-1)^n) * n * n + sum((-1)^(x-1) * (x-1) * (x-1), x=1..n-1)
Notice that the summation term on the right-hand side is similar to the original summation, but with n-1 as the upper limit of the summation. This allows us to use recursion to calculate the summation:
def recursive_sum(n):
   if n == 1:
       return -1
   else:
       return ((-1)**n) * n * n + recursive_sum(n-1)
This recursive function computes the summation by adding the last term of the summation ((-1)^n * n * n) to the recursive call with n-1 as the input. This process continues until the base case is reached.
In summary, the recursive function to compute the summation sum( ((-1)^x)*x*x, x=1..n) is:
def recursive_sum(n):
   if n == 1:
       return -1
   else:
       return ((-1)**n) * n * n + recursive_sum(n-1)
Answer: The solution to this question involves writing a recursive function to compute the summation sum( ((-1)^x)*x*x, x=1..n). To do this, we need to define a base case and express the summation in terms of smaller parts. The recursive function adds the last term of the summation to the recursive call with n-1 as the input. The final solution is the result of the recursive function for the input value n.

[tex]\frac{6}{8}[/tex]   and   [tex]\frac{3}{4}[/tex]   are equivalent fractions.

The aggregate demand curve shifts to the left, indicating a decrease in overall demand in the economy.

A decrease in U.S. net exports would result in a decrease in aggregate demand.

This is because net exports are a component of aggregate demand, which is the total amount of goods and services demanded in an economy.

When net exports decrease, it means that fewer goods and services are being exported from the U.S.

This, in turn, means that there is less demand for U.S. goods and services from foreign buyers.

As a result, the aggregate demand curve shifts to the left, indicating a decrease in overall demand in the economy.

Represents the vector f + g.  C.

The sum of two vectors, we simply add their corresponding components.

In this case,
f + g = (4 - 1, 3 + 0, 7 + 2) = (3, 3, 9)
So the resulting vector has components (3, 3, 9).
Now we need to find the graph that represents this vector.

Graphing a vector in three dimensions can be challenging, but we can use the following method:
Start at the origin (0, 0, 0) of the 3D coordinate system.
Move 3 units in the x-direction, 3 units in the y-direction, and 9 units in the z-direction.
Mark the endpoint of this displacement as the tip of the vector.

Option A has a similar direction, but it is longer than f + g.

Option B has the correct length, but it is pointing in the wrong direction.

Option D is pointing in the correct direction, but it is too short.

We only add the respective components of the two vectors to get their sum.

Thus, f + g = (4 - 1, 3 + 0, 7 + 2) = (3, 3, 9) in this situation.

The resultant vector has three (3), three (3), and nine (9).

We now need to identify the graph that this vector is represented by.

It might be difficult to graph a vector in three dimensions, however we can try the following approach:

Start at the 3D coordinate system's origin (0, 0, 0).

Move three units in the x, three units in the y, and nine units in the z directions.

The question is incomplete, the complete question is:

According to the probability, we expect approximately 12 or 13 of the 20 cards to have flowers on them.

To calculate the probability of selecting four cards with no flowers on them, we can first determine the number of ways to choose four cards from the 16 non-flower cards in the package. This is:

16C4 = 16! / (4! * (16-4)!) = 1820

Therefore, there are 1,820 different ways to choose four cards with no flowers on them.

To find the probability of selecting four cards with no flowers on them, we can divide the number of ways to choose four non-flower cards by the total number of ways to choose any four cards:

P(4 non-flower cards) = 1,820 / 4,845 = 0.375

So the probability of selecting four cards with no flowers on them is 0.375.

To find the probability of selecting at least one card with flowers on it, we can subtract the probability of selecting four non-flower cards from 1:

P(at least one flower card) = 1 - P(4 non-flower cards) = 1 - 0.375 = 0.625

Therefore, the probability of selecting at least one card with flowers on it is 0.625.

To answer the original question, we can use this probability to estimate how many of the 20 cards we would expect to have flowers on them. We can multiply the probability by the total number of cards in the package:

Expected number of cards with flowers = 0.625 x 20 = 12.5

To find the length of the arc intercepted by a central angle of 7π/4 radians, we use the formula:

arc length = radius * central angle

In this case, the radius is given as 22 m and the central angle is 7π/4 radians. Substituting these values in the formula, we get:

arc length = 22 * 7π/4

= 38.5π

Now, we need to approximate this value using 3.14 for π. Therefore, we get:

arc length ≈ 38.5 * 3.14

As n increases from 2 to 10, the mean of the sampling hdistribution of the sample mean will increase, while the variance and standard error of the mean will decrease.

As n increases from 2 to 10, the sampling distribution of the sample mean will shift towards the population mean of 22.4 minutes. This is because as n increases, the sample mean becomes a better estimate of the population mean. Therefore, the mean of the sampling distribution will increase.

However, the variance of the sampling distribution will decrease as n increases. This is because the larger the sample size, the more representative the sample is of the population, and thus the less variability there is in the sample means. Therefore, the variance of the sampling distribution will decrease.

It is important to note that the standard error of the mean, which is the standard deviation of the sampling distribution, will also decrease as n increases. This means that as the sample size increases, the sample mean becomes a more precise estimate of the population mean.

In summary, as n increases from 2 to 10, the mean of the sampling distribution of the sample mean will increase, while the variance and standard error of the mean will decrease.

Laverne starts counting out loud by 5's, beginning with 7. Shirley sums up all the numbers that Laverne says until the sum exceeds 5000. We need to find the number that Laverne says that sends Shirley screaming and running.

To solve this problem, we can start by finding the pattern in Laverne's counting. She is counting by 5's, so each number she says is 5 more than the previous one. Therefore, we can create an arithmetic sequence with a first term of 7 and a common difference of 5. The formula for the nth term of an arithmetic sequence is given by:

a_n = a_1 + (n-1)d

where a_n is the nth term, a_1 is the first term, d is the common difference, and n is the number of terms.

To find the number that Laverne says that sends Shirley screaming and running, we need to find the value of n such that the sum of the first n terms of the sequence is greater than 5000. We can use the formula for the sum of an arithmetic sequence to do this:

S_n = n/2(2a_1 + (n-1)d)

where S_n is the sum of the first n terms.

Using the values given in the problem, we can write the equation:

n/2(2(7) + (n-1)(5)) > 5000

Simplifying and solving for n, we get:

n > 398

Therefore, the number that Laverne says that sends Shirley screaming and running is the 398th term in the sequence. We can find this term by plugging in n = 398 into the formula for the nth term:

a_398 = 7 + (398-1)(5) = 1989

So, Laverne says the number 1989 that sends Shirley screaming and running.

To determine the minimum number of customer service representatives needed to achieve an average waiting time of 2 minutes, we can use the M/M/1 queuing model formula:

where L is the average number of customers waiting in the queue, λ is the arrival rate (calls per minute), and W is the average time a customer spends waiting in the queue.

First, we need to convert the arrival rate from every 7 minutes to arrivals per minute:

Next, we need to find the service rate, which is the reciprocal of the service time:

The utilization factor (ρ) is calculated as the ratio of arrival rate to service rate:

Using Little's Law, we can calculate the average number of customers in the system:

This negative value implies that the system is unstable and would result in an infinite queue. Therefore, we need to increase the number of customer service representatives to reduce the average waiting time.

Assuming we want to achieve an average waiting time of 2 minutes, we can rearrange the formula to solve for the minimum number of customer service representatives (n):

n = (ρ² + ρ) / (2 * (1 - ρ) * (1 - 2 * ρ * [tex]e^{(-p/2)}[/tex]))

Now, let's take a look at the information given to us. We know that the radius of the circle is 0.84 inches. The radius is the distance from the center of the circle to its edge, and it is half the length of the diameter. So, we can find the diameter by multiplying the radius by 2, which gives us a diameter of 1.68 inches.

We also know that the circumference of the circle is 5.28 inches. The circumference is the distance around the edge of the circle. We can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference, π is the value of pi, and r is the radius.

We can rearrange this formula to solve for π, which gives us π = C/2r. Plugging in the values we know, we get π = 5.28/2(0.84) = 3.14.
