Function $C$ is defined on positive integers as follows:
\[C(n) = \begin{cases}
\dfrac n 2 & \text{if $n$ is even}, \\
3n+1 & \text{if $n$ is odd}.
\end{cases}\]Find the smallest positive integer $m$ such that $C^{m}(9) = 1$. What does this notation mean?
The smallest positive Integer m such that $C^{m}(9) = 1$ is m = 6.
The given function C is defined on positive integers as follows:$C(n) = \begin{cases}\dfrac n 2 & \text{if $n$ is even}, \\3n+1 & \text{if $n$ is odd}.\end{cases}$
The question is to find the smallest positive integer m such that $C^{m}(9) = 1$.
The notation $C^m(9)$ means applying the function C repeatedly m times to the number 9.
So, for example, $C^{2}(9)$ means applying the function C twice to the number 9, i.e., $C(C(9))$.
To solve this question, we will start by computing the first few iterations of the function C applied to 9, i.e., we will compute $C(9), C(C(9)), C(C(C(9))), C(C(C(C(9)))), \dots$.$C(9) = 3(9) + 1 = 28$.$C(C(9)) = C(28) = 28/2 = 14$.$C(C(C(9))) = C(14) = 14/2 = 7$.$C(C(C(C(9)))) = C(7) = 3(7) + 1 = 22$.$C(C(C(C(C(9))))) = C(22) = 22/2 = 11$.$C(C(C(C(C(C(9)))))) = C(11) = 3(11) + 1 = 34$.$C(C(C(C(C(C(C(9))))))) = C(34) = 34/2 = 17$.
We can see that $C^{6}(9) = 1$.
Therefore, the smallest positive integer m such that $C^{m}(9) = 1$ is m = 6.

if we select 4 young american men at random, what is the probability that they are all 68 inches or shorter (that is, each one of them is 68 inches or shorter)? enter your answer as a numerical value rounded to three decimal places (for ex., 0.111, no text).
The estimated probability that all four randomly selected young American men are 68 inches or shorter is approximately 0.004 or 0.4%.
To calculate the probability that all four randomly selected young American men are 68 inches or shorter, we need to consider the probability for each individual man and multiply them together.
Let's assume that the probability of an individual young American man being 68 inches or shorter is p. Since we are selecting four men at random, the probability of each man being 68 inches or shorter is the same, and we can multiply their probabilities together.
The probability of one man being 68 inches or shorter is p. Therefore, the probability of all four men being 68 inches or shorter is p × p × p × p = p^4.
However, we are not given the specific value of p in the problem statement. If we assume that the height of young American men follows a normal distribution, we can look up the corresponding z-score for a height of 68 inches or shorter and use the standard normal distribution to estimate the probability.
For example, if we find that a height of 68 inches corresponds to a z-score of -1.0, we can use a standard normal distribution table or a calculator to determine the probability of a z-score less than or equal to -1.0. Let's say this probability is approximately 0.1587.
Therefore, the estimated probability that all four randomly selected young American men are 68 inches or shorter would be (0.1587)^4 = 0.004.
Thus, the probability is approximately 0.004 or 0.4% rounded to three decimal places.

I ate dinner at my favorite restaurant, The Lazy Dog
Cafe. My bill came to $27.60 and I left a 20% tip. What
was the total I paid?
27
Answer:
The total that you paid was $33.12
Step-by-step explanation:
The tip was 20% of 27.60 so,
20/100 = x/27.60 = (0.2)(27.60) = x
x = 5.52
hence the tip was $5.52
so the total that you paid was,
Total = bill + tip
Total = 27.6 + 5.52
Total = $33.12
Answer: 33.12
20% of 27.60 is 5.52, so add 5.52 to 27.60.

what is (f−g)(x)? f(x)=3x5 6x2−5 g(x)=2x4 7x2−x 16 enter your answer in standard form in the box.
Answer:
(f - g)(x) = 3x^5 - 2x^4 - x^2 + x - 11 in standard form.
Step-bystep-Explanation:
To find (f - g)(x), we need to subtract the function g(x) from the function f(x) by subtracting the corresponding terms.
Given:
f(x) = 3x^5 + 6x^2 - 5
g(x) = 2x^4 + 7x^2 - x + 16
To find (f - g)(x), we subtract each term of g(x) from the corresponding term of f(x):
(f - g)(x) = (3x^5 - 2x^4) + (6x^2 - 7x^2) + (-5 - (-x)) - 16
Simplifying this expression, we get:
(f - g)(x) = 3x^5 - 2x^4 + 6x^2 - 7x^2 + (5 + x) - 16
Combining like terms, we have:
(f - g)(x) = 3x^5 - 2x^4 - x^2 + x - 11
Therefore, (f - g)(x) = 3x^5 - 2x^4 - x^2 + x - 11 in standard form.

Minimize z=5x1+4x2 Subject to: 6x1+2x2≤24 x1+2x2≤6 −x1+x2≤1 x2≤2
By substituting the corner points into the objective function, we can compare the values of z and identify the minimum. The corner point with the lowest z value will give us the optimal solution.
To solve the given linear programming problem completely, we will follow the steps mentioned earlier. Let's go through the process in more detail:
Step 1: Identify the decision variables:
Let x1 and x2 be the decision variables representing the values we want to find that minimize z.
Step 2: Formulate the objective function:
The objective function is given as z = 5x1 + 4x2.
Step 3: Formulate the constraints:
The given constraints are:
6x1 + 2x2 ≤ 24
x1 + 2x2 ≤ 6
-x1 + x2 ≤ 1
x2 ≤ 2
Step 4: Combine all the constraints:
To combine the constraints, we rewrite them in standard form:
6x1 + 2x2 ≤ 24 ---> 6x1 + 2x2 + 0x3 + 0x4 = 24
x1 + 2x2 ≤ 6 ---> x1 + 2x2 + 0x3 + 0x4 = 6
-x1 + x2 ≤ 1 ---> -x1 + x2 + 0x3 + 0x4 = 1
0x1 + x2 ≤ 2 ---> 0x1 + x2 + 0x3 + 0x4 = 2
Step 5: Solve the linear programming problem:
To solve this linear programming problem, we can use various methods such as the Simplex method or graphical method. Here, we'll use the graphical method to find the optimal solution.
First, let's plot the feasible region by graphing the equations of the constraints:
Plotting 6x1 + 2x2 = 24:
x1 | x2
0 | 12
4 | 0
Plotting x1 + 2x2 = 6:
x1 | x2
0 | 3
6 | 0
Plotting -x1 + x2 = 1:
x1 | x2
-1 | 0
0 | 1
Plotting x2 = 2:
x1 | x2
0 | 2
Next, we need to find the feasible region by considering the overlapping shaded area formed by the inequalities. However, I cannot provide a visual representation here. Please refer to a graphing tool or software to plot the equations and find the feasible region.
Finally, we evaluate the objective function z = 5x1 + 4x2 at the corner points of the feasible region to determine the minimum value of z. Each corner point represents a specific combination of x1 and x2 within the feasible region.
By substituting the corner points into the objective function, we can compare the values of z and identify the minimum. The corner point with the lowest z value will give us the optimal solution.
Please note that without the graphical representation, I am unable to provide the exact numerical solution. I recommend using a graphing tool or linear programming software to visualize the feasible region and determine the optimal values of x1 and x2 that minimize z.

To calculate the Y* coordinate of the weighted center of gravity for the new fire station, we need additional information regarding the locations and population sizes of the four neighborhoods in Green Valley, Arizona. Once we have this information, we can calculate the weighted center of gravity by considering the population of each neighborhood as the weight and using the formula Σ(xi * wi) / Σwi, where xi represents the Y-coordinate of each neighborhood and wi represents the population weight.
In order to calculate the Y* coordinate of the weighted center of gravity for the new fire station, we require the Y-coordinates and population sizes of the four neighborhoods in Green Valley, Arizona. With this information, we can proceed to calculate the weighted center of gravity using the following formula:
Y* = Σ(xi * wi) / Σwi
where xi represents the Y-coordinate of each neighborhood and wi represents the population weight of each neighborhood.
The Y* coordinate obtained will represent the vertical position of the weighted center of gravity. It indicates the optimal location for the new fire station, taking into account the population distribution in the area.
However, since the exact locations and population sizes of the neighborhoods have not been provided, it is not possible to calculate the Y* coordinate of the weighted center of gravity in this scenario. To determine the optimal location for the fire station, the city of Green Valley, Arizona, would need to gather the necessary data on neighborhood locations and population sizes, and then apply the formula mentioned above.

person and he has to
pay the DJ $180 for
the night. How many
people attended if he
ended up with $500
when the night was
over?
Answer: 32 people
Step-by-step explanation:
500-180=320
320/10=32
Answer:68 People
Step-by-step explanation: This is because if he ended up with $500 by the end of the night, this is after he paid the DJ. So we assume he paid the DJ so we add $180 to what he ended up with that night. That adds up to $680 so $680 is the amount he made that night from the people coming in. Divide that by 10 to get the amount of people, and you get 68. So 68 people came to his party.

Jeremy's weighted average for his human biology course is 83.6%.
To calculate Jeremy's weighted average, we need to apply the respective weights to each category and then sum them up.
Tests: 50% of the final grade
Quizzes: 35% of the final grade
Homework: 15% of the final grade
To find the weighted average, we multiply each category's average by its respective weight and then sum the results.
Tests: 94% * 50% = 47%
Quizzes: 78% * 35% = 27.3%
Homework: 62% * 15% = 9.3%
Adding up the weighted scores:
47% + 27.3% + 9.3% = 83.6%
Jeremy's weighted average for his human biology class is 83.6% as a result.
