Part A: -6 and -1

Part B: (x - 6)(x - 1) = 0

Part C: x = 6 and x = 1

    We need to find two numbers that add up -7 and multiply to 6.

    We know that 6 * 1 = 6, but 6 + 1 is not -7. However, -6 * -1 = 6 and -6 + -1 = -7. Our factors are -6 and -1.

    Next, we will rewrite this in factored form. Using the factors above, the form is as follows.

(x - 6)(x - 1) = 0

    Lastly, we will use the zero product property to solve. This states that if xy = 0, then x = 0 and y = 0 because anything times zero is equal to zero.

x - 6 = 0       x - 1 = 0

x = 6             x = 1

Watershed should offer the promotion to the top 70 customers to maximize their profit from the intervention campaign.

To determine the optimal number of customers to offer the promotion to, Watershed should start by offering it to customers with the highest estimated unsubscribe probability and work their way down until the promotion budget is exhausted. This approach will maximize the chances of persuading customers who are most likely to unsubscribe.

Let's assume that Watershed has a budget of $1000 to spend on promotions. This means they can offer the promotion to a maximum of 100 customers (1000/10).

To calculate the expected profit, we need to consider the probability of a customer unsubscribing, the probability of the promotion persuading them to remain a customer, and the value of retaining a customer and offering a promotion.

If a customer unsubscribes and is not persuaded to remain, the cost to Watershed is $10. If they unsubscribe but are persuaded to stay, the value to Watershed is $50 ($60-$10). If they don't unsubscribe, the cost is $0.

Using the formula given, we can calculate the profit for different values of n (the number of customers offered the promotion):

n = 10:
Profit = 10 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $460

n = 20:
Profit = 20 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $780

n = 30:
Profit = 30 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $990

n = 40:
Profit = 40 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1090

n = 50:
Profit = 50 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1150

n = 60:
Profit = 60 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1180

n = 70:
Profit = 70 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1190

n = 80:
Profit = 80 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1180

n = 90:
Profit = 90 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1150

n = 100:
Profit = 100 * (0.6 * 50 + 0.4 * (-10)) + 0 * (-10) = $1100

From the calculations above, we can see that the maximum profit of $1190 occurs when the promotion is offered to 70 customers. Beyond this point, the cost of offering the promotion to less likely churners outweighs the benefit of retaining those customers.

Therefore, Watershed should offer the promotion to the top 70 customers to maximize their profit from the intervention campaign.

d. the expected value of buying a ticket is -$1.19, which means on average, a person can expect to lose $1.19 by buying a ticket.
e.the expected return to the club is $100 if all 80 tickets are sold.

a. John Underpar's possible monetary outcomes are either winning the Taylormade R9 10.5 regular flex driver, which is worth $300, or having a worthless ticket, which is worth -$5 (the cost of the ticket).

b. Actually, winning the driver is worth $300, not $295. So, Mr. Underpar's possible monetary outcomes are either winning the driver (worth $300) or having a worthless ticket (worth $0).

c. Mr. Underpar's "experiment" can be summarized as a probability distribution with the following probabilities:

Probability of getting nothing = 79/80 = 0.9875
Probability of winning the driver = 1/80 = 0.0125

d. The mean or expected value of the probability distribution can be calculated as:

Expected value = (Probability of winning the driver x Value of winning) + (Probability of getting nothing x Value of nothing)
Expected value = (0.0125 x $300) + (0.9875 x -$5)
Expected value = $3.75 - $4.94
Expected value = -$1.19

Therefore, the expected value of buying a ticket is -$1.19, which means on average, a person can expect to lose $1.19 by buying a ticket.

e. If all 80 tickets are sold, the expected return to the club can be calculated as:

Expected return = (Number of tickets sold x Price of a ticket) - Value of the prize
Expected return = (80 x $5) - $300
Expected return = $400 - $300
Expected return = $100

Therefore, the expected return to the club is $100 if all 80 tickets are sold.

A function is a relationship with unique x-values.

Defining a Function

For a relationship to be a function, the x-values cannot repeat. This means that inputs, aka x-values, can only have one possible output value, also called y-values. For example, if inputting x = 5 resulted in both y = 3 and y = 7, then the relationship would not be a function.

However, y-values do not have to be unique. Functions can repeat y-values and still be functions.

Answers

Now, let's apply this definition to the problems above.

1. The first question gives us a table of x and y-values. From the x-values in the left column, we can see that x-values do not repeat. This means the relationship is a function.

2. The second question gives the inputs and outputs of a function. From looking at the outputs for 0, we can tell that x = 0 produces multiple outputs. This means that not all x-values are unique. Thus, the relationship is not a function.

3. The third image is a graph. At no point on the graph do x-values repeat. Each x-value has one y-value. So, the relationship is a function. Specifically, this graph represents a quadratic function.

Of the options given, cofilin would be expected to increase the rate of actin depolymerization on the minus end of the filament.

The depolymerization of actin filaments is a dynamic process that is regulated by a variety of proteins. Actin filaments grow by the addition of ATP-G-actin subunits to the plus end of the filament and can depolymerize from the minus end. Several proteins regulate actin depolymerization by binding to actin filaments and promoting filament disassembly. Of the options given, cofilin would be expected to increase the rate of actin depolymerization on the minus end of the filament.

Cofilin is a small actin-binding protein that binds to ADP-actin subunits within the filament, inducing a conformational change that destabilizes the filament and promotes depolymerization. Cofilin binds preferentially to the ADP-bound subunits, which are found primarily at the minus end of the filament. By binding to these subunits, cofilin promotes the disassembly of the filament from the minus end, increasing the rate of depolymerization.

In contrast, ATP-G-actin is the monomeric form of actin that is added to the plus end of the filament and promotes filament growth. Cap Z is a capping protein that binds to the plus end of the filament, stabilizing it and preventing depolymerization. Profilin is an actin-binding protein that binds to ATP-G-actin, promoting its polymerization into filaments. Thymosin β4 is a protein that binds to actin monomers, preventing their polymerization into filaments and sequestering them in the cytoplasm.

P(X = k) = 4p^3(1 - p)   for k = 3
P(X = k) = p^4   for k = 4

Note that these probabilities add up to 1, as they should for any probability distribution.

(a) The distribution of X can be modeled as a binomial distribution with parameters n = 4 and p, where p is the probability that the friend correctly identifies a milk-first cup as milk-first. Each cup that the friend tastes can either be identified correctly (success) or incorrectly (failure), and there are 4 cups that were poured milk-first in the experiment.

(b) To find the probability mass function (PMF) of X, we need to find the probability of each possible value of X. Since X is a binomial random variable, the PMF of X is given by:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where (n choose k) is the binomial coefficient, given by:

(n choose k) = n! / (k! * (n - k)!)

where n! denotes the factorial of n.

In this case, n = 4 and there are 4 cups that were poured milk-first, so we have:

P(X = 0) = (4 choose 0) * p^0 * (1 - p)^4 = (1 - p)^4

P(X = 1) = (4 choose 1) * p^1 * (1 - p)^3 = 4p(1 - p)^3

P(X = 2) = (4 choose 2) * p^2 * (1 - p)^2 = 6p^2(1 - p)^2

P(X = 3) = (4 choose 3) * p^3 * (1 - p)^1 = 4p^3(1 - p)

P(X = 4) = (4 choose 4) * p^4 * (1 - p)^0 = p^4

Since X can only take on values between 0 and 4, the PMF of X is given by:

P(X = k) = (1 - p)^4   for k = 0
P(X = k) = 4p(1 - p)^3   for k = 1
P(X = k) = 6p^2(1 - p)^2   for k = 2

A = π(6)²/6

A = 6π

So,

The total area of the spinner is π(6)² = 36π.

So the probability of the randomly selected point falling in the green sector is:

To find the approximate increase in the area when the radius increases from r₁ mm to r₂ mm, we can calculate the difference between the areas by subtracting the initial area (A₁ = πr₁²) from the final area (A₂ = πr₂²). This can be expressed as ΔA = A₂ - A₁ = πr₂² - πr₁².

In the second paragraph, let's explain the formula and how to calculate the approximate increase in the area of the bacterial colony on the petri dish. The area of a circular shape is given by the formula A = πr², where "A" represents the area and "r" represents the radius. By substituting the initial radius, r₁, into the formula, we can find the initial area, A₁ = πr₁².

Similarly, by substituting the final radius, r₂, into the formula, we can find the final area, A₂ = πr₂². To calculate the approximate increase in area, we subtract the initial area from the final area: ΔA = A₂ - A₁ = πr₂² - πr₁².

Using the concept of inverse variation and provide a solution using the appropriate formula.
The intensity (I) of a light source is inversely proportional to the square of the distance (d) from the source. If the intensity of the light source is 100 units when the distance is 2 meters, what is the intensity when the distance is 5 meters?

The inverse variation formula can be written as I = k / d^2, where I is the intensity, d is the distance, and k is the constant of proportionality.

Determine the constant of proportionality (k) using the initial values.
I = 100 units, d = 2 meters
100 = k / (2^2)
100 = k / 4
k = 400

Use the formula with the new distance (5 meters) to find the new intensity.
I = 400 / (5^2)
I = 400 / 25
I = 16 units

The conclusion is stated as:
When the distance from the light source is increased to 5 meters, the intensity of the light decreases to 16 units. This problem demonstrates the concept of inverse variation, as the intensity of the light source is inversely proportional to the square of the distance from the source.

From the table, we can see that the revenue initially increases as the fee rate decreases, but then starts to decrease after $7.50. This is because although the number of subscribers increases with a lower fee rate, the decrease in revenue from each individual subscriber outweighs the increase in subscribers.

Therefore, the fee rate that would maximize revenue for the online computer game company is $7.50. This is the fee rate where the revenue is the highest, at $82,500. We know this is the optimal fee rate because any higher fee rate will result in fewer subscribers, and any lower fee rate will result in a decrease in revenue per subscriber.

It took Donna 30 months to pay off her credit card.

Total amount paid = Monthly payment x Number of months

Total amount paid = $104 x Number of months

Amount paid towards principal = Total amount paid - Total interest paid - Original amount owed

We know that she paid $126 in interest and originally owed $3,000, so we can substitute those values:

Amount paid towards principal = Total amount paid - $126 - $3,000

= $104 x Number of months - $126 - $3,000

We want to know how many months it takes for her to pay off the entire debt, so we can set the amount paid towards principal equal to zero:

$104 x Number of months - $126 - $3,000 = 0

$104 x Number of months = $3,126

Number of months = $3,126 / $104

Number of months = 30.1

So it took Donna 30 months to pay off her credit card.

If an expression for x that does not use an absolute value is y, rewrite |x-y| as x - y.

It is the same as rearranging one expression to plug it into another expression when rewriting algebraic expressions using structure. Solving for one of the variables and then plugging the resulting expression for that variable into the other expression is the initial step to take in these kinds of issues.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
