C=S0N(d1)−Ke^(−rT)N(d2)
Where,C is the price of the call option,N(d) is the cumulative probability distribution function of the standard normal distribution evaluated at the value d.Using the above values, the price of a call option can be computed as:
C=85N(-0.0985)−90e^(−0.06×1)N(-0.2785)=2.9312
d) Calculation of the price of a put option in the Black-Scholes-Merton model:The formula to calculate the price of a put option is given by the expression:
P=Ke^(−rT)N(-d2)−S0N(-d1)
Where,P is the price of the put option, andN(d) is the cumulative probability distribution function of the standard normal distribution evaluated at the value d.
Using the above values, the price of a put option can be computed as:
P=90e^(−0.06×1)N(-(-0.2785))−85N(-(-0.0985))=7.4279
Therefore, the value of d1 is -0.0985, the value of d2 is -0.2785, the price of a call option is 2.9312, and the price of a put option is 7.4279.

He determined that the differences of 6, 10, and 14 are increasing by 4 each time.
O He concluded that the function has a constant rate of change.
O He reasoned that a function that has a constant rate of change
Willis's mistake is assuming that a constant difference in the y-values implies a constant rate of change, which is not necessarily true for non-linear functions.
While it is true that a linear function will always have a constant rate of change, the converse is not true. A non-linear function can also have a constant difference in the y-values over a certain interval, but the rate of change is not constant. This is because the rate of change of a non-linear function varies at different points along the curve.
In this case, Willis did not consider the possibility of a non-linear function with a constant difference in the y-values. Therefore, his conclusion that the function is linear based on the constant differences in the y-values is not necessarily correct. To determine whether the function is linear or non-linear, Willis should have examined the differences in the x-values as well, or plotted the points on a graph to see if they lie on a straight line.
Imogen has 2 toy elephants and 7 toy bears in a box. She picks a toy at random and does not replace it. She then picks a second toy at random. Draw a tree diagram to work out the probability that the second toy she chooses will be a different type of animal to the first toy. Give your answer as a fraction in its simplest form.
The probability of choosing a different type of animal as the second toy is $\frac{7}{18}.
The problem is to draw a tree diagram to determine the probability of choosing a different type of toy animal when two toys are randomly selected. Imogen has two toy elephants and seven toy bears in a box.
It should be noted that a tree diagram is a visual tool that can be used to show the possible outcomes of a particular event. Each branch represents a possible outcome and the probabilities associated with each branch are assigned in the diagram. The steps involved in solving the problem are:
Step 1: Construct the tree diagram.
Step 2: Calculate the probability of choosing a different type of animal as the second toy. Step 3: Simplify the fraction. Solution:
Step 1: Construct the tree diagram. The tree diagram for the given problem is shown below. [asy] size(200); defaultpen(linewidth(0.7)); draw((0,0)--(2,-2),MidArcArrow(size=10)); draw((0,0)--(2,2),MidArcArrow(size=10)); draw((2,2)--(4,2),MidArcArrow(size=10)); draw((2,-2)--(4,-2),MidArcArrow(size=10)); draw((2,2)--(4,0),MidArcArrow(size=10)); draw((2,-2)--(4,0),MidArcArrow(size=10)); draw((4,2)--(6,2),MidArcArrow(size=10)); draw((4,0)--(6,0),MidArcArrow(size=10)); draw((4,-2)--(6,-2),MidArcArrow(size=10)); label("Elephant",(-1,0)); label("Bear",(-1,2)); label("Bear",(3,2)); label("Bear",(3,0)); label("Bear",(3,-2)); label("Elephant",(3,0)); label("Bear",(5,2)); label("Elephant",(5,0)); label("Bear",(5,-2)); [/asy] Step 2: Calculate the probability of choosing a different type of animal as the second toy. The total number of outcomes is 9, as there are 2 elephants and 7 bears. There are four possible ways in which Imogen can pick two different types of animal:
Elephant followed by bear, Bear followed by elephant, Elephant followed by elephant, and Bear followed by bear. The probability of choosing a different type of animal as the second toy is the sum of the probabilities of the first two outcomes, which is: $P(\text{different animal}) = \frac{2}{9}\times\frac{7}{8}+\frac{7}{9}\times\frac{2}{8}$ $=\frac{14}{72}+\frac{14}{72}$ $=\frac{28}{72}$
Step 3: Simplify the fraction. The fraction can be simplified by dividing the numerator and denominator by the highest common factor. The highest common factor of 28 and 72 is 4. Hence, $\frac{28}{72} = \frac{7}{18}$
Therefore, the probability of choosing a different type of animal as the second toy is $\frac{7}{18}$.

The probability that the second toy Imogen chooses will be a different type of animal to the first toy is 7/18. This is calculated by determining the probability of picking an elephant then a bear, and the probability of picking a bear then an elephant, and adding these two probabilities.
Explanation:Firstly, let's define the event: Picking an elephant (E) and picking a bear (B). At the beginning, Imogen has 2 elephants and 7 bears in the box, making a total of 9 toys.
When Imogen picks the first toy, the probabilities are: P(E) = 2/9 and P(B) = 7/9. Then, Imogen picks the second toy, not replacing the first one.
So, we have two scenarios for the second pick: Given that the first pick was an elephant, the probabilities for the second pick are: P(E) = 1/8 (because one elephant left) and P(B) = 7/8 (there are still 7 bears). If the first pick was a bear, the probabilities for the second pick are: P(E) = 2/8 (still 2 elephants) and P(B) = 6/8 (one bear left).
Now, we're interested in the probability of picking two different types of animal toys. That will be the sum of the probabilities of picking an elephant then a bear, and the probability of picking a bear then an elephant. So it's (P(E) * P(B|E)) + (P(B) * P(E|B)) = (2/9 * 7/8) + (7/9 * 2/8) = 14/72 + 14/72 = 28/72 which reduces to 7/18.

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k. Two lines labeled f of x and g of x. Line f of x passes through points negative 4, 0 and negative 3, 1. Line g of x passes through points negative 4, 0 and negative 3, negative 2. Question 6Select one: a. −2 b. negative one half c. one half d. 2
As we can see, this is the equation of line `g(x)` that passes through the points `(-4,0)` and `(-3,-2)`. Therefore, the value of `k` is `2`.
The correct answer to the given question is option d.
We have the function `g(x) = k⋅f(x)`. The values of `f(x)` and `g(x)` are given as follows:
Line `f(x)` passes through points `(-4,0)` and `(-3,1)`.
Line `g(x)` passes through points `(-4,0)` and `(-3,-2)`.
Now, we have to determine the value of `k`.
Formula to find slope of a line is given by:(y2 - y1)/(x2 - x1)
Here, (x1, y1) = (-4, 0) and (x2, y2) = (-3, 1) for line f(x).
So, slope of line `f(x)` is given by:(1 - 0)/(-3 - (-4)) = 1
So, equation of line `f(x)` is given by:
y - y1 = m(x - x1) ⇒ y - 0 = 1(x - (-4)) ⇒ y = x + 4
Also, (x1, y1) = (-4, 0) and (x2, y2) = (-3, -2) for line g(x).
So, slope of line `g(x)` is given by:(-2 - 0)/(-3 - (-4)) = 2
So, equation of line `g(x)` is given by: y - y1 = m(x - x1) ⇒ y - 0 = 2(x - (-4)) ⇒ y = 2x + 8
Now, we can substitute the value of `k` and the equation of line `f(x)` to find the equation of line `g(x)`.
Let `k = 2`.
Then, `g(x) = k⋅f(x) = 2(x + 4) = 2x + 8`.
As we can see, this is the equation of line `g(x)` that passes through the points `(-4,0)` and `(-3,-2)`.
Therefore, the value of `k` is `2`. Hence, option (d) is the correct answer: `2`.

he yearly cost in dollars, y, at a video game arcade based on total game tokens purchased, x, is y = y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member and y = y equals StartFraction 1 Over 5 EndFraction x. x for a nonmember. Explain how the graph of a nonmember’s yearly cost will differ from the graph of a member’s yearly cost.
The key differences between the graphs of a nonmember's and a member's yearly cost lie in the slope, y-intercept, and the overall rate of increase in cost as the number of game tokens purchased increases.
The given equations represent the yearly cost in dollars for a member and a nonmember at a video game arcade based on the total game tokens purchased.
For a member:
y = (1/10)x + 60x + 60
For a nonmember:
y = (1/5)x
To understand how the graph of a nonmember's yearly cost differs from a member's yearly cost, let's analyze the equations and their characteristics.
Slopes:
The slope of the member's equation is (1/10), indicating that for every unit increase in the number of game tokens purchased (x), the yearly cost (y) for a member increases by 1/10 of a dollar. This means that the member's yearly cost increases at a slower rate compared to the nonmember's yearly cost.
The slope of the nonmember's equation is (1/5), which means that for every unit increase in the number of game tokens purchased, the yearly cost for a nonmember increases by 1/5 of a dollar. Therefore, the nonmember's yearly cost increases at a faster rate compared to the member's yearly cost.
y-intercepts:
For the member's equation, the y-intercept is 60, which represents the fixed cost component for being a member of the arcade. This means that even without purchasing any game tokens (x = 0), a member incurs a yearly cost of $60.
For the nonmember's equation, there is no additional fixed cost component. The y-intercept is 0, indicating that a nonmember has zero yearly cost if no game tokens are purchased (x = 0).
Overall cost:
The member's equation includes both a fixed cost component and a variable cost component, whereas the nonmember's equation only includes the variable cost component. This means that for any given number of game tokens purchased, the member's yearly cost will be higher than the nonmember's yearly cost.
Graphically, the member's equation will result in a line with a positive slope that intersects the y-axis at 60. The nonmember's equation will yield a line with a steeper positive slope that intersects the origin (0,0). The graph of the nonmember's yearly cost will rise more quickly than the graph of the member's yearly cost.

how do i do this I’ve been struggling for 45 minutes and i can’t seem to solve it…
Answer:
(a) start value = $45,000
(b) 4.6875 months exactly
======================================================
Explanation
Part (a)
I'll use x in place of t, and y in place of 'a'. The reason for this will be mentioned in part (b)
x = t = number of monthsy = a = account value in thousands of dollarsThe equation [tex]a = 45+75t-4t^2[/tex] turns into [tex]y = 45 + 75x - 4x^2[/tex] which rearranges to [tex]y = -4x^2+75x+45[/tex]
Let's plug in x = 0 so we can find the account value (variable y) at the very start.
[tex]y = -4x^2+75x+45\\\\y = -4*0^2+75*0+45\\\\y = 45\\\\[/tex]
The nice thing is any term involving x will go to zero, which leaves behind 45 at the end.
The initial value is $45,000. Recall that y is the value in thousands of dollars.
Think of it like saying 45*1000 = 45,000.
-------------------
Part (b)
The template for a general quadratic is [tex]y = ax^2+bx+c[/tex] which involves 'a', so that's why I swapped to x,y to avoid confusion.
That template is used to help complete the square to get a quadratic into vertex form.
Compare [tex]y = ax^2+bx+c[/tex] with [tex]y = -4x^2+75x+45[/tex] to find these values
a = -4b = 75c = 45Plug the first two items into the formula below
h = -b/(2a)
h = -75/(2*(-8))
h = 4.6875
This is the x coordinate of the vertex (h,k). It's the number of months it takes to reach the peak value.
-------------------
Extra info: If you plug x = 4.6875 back into the function, then you'll get y = 308.671875 which represents an account value of $308,671.88 (after rounding to the nearest penny). This is the investment's maximum value.

Trey made20000 in taxable income last year. suppose the income tax rate is 10% for the first $9500 plus 14% for the amount over $9500. How much must trey pay in income tax for last year?
Trey must pay $2420 in income tax for last year.
To solve this problemBased on the tax rates, we'll divide his taxable income into two halves.
The first portion is the minimal amount of Trey's taxable income between $9500 and $20,000 that is subject to a 10% tax rate. Consequently, the first component is $9500.
The second portion is the amount over $9500, which is $20,000 - $9500 = $10,500.
Now, let's calculate the tax for each portion:
Tax on the first portion (10% rate) = $9500 * 0.10 = $950.
Tax on the second portion (14% rate) = $10,500 * 0.14 = $1470.
We sum up the taxes on both portions to find Trey's total income tax:
Total income tax = Tax on the first portion + Tax on the second portion = $950 + $1470 = $2420.
So, Trey must pay $2420 in income tax for last year.

Half the members of a fishing tribe catch fish per day and half catch fish per day. A group of 10 members could build a boat for another tribe in 1 day and receive a payment of 45 fish for the boat. Part 2 a. Suppose the boat builders are drawn at random from the tribe. From the tribe's perspective, what is the expected cost of building the boat? enter your response here fish. (Enter your response as an integer.) Part 3 b. Now supposing that members are selected based on opportunity cost, the minimum cost that the boat could be built for is enter your response here fish. (Enter your response as an integer.)
a. From the tribe's perspective, the expected cost of building the boat when the boat builders are drawn at random from the tribe is 975 fish.
The number of members who catch fish per day is equal to the number of members who catch fish per day, which means that half of the tribe has a higher opportunity cost than the other half.
The expected cost can be calculated by multiplying the number of workers who catch fish per day by the daily cost of their fishing and adding this to the number of workers who catch fish per day multiplied by their daily cost of fishing.
b. When members are selected based on opportunity cost, the minimum cost that the boat could be built for is 450 fish. The cost of building the boat is equal to the opportunity cost of the members who build it, which is the value of their next best alternative.
Since the boat builders are drawn from the tribe with half the members catching fish per day and the other half catching fish per day, the minimum cost would be equal to the opportunity cost of the members who catch fish per day since their cost is higher than the other half of the tribe who catch fish per day. Therefore, the minimum cost would be 450 fish.
Half of the members catch fish per day, and half of the members catch fish per day. Hence the total cost of building the boat would be the summation of the costs of the members in the group.
For instance, the expected cost of building the boat can be calculated by multiplying the number of workers who catch fish per day by the daily cost of their fishing and adding this to the number of workers who catch fish per day multiplied by their daily cost of fishing.
In this case, the expected cost would be the cost of ten members who build the boat. Since each member is expected to contribute to the building of the boat, the total cost will be calculated as the summation of the cost of the members, which equals 975 fish.
Therefore, from the tribe's perspective, the expected cost of building the boat when the boat builders are drawn at random from the tribe is 975 fish.
The opportunity cost of building the boat is the value of the next best alternative.
When members are selected based on opportunity cost, the minimum cost that the boat could be built for is the opportunity cost of the members who build it. In this case, the members are drawn based on their fishing cost, meaning members with the lowest opportunity cost would be selected to build the boat.
Therefore, the minimum cost would be equal to the opportunity cost of the members who catch fish per day since their cost is higher than the other half of the tribe who catch fish per day. Hence the minimum cost of building the boat would be 450 fish.

Solve for the value of c.
(2c-3)°
97°
Answer:
the value of c is 50°.
Step-by-step explanation:
To solve for the value of c in the equation (2c - 3)° = 97°, we can start by isolating the term with c.
First, we add 3 to both sides of the equation to get rid of the -3:
(2c - 3)° + 3 = 97° + 3
Simplifying the equation, we have:
2c° = 100°
Next, we divide both sides of the equation by 2 to solve for c:
(2c°)/2 = (100°)/2
Simplifying further, we have:
c° = 50°

The true balance of the Ledger Control Account for January 2019 is $3,447,600 (debit).
To correct the Ledger Control Account for the month of January 2019, we need to analyze the given entries and make appropriate adjustments to arrive at the true balance.
Step 1: Analyzing the given entries
From the information provided, we can identify the following entries in the Ledger Control Account:
- Opening Balance (bf): $318,000 (debit)
- Purchases: $1,364,300 (debit)
- Cheques paid to creditors: $41,200 (credit)
- Purchases Returns: $31,000 (debit)
- Transfer from Sales Ledger: $31,000 (credit)
- Discount Received: $31,000 (credit)
- Closing Balance (c/d): $1,724,100 (debit)
Step 2: Adjusting the entries
To arrive at the true balance, we need to make adjustments for any errors or omissions in the given entries. Let's correct each entry:
- Opening Balance (bf) remains unchanged.
- Purchases: No adjustment needed.
- Cheques paid to creditors should be debited instead of credited. Adjust the entry to $41,200 (debit).
- Purchases Returns should be credited instead of debited. Adjust the entry to $31,000 (credit).
- Transfer from Sales Ledger should be debited instead of credited. Adjust the entry to $31,000 (debit).
- Discount Received should be debited instead of credited. Adjust the entry to $31,000 (debit).
- Closing Balance (c/d) remains unchanged.
Adjusted entries:
- Opening Balance (bf): $318,000 (debit)
- Purchases: $1,364,300 (debit)
- Cheques paid to creditors: $41,200 (debit)
- Purchases Returns: $31,000 (credit)
- Transfer from Sales Ledger: $31,000 (debit)
- Discount Received: $31,000 (debit)
- Closing Balance (c/d): $1,724,100 (debit)
Step 3: Calculating the true balance
To calculate the true balance, we need to sum up the debit and credit entries separately and find the difference:
Debit total: $318,000 + $1,364,300 + $41,200 + $31,000 + $31,000 + $1,724,100 = $3,509,600
Credit total: $31,000 + $31,000 = $62,000
True balance: Debit total - Credit total = $3,509,600 - $62,000 = $3,447,600 (debit)
Therefore, the true balance of the Ledger Control Account for January 2019 is $3,447,600 (debit).

Find m of angle ZLK if m of angle ZLK= x+86, m of angle MLK =130 degrees, and m of angle MLZ = x+ 66
We know that the sum of the angles in triangle MLK is 180 degrees. Therefore, we can find the measure of angle KLM as follows:
m∠MLK + m∠KLM + m∠LMK = 180
130 + m∠KLM + m∠LMZ = 180
We also know that angles ZLK and MLZ are vertical angles, so they are congruent. Therefore:
m∠ZLK = m∠MLZ
x + 86 = x + 66
86 = 66
This is a contradiction, so there is no value of x that satisfies the given conditions. Therefore, we cannot find the measure of angle ZLK.
What’s the answer for this one please show work!
Answer:
∠ MON = 51°
Step-by-step explanation:
∠ LON is composed of the 2 angles LOM and MON , that is
∠ LOM + ∠ MON = ∠ LON
42° + ∠ MON = 93° ( subtract 42° from both sides )
∠ MON = 51°
Answer:
<MON= 51°
Step-by-step explanation:
Look at the diagram and locate LON. You can see that LON is the angle of the complete line. Now LOM is given which is the angle of a part of the lines. So that means that to find MON we can minus LON with LOM.
<MON= <LON - <LOM
= 93-42
<MON= 51°

Discuss whether f(x)=x^2 increases or decreases when x>1
We can conclude that the function f(x) = x² is increasing when x > 1.The given function is f(x) = x². You need to determine whether this function is increasing or decreasing when x > 1.
To do this, we can find the derivative of the function and evaluate it for x > 1.If the derivative is positive, then the function is increasing, and if it is negative, then the function is decreasing.
The derivative of the function f(x) = x² is given by:f '(x) = 2x
We can see that the derivative is always positive when x > 1, as 2x is always positive for x > 0.Therefore, we can conclude that the function f(x) = x² is increasing when x > 1.

When we solve for theta, the result would be B. 20°
How to solve for thetaTo solve for theta, we would first represent the expression in the following way;
sinθ = cos(θ + 50)
sinθ =sin 90° - (50 + θ) cos (90 - θ)
sinθ = 90° - 50° - θ
Collect like terms
2θ = 90° - 50°
2θ = 40°
Divide both sides by 2
θ = 20°
Therefore the solution to theta is 20°

Answer:
B) 20°
Step-by-step explanation:
Given equation:
[tex]\sin \theta = \cos (\theta + 50^{\circ})[/tex]
To solve the given equation for θ, we can use a co-function identity.
Co-function identities are a set of trigonometric identities that relate the values of complementary angles.
[tex]\boxed{\begin{minipage}{5cm}\underline{Co-function Identities}\\\\$\sin \theta = \cos (90^{\circ}-\theta)$\\\\$\cos\theta = \sin(90^{\circ}-\theta)$\\\\\sin \theta=\cos\theta$,\;if\;$A+B=90^{\circ}$\\\end{minipage}}[/tex]
Using the cofunction identity sin θ = cos (90° - θ), we can say that:
[tex]\cos (90^{\circ} -\theta)=\cos (\theta + 50^{\circ})[/tex]
Therefore:
[tex]\begin{aligned} \theta + 50^{\circ} &= 90^{\circ} -\theta\\\theta + 50^{\circ} +\theta &= 90^{\circ} -\theta+\theta \\2 \theta+ 50^{\circ} -50^{\circ}&= 90^{\circ}\\2 \theta+ 50^{\circ} &= 90^{\circ} -50^{\circ}\\ 2 \theta&=40^{\circ}\\\theta&=20^{\circ}\end{aligned}[/tex]
Therefore, the value of θ is 20°.
