A stock price S is governed by dS = aSdt + bSdz
where z is a standardized Wiener process. Find the process that governs G(t) = S^1/2(t)
Answer:
G = S^1/2
Step-by-step explanation:
Solving the Equation
dS = aSdt + bSdz
First we Take S common from Right hand Side
dS = S(a dt + b dz)
Then we also take S Left Hand Side(LHS) from RHS
dS/S = a dt + b dz
So d = a dt + b dz
now we Take d Common from RHS
d = d(a t + b z)
So
d/d = a t + b z
1 = a t + b z
So, t = (1-b z) / a
Now substitute value of t in equation G(t) = S^1/2(t)
we have
G{(1- b z)/a} = S^1/2 {(1- b z)/a}
(1- b z)/a) from both sides cancels out each other
So we have G = S^1/2

Identify the correlation you would expect to see between the average amount of snowfall (inches) and the number of school closings.
Answer:
Simple Linear Regression Correlation
Step-by-step explanation:
When it snows normally the schools continue .But constant snowing affects the schools continuity. As more and more snow falls more schools are closed.
There may be a situation where all the schools are closed at a certain temperature.
So it is a simple linear regression correlation because in it there are two variables and one variable is dependent on the other. In this example the schools are dependent on the average snowfall.
If there's a snow blizzard or extreme weather all the schools are definitely closed .
It can be represented by a graph.

Elias completely covered a square canvas using 77.8 in.² of fabric without any overlap. Which measurement is closest to the side length of this canvas in inches? 8 in. 9 in. 19 in. 39 in. say the number and tell me why you got it.
Answer:
9 inStep-by-step explanation:
Since the square canvas was completely covered using 77.8 in.² of fabric without any overlap, to get the side length of the canvas, we will use the formula for calculating the area of a square.
Area of a square = Length * Length
A = L*L
A = L²
Given the Area of the area of the square canvas as 77.8 in², on substituting this values into the formula to get L we have;
77.8 = L²
Take the square root of both sides
√77.8 = √L²
L = √77.8
L = 8.82 in
L ≈ 9inches
The length 8.82in gotten was approximated to 9in because the first value after the decimal point is greater that 4 and once we have such case 1 will be added to the value before the decimal point i.e 8 to make it 9.
Hence measurement that is closest to the side length of this canvas in inches is 9inches.

3. Michael goes on a Camel Safari in Africa.
He travels 5 km north, then 4 km east, and
then 5 km south.
Distance:
Displacement:
Answers:
Distance = 14 km
Displacement = 4 km east
==============================================
Explanation:
The total distance is simply the sum of the values given. So he traveled a total of 5+4+5 = 9+5 = 14 km overall.
----------------------
The displacement is where a drawing may come in handy. Draw an xy axis. Place point A at the origin (0,0). This is where Michael starts his trip. Then move up to (0,5) to indicate he goes 5 km north. Call this point B.
Afterward, mark point C at (4,5) to show he has gone 4 km east. Finally, point D is at (4,0) because he went 5 km south
The displacement is only concerned with two points: The start and end point. Nothing else matters. We started at A(0,0) and ended at D(4,0). So we've gone 4 km east overall. The direction is important when it comes to displacement. Simply saying "4 km" isn't enough. So in a sense, we could take a shortcut from A directly to D, bypassing the other points B and C.

At the grocery store, Mr. Abroms saw eggplants that cost $1.79 each, apples that cost $0.59 each, bags of spinach that cost $2.55 each, and cartons of orange juice that cost $3.89 each. Which of these statements below are true? Choose the three correct answers.
Answer:
Option 1, 3 and 5 are correct
Step-by-step explanation:
Given
Eggplants = $1.79 each
Apples = $0.59 each,
Bags of spinach = $2.55 each
Cartons of orange juice = $3.89 each
Required
Select three true statements
To do this, we'll check the options one after the other
1. 4 eggplants cost about $0.50 less than 3 bags of spinach
First, we need to calculate the cost of 4 eggplants
4 Eggplants = 4 * 1 Eggplants
4 Eggplants = 4 * $1.79
4 Eggplants = $7.16
Next, we calculate the cost of 3 bags of Spinach
3 bags of Spinach = 3 * 1 bag of Spinach
3 bags of Spinach = 3 * $2.55
3 bags of Spinach = $7.65
Determine the difference
Difference = |Eggplants - Bags of Spinach|
Difference = |$7.16 - $7.65|
Difference = |-$0.49|
Difference = $0.49
This statement is true because $0.49 approximates to $0.50
2. Total cost of 4 apples and 2 eggplants $0.50 is more than $6.00
First, we need to calculate the cost of 4 apples
4 Apples = 4 * 1 Apples
4 Apples = 4 * $0.59
4 Apples = $2.36
Next, we calculate the cost of 2 Eggplants
2 Eggplants = 2 * 1 Eggplant
2 Eggplants = 2 * $1.79
2 Eggplants = $3.58
Add this two results together
Total = 4 Apples + 2 Eggplants
Total = $2.36 + $3.58
Total = $5.94
This statement is false because the sum is less than $6.00
3. Total cost of 4 eggplants, 4 apples and 1 carton of orange juice is $13.41
In (1) & (2) above
4 Eggplants = $7.16
4 Apples = $2.36
1 carton of orange juice = $3.89
Add the above together
Total = $7.16 + $2.36 + $3.89
Total = $13.41
This statement is true because the sum is $13.41
4. Total cost of 5 eggplants is greater than cost of 4 bags of spinach
First, we need to calculate the cost of 5 eggplants
5 Eggplants = 5 * 1 Eggplants
5 Eggplants = 5 * $1.79
5 Eggplants = $8.95
Next, we calculate the cost of 4 bags of Spinach
4 bags of Spinach = 4 * 1 bag of Spinach
4 bags of Spinach = 4 * $2.55
4 bags of Spinach = $10.20
This statement is false because 4 Eggplants costs less than $ bags of spinach
5. Total cost of 2 eggplants, 2 apples and 2 cartons of orange juice is $9.99 more than cost of 1 bag of spinach
From (2) above
2 Eggplants = $3.58
Next, we need to calculate the cost of 2 apples
2 Apples = 2 * 1 Apples
2 Apples = 2 * $0.59
2 Apples = $1.18
Next, we need to calculate the cost of 2 cartons of orange juice
2 Cartons = 2 * 1 Carton
2 Apples = 2 * $3.89
2 Apples = $7.78
Sum these up
Total = $3.58 + $1.18 + $7.78
Total = $12.54
1 Bag of spinach = $2.55 each
Subtract 1 Bag of spinach from the $12.54
Difference = $12.54 - $2.55
Difference = $9.99
This statement is true because the difference is $9.99

What is the slope of the line? y + 5=2(x+1)
Answer:
The slope of the line given by the equation is two.
Step-by-step explanation:
We are given the equation:
[tex]y+5=2(x+1)[/tex]
Notice that the equation is written in point-slope form. That is:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope.
From our given equation, we can see that m = 2.
Therefore, the slope of the given line is 2.
Answer:
2
Step-by-step explanation:
Put the line into slope intercept form:
y + 5 = 2(x+1)
Distribute the 2
y + 5 = 2x + 2
Isolate y to put into y = mx + b form
y = 2x - 3
So, the slope is 2 because it is the coefficient to x.

Mr. Thoro ordered 5 chicken shawarma wraps and 4 orders of spiced potatoes for a total bill of $74.91. What is the cost of a chicken shawarma wrap? What is the cost of one order of spiced potatoes? If x denotes the cost of a chicken shawarma wrap and y denotes the cost of an order of spiced potatoes, what are the equations needed to solve this problem?
Answer:
What is the cost of a chicken shawarma wrap?
$10.99
What is the cost of one order of spiced potatoes?
$4.99
If x denotes the cost of a chicken shawarma wrap and y denotes the cost of an order of spiced potatoes, what are the equations needed to solve this problem?
3x + 2y = $42.95..........Eq 1
5x + 4y = $74.91..........Eq 2
Step-by-step explanation:
Cost of a chicken sharwarma wrap = a
Cost of an order of spiced potatoes = b
Ms. Ironperson ordered 3 chicken shawarma wraps and 2 orders of spiced potatoes for a total bill of $42.95.
3x + 2y = $42.95 .............Equation 1
Mr. Thoro ordered 5 chicken shawarma wraps and 4 orders of spiced potatoes for a total bill of $74.91.
5x + 4y = $74.91 ................Equation 2
So we have:
3x + 2y = $42.95..........Eq 1
5x + 4y = $74.91..........Eq 2
We use Elimination method
Multiply Equation 1 by coefficient of y in Equation 2
Equation 2 by coefficient of y in Equation 1
3x + 2t= $42.95 .............Equation 1 × 4
5x + 4y = $74.91 ................Equation 2 × 2
12x + 8y = 171.80..............Equation 3
10x + 8y = 149.82..............Equation 4
Subtract Equation 3 from Equation 4
2x = 21.98
x = 21.98/2
x = 10.99
Therefore, x = Cost of Chicken sharwarma wrap = $10.99
Subtitute 10.99 for 9in Equation 1
3x + 2y = $42.95 .............Equation 1
3(10.99) + 2y = 42.95
32.97 + 2y = 42.95
2y = 42.95 - 32.97
2y = 9.98
y = 9.98/2
y = 4.99
y = Cost of an order of spiced potatoes = $4.99
Hence,
The cost of a chicken sharwarma wrap = $10.99
The cost of an order of spiced potatoes = $4.99

5x-3x+x+10-y+2y
3x+10+y
Answer:
3x+y+10
Step-by-step explanation:
Since we are trying to combine like terms, we must rearrange the terms, and group the terms with an x, together, a y together, and the constants. Doing that, we get
(5x+x-3x)+(2y-y)+10
Now we start with the x terms, and we add 5x+x=6x and then 6x-3x= 3x, so you have 3x, and now for the y terms
we have 2y-y=y and lastly we have a ten, so adding them together, we get
3x+y+10
You have two recipes that together use a pound of butter. One recipe takes a 1/4 pound more than the other one. How much butter does each recipe use?
Answer:
First recipe needs = 3/8
Second recipe needs = 5/8
Step-by-step explanation:
Given:
Two recipes needs butter = 1 pound
One recipe needs 1/4 pound more
Find:
Each recipe needs butter
Computation:
Assume;
First recipe needs = x
Second recipe needs = x + (1/4)
Two recipes needs butter = First recipe needs + Second recipe needs
x + x + (1/4) = 1
2 x = 1 - (1/4)
2 x = 3/4
x = 3/8 pound
First recipe needs = 3/8
Second recipe needs = x + (1/4) = (3/8) + (1/4) = 5/8
Second recipe needs = 5/8
