Before the price change, the optimal consumption choice (A) is determined by equalizing the marginal utilities of x and y.
Using the utility function U(x, y) = xy, and considering prices of Px = 1 and Py = 2, along with an income of 40, we find that the utility equalization condition leads to y = x/2.
With the budget constraint of x + 2y = 40, we solve for x = 20 and y = 10, giving the optimal consumption choice (20, 10) labeled as point A on the graph.
After the price change, with the price of y falling to 1, the consumer aims to maintain the same utility level. Setting MUX/Px = MUY/Py, we find x = y, and using the budget constraint x + y = 40, we get x = y = 20, resulting in the optimal consumption choice (20, 20) labeled as point B.
The substitution effect is illustrated by a movement from A to B along the budget constraint. The new optimal consumption choice (C) after the price change is determined by the new budget constraint x + y = 40, where x = 30 and y = 10, labeled as point C on the graph.
The income effect is depicted by the parallel shift of the budget constraint line outward from the origin.

If the probability of surviving the zombie apocalypse for 1 year is 20% a. what are the odds of surviving (explain)? (1 pt) b. What are the odds of not surviving (explain)? (1 pt) c. If I bet $25 on you to survive, and you do, how much would you pay based on the odds? (1 pt)
a) The odds of surviving is 1/4
b) The odds of not surviving is 4.
c) You would receive a payout of $6.25 if you bet $25 on surviving and you successfully survive the zombie apocalypse.
a) The odds of surviving the zombie apocalypse can be calculated by taking the probability of survival (20%) and dividing it by the probability of not surviving
100% - 20% = 80%
So the odds of surviving would be,
20%/80% = 1/4
This means that for every one chance of surviving, there are four chances of not surviving.
b) The odds of not surviving the zombie apocalypse can be calculated by taking the probability of not surviving (80%) and dividing it by the probability of survival (20%).
So the odds of not surviving would be
80%/20% = 4/1
This means that for every four chances of not surviving, there is one chance of surviving.
c) If you bet $25 on surviving and you do survive, based on the odds of 1/4, you would win the bet. The payout can be calculated by multiplying the bet amount by the odds of surviving.
So the payout would be
$25 * 1/4 = $6.25
Therefore, based on the odds, you would receive a payout of $6.25 if you bet $25 on surviving and you successfully survive the zombie apocalypse.

Given a smooth function / such that f(-0.2) = -0.91736, f(0) = -1 and f(0.2) = -1.04277. Using the 2-point forward difference formula to calculate an approximated value of f'(0) with h = 0.2, we obtain: f'(0) = -0.21385 f'(0) = -1.802 f'(o) -2.87073 f'(0) = -0.9802
The approximated value of f'(0) using the 2-point forward difference formula with h = 0.2 is -0.21385. So, first option is the correct answer.
To calculate an approximate value of f'(0) using the 2-point forward difference formula with h = 0.2, we can use the given function values:
f(-0.2) = -0.91736
f(0) = -1
f(0.2) = -1.04277

How many different ways can you write a fraction that has a numerator of 2 as a sum of fractions? Explain.
Answer:
Step-by-step explanation:
1/5 + 1/5 = 2/5
1/7 + 1/7 = 2/7
1/3 + 1/3 = 2/3
There are an infinite number of these fractions. They must be 1 and 1 in the numerator, and the denominator must be relatively prime to 2. The examples I have picked are prime in the denominator, but the rule is not without many exceptions. For example
1/9 + 1/9 = 2/9
I don't think you can pick an even denominator because it will reduce when put with two. Oh wait 2/18 + 2/18 = 4/18 = 2/9 But these could be reduced before adding. Still, it might count. It depends on who is marking the question.
What about an odd and even denominator?

Answer:B
Step-by-step explanation:
what is the probability rule for deciding whether events a and b are independent
Events A and B are considered independent if and only if the probability of their intersection (P(A ∩ B)) is equal to the product of their individual probabilities (P(A) * P(B)).
Independence: Two events A and B are independent if the occurrence or non-occurrence of one event does not affect the probability of the other event.
Joint Probability: The joint probability P(A ∩ B) represents the probability of both events A and B occurring together.
Multiplication Rule: According to the multiplication rule for independent events, if events A and B are independent, the probability of their intersection is equal to the product of their individual probabilities.
P(A ∩ B) = P(A) * P(B)
Interpretation: If the equation holds true, events A and B are considered independent since the probability of their intersection can be determined solely by multiplying their individual probabilities.
Dependence: If the equation does not hold true, it implies that the occurrence of one event affects the probability of the other event, indicating dependence between the two events.
In summary, the multiplication rule for independent events states that events A and B are independent if and only if P(A ∩ B) = P(A) * P(B).

what is the equation of a line that is parallel to the line 2x 5y = 10 and passes through the point (–5, 1)? check all that apply.
A. y = −x − 1
B. 2x 5y = −5
C. y = −x − 3
D. 2x 5y = −15 y
E. − 1= −(x 5)
The equation of a line that is parallel to the line 2x - 5y = 10 and passes through the point (-5, 1) is B. 2x - 5y = -5.
To find the equation of a line that is parallel to the line 2x - 5y = 10, we need to determine the slope of the given line first. The equation is in the form of Ax + By = C, where A = 2, B = -5, and C = 10.
To find the slope, we can rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope.
2x - 5y = 10
-5y = -2x + 10
y = (2/5)x - 2
From this equation, we can see that the slope of the given line is 2/5.
A line that is parallel to this line will have the same slope. Therefore, the equation of the parallel line can be determined using the point-slope form (y - y1 = m(x - x1)), where (x1, y1) represents the coordinates of the given point (-5, 1).
Using the slope of 2/5 and the point (-5, 1), we can now check the options to see which ones satisfy the conditions:
A. y = -x - 1: This equation has a slope of -1, not 2/5. It is not parallel to the given line.
B. 2x - 5y = -5: This equation has the same slope of 2/5 and passes through the point (-5, 1). It satisfies the conditions and is parallel to the given line.
C. y = -x - 3: This equation has a slope of -1, not 2/5. It is not parallel to the given line.
D. 2x - 5y = -15y: This equation has a slope of 2/20, which simplifies to 1/10. It is not parallel to the given line.
E. -1 = -(x - 5): This equation does not represent a line. It is not a valid option.
Therefore, the equation of a line that is parallel to the line 2x - 5y = 10 and passes through the point (-5, 1) is B. 2x - 5y = -5.

Using the inverse matrix, the solution to the system of equations is X₁ = -7/25 and X₂ = -2/25.
To solve the system of equations using the inverse matrix, we can represent the equations in matrix form as AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix.
The system of equations can be written as:
Equation 1: -3X₁ + 2X₂ = -3
Equation 2: 3X₁ + 5X₂ = 1
Equation 3: 3X₁ - 2X₂ = 4
Equation 4: -4X₁ + 3X₂ = -5

Answer:
7.2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Distance "D" = rate × time
or d = r × t.
Tad and his buddies drove to the orange bowl(while going) -50mph
Tad and his buddies while returning from a trip -75mph
Total round trip = 12 hours
Distance while going = 50 x t
Distance while returning = 75 (12 - t)
50t = 75(12 -t)
50t = 900 -75t
50t + 75t = 900
125t = 900
t = 900/125
t= 7.2
The total number of hours it takes Tad and his buddies to drive to the orange bowl is 7.2 hours.

The sheet of metal has dimensions 56 cm by 33 cm. It sis melted down
and recast into discs of the same thickness and radius 7 cm. How many
disces will be cast ?
Answer:
12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12

Raymond bought a car for $40,000. He took a 20,000 loan from a bank at an interest rate of 15% per year for a 5 - year period. What is the total amount ( interest and loan) that he would have to pay rhe bank at the end of 5 years
Answer:
$35,000
Step-by-step explanation:
The amount that would be repaid = amount borrowed + interest earned on loan
interest earned on deposit can be determined by determining the simple interest
Simple interest = principal x time x interest rate
principal = the amount deposited = 20,000
Time = the duration of the deposit =5
interest rate = the percentage on deposit that would be earned = 15
20,000 x 5 x 0.15 = $15,000
total = 20,000 + 15,000 = $35,000
Find the work done by the force field F in moving an object from A to B. F(x y) = 6y3/2 i + 9x x square root y j A{ 1, 1), B(3, 4)
The integrate is W = 12 ∫[0 to 1] (1 + 3t)^(3/2) dt + 27 ∫[0 to 1] (1 + 2t) √(1 + 3t) dt.
To find the work done by the force field F in moving an object from point A to point B, we can use the line integral of the force field along the path connecting A and B. The line integral is given by the formula:
W = ∫[C] F · dr
where C represents the curve connecting points A and B, F is the force field, dr is the differential displacement vector along the curve, and · denotes the dot product.
First, let's calculate the differential displacement vector dr. Since we are moving from point A(1, 1) to point B(3, 4), the differential displacement vector dr can be expressed as:
dr = dx i + dy j
Now, let's determine the curve C connecting A and B. The curve can be parametrized as follows:
x(t) = 1 + 2t
y(t) = 1 + 3t
where t varies from 0 to 1.
Differentiating these parametric equations, we obtain:
dx = 2 dt
dy = 3 dt
Substituting these values into the differential displacement vector dr, we have:
dr = 2 dt i + 3 dt j
Next, let's calculate the force field F at each point along the curve C. Given that F(x, y) = 6y^(3/2) i + 9x √y j, we can substitute the parametric equations for x and y into F:
F = 6(1 + 3t)^(3/2) i + 9(1 + 2t) √(1 + 3t) j
Now, let's evaluate the line integral by substituting the values of F and dr into the integral expression:
W = ∫[0 to 1] (6(1 + 3t)^(3/2) i + 9(1 + 2t) √(1 + 3t) j) · (2 dt i + 3 dt j)
Expanding the dot product, we have:
W = ∫[0 to 1] (12(1 + 3t)^(3/2) dt + 27(1 + 2t) √(1 + 3t) dt)
Now, we can simplify and integrate each term separately:
W = 12 ∫[0 to 1] (1 + 3t)^(3/2) dt + 27 ∫[0 to 1] (1 + 2t) √(1 + 3t) dt
To evaluate these integrals, we can use appropriate substitution or integration techniques. After integrating both terms, we will have the value of the work done by the force field F in moving the object from A to B along the curve C.
