Chadwick bought 50 shares of Chipotle stock on Nov 1, 2016 for $396.33 share. He sold the shares four years later, with the per closing price for that day of $778.38. A) What did Chadwick pay for all of the shares in 2016? B) What was the closing value of all of the shares four years later? C) How much money did he gain / l * o * s with this stock? D) What is his rate of return on his shares when he sold them?
Answer:
Step-by-step explanation:
Given the following :
Number of shares purchased (2016) = 50
Purchase price of shares $396.33 per share
Closing price per share four years later = $778.38
A) What did Chadwick pay for all of the shares in 2016?
Purchase price per share × number of shares.
$396.33 × 50 = $19,816.50
B) What was the closing value of all of the shares four years later?
Closing price per share × number of ahaf
=$778.38 × 50
= $38,919
C.) Profit on stock :
$(38,919 - 19,816.50)
= $19,102.5
D) What is his rate of return on his shares when he sold them?
(Current Purchase - initial value) /current price
(778.3 - 396.33) / 396.33
= (381.97 / 396.33) 100%
= 0.9637675
=
76%

Given the function f(x,y) = 4xy^2 - x^2y^2 - xy^3 (a) Find and classify all the critical points (b) Find the absolute maximum and minimum values of f(x,y) on D, where D is the closed triangular region in the xy plane with vertices (0,0) (0,6) and (6,0) .
The absolute maximum value of f(x, y) on D is 0, and the absolute minimum value is -64.
(a) To find the critical points of the function f(x, y) = 4xy^2 - x^2y^2 - xy^3, we need to find the values of x and y where the partial derivatives with respect to x and y are equal to zero.
Taking the partial derivative with respect to x:
∂f/∂x = 4y^2 - 2xy^2 - y^3
Taking the partial derivative with respect to y:
∂f/∂y = 8xy - 2x^2y - 3xy^2
Setting both partial derivatives equal to zero and solving the resulting system of equations will give us the critical points.
4y^2 - 2xy^2 - y^3 = 0 ...(1)
8xy - 2x^2y - 3xy^2 = 0 ...(2)
From equation (1), we can factor out y^2:
y^2(4 - 2x - y) = 0
This gives us two possibilities: y = 0 or 4 - 2x - y = 0, which simplifies to y = 4 - 2x.
Substituting y = 0 into equation (2), we get:
8xy = 0
This implies that either x = 0 or y = 0.
So, we have three possible cases for the critical points:
Case 1: y = 0, which implies x = 0 from equation (2).
Case 2: x = 0, which implies y = 4 from the equation y = 4 - 2x.
Case 3: Solving the equations 4 - 2x - y = 0 and 8xy - 2x^2y - 3xy^2 = 0 simultaneously will give us additional critical points.
(b) To find the absolute maximum and minimum values of f(x, y) on the closed triangular region D, we need to evaluate the function at the vertices of the triangle and at the critical points found in part (a).
The vertices of the triangle D are (0, 0), (0, 6), and (6, 0).
Evaluate f(x, y) at the vertices:
f(0, 0) = 0
f(0, 6) = 0 - 0 - 0 = 0
f(6, 0) = 4(6)(0)^2 - (6)^2(0)^2 - (6)(0)^3 = 0
Evaluate f(x, y) at the critical points:
f(0, 0) = 0
f(0, 4) = 4(0)(4)^2 - (0)^2(4)^2 - (0)(4)^3 = -64
f(2, 2) = 4(2)(2)^2 - (2)^2(2)^2 - (2)(2)^3 = 8 - 8 - 16 = -16
Therefore, the absolute maximum value of f(x, y) on D is 0, and the absolute minimum value is -64.

U and V are mutually exclusive events. P(U) = 0.26; P(V) = 0.37. Find:
a. P(U AND V) =
b. P(U|V) =
c. P(U OR V) =
U and V are mutually exclusive events. P(U) = 0.26; P(V) = 0.37. So,
a. P(U AND V) = 0
b. P(U|V) = 0
c. P(U OR V) = P(U) + P(V)
U and V cannot happen at the same time since they are mutually exclusive events. Therefore, the probability of their intersection, P(U AND V), is equal to 0.
Comparably, the conditional probability P(U|V) denotes the likelihood that event U will take place in the event that event V has already happened. U, however, is not possible if V has already happened because U and V are mutually exclusive. Consequently, P(U|V) likewise equals 0.
To find the probability of the union of U and V, P(U OR V), we add the individual probabilities of U and V because they are mutually exclusive. Therefore, P(U OR V) = P(U) + P(V) = 0.26 + 0.37 = 0.63.

The weights of grapefruits of a certain variety vary according to a roughly Normal distribution with a mean of 1 pound and a standard deviation of 0.12 pounds. What is the probability that a randomly selected grapefruit weights more than 1.25 pounds?
а. 0.019
b. 0.016
C. 0.316
d. 0.401
The probability that a randomly selected grapefruit weighs more than 1.25 pounds is approximately 0.019.
To find the probability that a randomly selected grapefruit weighs more than 1.25 pounds, we need to calculate the area under the normal distribution curve to the right of 1.25 pounds.
First, we calculate the z-score using the formula:
z = (x - μ) / σ,
where
x is the value we're interested in,
μ is the mean, and
σ is the standard deviation.
In this case, x = 1.25, μ = 1, and σ = 0.12.
z = (1.25 - 1) / 0.12 = 2.08
Next, we look up the corresponding area under the standard normal distribution curve for a z-score of 2.08. Using a standard normal distribution table or calculator, we find that the area to the right of 2.08 is approximately 0.019.

A foreign exchange student from Mexico would like to buy pastries for her host family. She
finds a special deal “6 pastries for $17.94,” that she would like to purchase for her family.
However, her host family consists of 4 people. If she wants to purchase 4 pastries for her
family members at that special rate, what would the cost be of these pastries in her currency
of Mexican Pesos? (Currency conversion rate is 1 U.S. Dollar = 19.265 Mexican Pesos).
Answer:
11.96 USD = 230.41 MXN
11.96 MXN = .62 USD
Step-by-step explanation:
6 pastries for 17.94 = 1 pastry for 2.99 = 4 pastry for 11.96
11.96 USD = 230.41 MXN
11.96 MXN = .62 USD

Sometimes by labeling the numbers in a statement, you can make a statement true that would normally be false. For example, the statement 12+2=3 could be made true by labeling the number as follows: 12 inches + 2 feet = 3 feet By labeling the numbers in the statement 9 + 6 = 3, make the statement true.
Step-by-step explanation:
Yes this is actually correct, labelling numbers gives it a meaning, and also makes it understandable to whoever is reading or solving a problem associated with the number
12+2=3 ordinarily would be false because
12+2=14
but when a label is attached
that is 12 inches + 2 feet= 3 feet
12 inches is the same as 1 foot
so 1foot+2feet= 3 feet
9 + 6 = 3 ordinarily is false as 9 + 6 = 15
but
√9feet + 6feet = 3yard
3feet + 6feet = 3yard
