Step-by-step explanation:

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.

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

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  

The equation of the circle in this problem is given as follows:

(x - 2)² + (y + 4)² = 36.

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

The coordinates of the center of the circle are given as follows:

(2, -4).

The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, hence, considering the horizontal line from the center to point (8, -4), it's measure is given as follows:

r = 6.

Thus the equation is:

(x - 2)² + (y + 4)² = 36.

Answer:

2f+2y+pd+z(d+2)

Step-by-step explanation:

If Brandon buys 2 gifts and the cost of each gift is f, then the cost of the 2 gifts is 2f.... 1

Also if Daniel buys d gifts, the cost of each gift is p, then the cost of d gifts will be "pd ".... 2

If Georgia buys 2 more gifts than Daniel, then the amount of gift bought by daniel will be d+2. If the cost of each gift is z, the cost of (d+2) gifts will be z(d+2) .... 3

If Mr. Jones also decides to buy gifts for his children and the cost of each gift is f, then the total cost of the gift he bought for his children is yf where y is the number of gifts he bought for his children.

The total amount paid by Mr. Jones will be expressed by the summing all the derived function as shown;

2f+dp+z(d+2)+yf

= 2f+yf+ dp+z(d+2)

= 2f+2y+dp+z(d+2)

Hence the algebraic expression for how much money Mr Jones should pay at the gift shop till if he also decides to buy gifts for his children and the cost of each gift is f is expressed as 2f+2y+dp+z(d+2)

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.

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.
