The expected value of Lucas going fishing is $26.56. This is calculated by multiplying the probability of each outcome (catching 0, 1, 2, or 3 walleye) by its corresponding payoff ($0, $0, $20, or $100) and adding the results.

To calculate the expected value of Lucas going fishing, we need to consider all possible outcomes and their respective probabilities

Lucas catches all 3 walleye Probability = (3/4) * (2/3) * (1/2) = 1/4 (since he has to catch each walleye in succession, with decreasing probabilities)

Value = $100

Lucas catches 2 walleye Probability = (3/4) * (2/3) * (1/2) * (1/4) * 3 = 9/32 (he has to catch 2 walleye in any order and then not catch the catfish in the remaining attempt)

Value = $20

Lucas catches 1 walleye Probability = (3/4) * (2/3) * (1/2) * (1/4) * (1/4) * 3 = 3/32 (he has to catch 1 walleye and then not catch the other two walleye and the catfish)

Value = $0

Lucas catches no walleye and no catfish Probability = (1/4) = 1/4 (since he has to catch the catfish)

Value = $0

Therefore, the expected value of Lucas going fishing is

E(X) = (1/4)$100 + (9/32)$20 + (3/32)$0 + (1/4)$0 = $26.56

So, on average, Lucas can expect to make $26.56 each time he goes fishing.

The probability of the die landing on a vowel is 1 in 5, or 20%.

In this game, the 20-sided die has the letters A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, R, S, T, and W. To calculate the probability of the die landing on a vowel, we need to identify the vowels present on the die and then determine the probability.

The vowels on this die are A, E, I, and O. There are 4 vowels out of the 20 possible outcomes, so the probability of landing on a vowel can be calculated by dividing the number of successful outcomes (vowels) by the total number of possible outcomes (20 sides).

Probability = (Number of Vowels) / (Total Sides)
Probability = 4 / 20

Now, simplify the fraction:

Probability = 1 / 5

The required answer is x = 14

To solve this problem, we can use algebraic equations. Let's start by representing the number of points that Aisha has with the variable "x".

According to the problem, we know that Carter has 7.5 more points than Aisha, so we can write:
Carter = x + 7.5
An algebraic equation or polynomial equation is an equation in which both sides are polynomials (see also system of polynomial equations). These are further classified by degree: linear equation for degree one. quadratic equation for degree two.

We also know that Jamila has 4.5 more points than Carter, which means:

Jamila = (x + 7.5) + 4.5

a variable (from Latin variabilis, "changeable") is a symbol that represents a mathematical object. A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.

Algebraic computations with variables as if they were explicit numbers solve a range of problems in a single computation. For example, the quadratic formula solves any quadratic equation by substituting the numeric values of the coefficients of that equation for the variables that represent them in the quadratic formula. In mathematical logic, a variable is either a symbol representing an unspecified term of the theory (a meta-variable), or a basic object of the theory that is manipulated without referring to its possible intuitive interpretation.
Finally, we know that Jamila has 26 points:

Jamila = 26

Now we can solve for x:

(x + 7.5) + 4.5 = 26

x + 12 = 26

x = 14

Therefore, Aisha has 14 points.

To show the work:

Aisha = x

Carter = x + 7.5

Jamila = (x + 7.5) + 4.5

Jamila = 26

(x + 7.5) + 4.5 = 26

x + 12 = 26

x = 14

Answer:

I believe it is

F = (9/5 x °C) + 32

Therefore, the equation of the function h(x) is: h(x) = -f(x) + 2.

A graph is a visual representation of data that shows the relationship between two or more variables. It consists of two axes - the x-axis (horizontal) and the y-axis (vertical) - that intersect at a point called the origin. Each axis is divided into equally spaced intervals or units that represent the range of values for each variable. Data points are plotted on the graph by identifying their corresponding x and y values and locating them on the appropriate axes. The points are then connected by a line or curve that represents the pattern or trend in the data. Graphs are commonly used in various fields such as mathematics, science, economics, and business to help analyze and interpret data. Some common types of graphs include line graphs, bar graphs, scatter plots, pie charts, and histograms.

Here,

Let's assume the equation of the original function f(x) is y = f(x). To obtain the function h(x), we first reflect the graph of f(x) over the x-axis. This means that for any point (x, y) on the graph of f(x), the corresponding point on the graph of h(x) will be (x, -y).

Next, we translate the reflected graph of f(x) two units up. This means that for any point (x, -y) on the reflected graph, the corresponding point on the graph of h(x) will be (x, -y + 2).

Therefore, the equation of the function h(x) is:

h(x) = -f(x) + 2

This equation reflects the graph of f(x) over the x-axis (by negating f(x)) and then translates the reflected graph 2 units up (by adding 2).

Larry could have about $139,827 in his IRA if he invests $250 at the beginning of each month and earns 3.5% interest compounded monthly, rounded to the nearest dollar

Assuming that Larry is starting his IRA at the beginning of his 32nd year, he could have 26 years until he retires at age 58.

Because he is investing $250 at the beginning of each month, that means he will be making an investment a complete of $3,000 consistent with year.

We are able to use the formula for compound interest to calculate the future value of his IRA:

[tex]FV = P * ((1 + r/n)^{(n*t)} - 1) / (r/n)[/tex]

Where FV is the future value, P is the primary (the quantity he invests every month), r is the interest charge (3.5%), n is the wide variety of times the interest is compounded consistent with year (12 for monthly), and t is the quantity of years.

Plugging within the numbers, we get:

[tex]FV = 250 * ((1 + 0.0.5/12)^{(12*26)} - 1) / (0.0.5/12) \approx $139,827[/tex]

If The area of a triangle is (27 + 13sqrt(2)) square feet. if the length of the base is (6 + sqrt(2)) feet, then the triangle's height is (27 - 13sqrt(2)) / 17 feet.

We are given the area A and the length of the base b. We can use this information to solve for the height h as follows:

A = (1/2)bh

2A = bh

h = (2A)/b

Substituting the given values, we get:

h = (2(27 + 13sqrt(2))) / (6 + sqrt(2))

We can simplify this expression by rationalizing the denominator as follows:

h = [(2(27 + 13sqrt(2))) / (6 + sqrt(2))] * [(6 - sqrt(2))/(6 - sqrt(2))]

h = [(54 - 26sqrt(2)) / (34)]

h = (27 - 13sqrt(2)) / 17

Ansley's cousin is 12 years old, and Ansley's age can be found by plugging in 12 for Cousin's age.

The problem tells us that Ansley's age is 5 years less than 3 times her cousin's age. We can write this as an equation:

Ansley's age = 3 × Cousin's age - 5

We also know that Ansley is 31 years old. So we can substitute 31 for Ansley's age in the equation:

31 = 3 × Cousin's age - 5

Now we solve for Cousin's age. First, we add 5 to both sides of the equation:

31 + 5 = 3 × Cousin's age

Simplifying:

36 = 3 × Cousin's age

Finally, we divide both sides by 3:

Cousin's age = 12

So Ansley's cousin is 12 years old, and Ansley's age can be found by plugging in 12 for Cousin's age in the expression we found earlier:

Ansley's age = 3 × Cousin's age - 5 = 3 × 12 - 5 = 31

The value of the double integral is zero.

The order of integration is dr dy, which means we first integrate with respect to r and then with respect to y.

Thus, we can write the integral as:

[tex]\int^0_{2\pi} \int^0_{1 + cos(a)}[/tex] r sin(θ) dr dy

Here, we have used the given limits of integration for r and y. Now, we integrate with respect to r first, treating y as a constant.

∫r sin(θ) dr = -cos(θ)r

We can substitute the limits of integration for r, which gives:

-cos(θ)(1+cos(a)) + cos(θ)(0)

Simplifying this expression, we get:

Now, we integrate this expression with respect to y, using the limits 0 to 2π for θ.

[tex]\int ^0_{2\pi}[/tex] -cos(θ)(1+cos(a)) dy

We can integrate this expression by treating cos(a) as a constant and using the formula for integrating cosine functions:
