To find the expected value of the largest of the three claims, we will first need to understand the probability density function (pdf) of the maximum of the three independent random variables.   The formula is = ∫x * 3 * F(x)^2 * f(x) dx

Let's denote the common density function as f(x), and the cumulative distribution function (CDF) as F(x), where x is the amount of a claim in thousands.
Step 1: Find the CDF of the maximum of three claims
Since the claims are independent random variables, the CDF of the maximum of three claims (denoted as M) is given by the product of the individual CDFs: F_M(x) = F(x)^3.
Step 2: Find the pdf of the maximum of three claims
To obtain the pdf of M, we need to differentiate the CDF with respect to x. Let's denote the pdf of M as f_M(x):
f_M(x) = d(F_M(x))/dx = d(F(x)^3)/dx = 3 * F(x)^2 * f(x).
Step 3: Compute the expected value of the largest claim
The expected value of the largest claim (denoted as E[M]) is given by the integral of the product of the pdf and the variable x over the support of the distribution:
E[M] = ∫x * f_M(x) dx
= ∫x * 3 * F(x)^2 * f(x) dx
To evaluate this integral, you would need the specific form of the common density function f(x) and the cumulative distribution function F(x). However, the general formula for the expected value of the largest claim is provided above.

There were approximately 304,657,600 Americans in July 2009.

To find out how many Americans were there in July 2009, we'll use the given data in the student question:
Initial population (July 2008): 302,000,000 people
Growth rate (2008): 0.88%
Step 1: Convert the growth rate percentage to a decimal.
0.88% = 0.0088
Step 2: Calculate the population increase for 2009.
Increase = Initial population × Growth rate
Increase = 302,000,000 × 0.0088
Increase ≈ 2,657,600 people
Step 3: Add the population increase to the initial population to get the population in July 2009.
Population (July 2009) = Initial population + Increase
Population (July 2009) ≈ 302,000,000 + 2,657,600

Answer:

d=91

Step-by-step explanation:

Answer:   d=91

Step-by-step explanation:

First thing first, you have to use the distributive property. Distribute the 8 to the d-87.

(8*d) - (8*87) = 32  =    8d - 696= 32  

Next, you have to add 696 to both sides of the equation:

8d-696 +696= 32+696  =  8d= 728

Last step is to divide both sides by 8:

8d/8 = 728/8 =  

d= 91

We can check this by plugging the number 91 to the variable d in the equation:

(8*91) - (8 *87) = 32    =  728 - 696= 32

The volume of the cylinder is 18.0864 cubic cm and the surface area of the cylinder is 39.1872 square cm.

What is a cylinder?

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry.

We are given that the radius of the cylinder is 1.2 cm and the height is 4 cm.

So,

⇒ Volume = π[tex]r^{2}[/tex]h

⇒ Volume = π * [tex](1.2)^{2}[/tex] * 4

⇒ Volume = 3.14 * 5.76

⇒ Volume = 18.0864 cubic cm

Similarly,

⇒ Total surface area = 2πrh + 2π[tex]r^{2}[/tex]

⇒ Total surface area = 2π * 1.2 * 4 + 2π[tex](1.2)^{2}[/tex]

⇒ Total surface area = 2π * 4.8 + 2π * 1.44

⇒ Total surface area = 2π * (4.8 + 1.44)

⇒ Total surface area = 2 * 3.14 * 6.24

⇒ Total surface area = 39.1872 square cm

The following descriptions of the function passing through (0,7) and (4,4) are true:

The slope of the function is -3/4 and the y-intercept is 7.

The function is linear and continuous.

y=-3/4x + 7 represents this function.

y = -4/3x + 9 represents this function.

In mathematics, a function is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output. A function is often represented by a mathematical expression, formula or graph. Functions can be described using different notations, such as f(x), y = f(x), or y = g(u,v), and they can take various forms, such as linear, quadratic, polynomial, exponential, logarithmic, trigonometric, and many others.

Here,

To determine which descriptions of the function are true, we need to use the information given about the two points (0,7) and (4,4) to find the slope and y-intercept of the linear function that passes through them. Using the formula for the slope of a line:

slope = (4 - 7) / (4 - 0) = -3/4

So the slope of the function is -3/4.

To find the y-intercept, we can use the point-slope form of the equation of a line, which is y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is a point on the line. We can use either of the two points given:

y - 7 = (-3/4)(x - 0)

y - 7 = (-3/4)x

y = (-3/4)x + 7

So the y-intercept of the function is 7.

Using this information, we can now evaluate the given descriptions of the function:

y = 7x - 3/4: This represents the function, but the slope is incorrect (should be -3/4).

The function is decreasing: This is not true, since the slope is negative but less than -1.

y=-3/4x + 7: This represents the function, and the slope and y-intercept are both correct.

The slope of the function is -4/3 and the y-intercept is 9: This is not true, since the slope is -3/4 and the y-intercept is 7.

The function is increasing: This is not true, since the slope is negative.

The slope of the function is -3/4 and the y-intercept is 7: This is true, as shown by the calculations above.

y = -4/3x + 9: This represents a different function with a different slope and y-intercept.

The function is linear and continuous: This is true, since the function is a linear equation and is continuous over its domain.

The function is linear and discrete: This is not true, since the function is continuous over its domain.

The probability of not getting a clay pot or a cactus when randomly picking a plant and a pot from a selection of 4 plants and 4 pots is 0.75 or 75%.

There are a total of 4 x 4 = 16 possible outcomes when randomly picking a plant and a pot. Out of these, we need to count the number of outcomes where we don't get a clay pot or a cactus.

Let's start by counting the number of outcomes where we get a clay pot or a cactus. There are 4 possible outcomes for the plant (cactus or one of the three other plants) and 1 possible outcome for the pot (clay pot). So there are 4 x 1 = 4 outcomes where we get a cactus or a clay pot.

Therefore, the number of outcomes where we don't get a cactus or a clay pot is:

16 - 4 = 12

So the probability of getting a plant and a pot where neither the plant is a cactus nor the pot is a clay pot is:

P = number of outcomes where we don't get a cactus or a clay pot / total number of outcomes

= 12 / 16

= 0.75

Therefore, the probability of not getting a clay pot or a cactus is 0.75 or 75%.

Answer: The cost of the banana is $0.05.

This is an exercise in elementary algebra, which is a branch of mathematics that focuses on the study of the fundamental operations and properties of numbers and algebraic expressions. In particular, in elementary algebra you learn to solve problems by manipulating algebraic expressions and applying basic algebraic rules and procedures.

One of the fundamental skills of elementary algebra is solving systems of linear equations with two variables. Such a system is a set of two or more equations involving two or more variables. In the case of a system of two linear equations with two variables, the solution of the system consists in finding the numerical values of the two variables that satisfy both equations.

The substitution technique is one of the main tools used to solve systems of linear equations with two variables in elementary algebra. This technique consists of isolating one of the variables in one of the equations and substituting that expression in the other equation. The resulting equation is then solved to find the value of the other variable. Finally, this value is substituted into one of the original equations to find the value of the other variable.

Let x be the cost of the banana.

From the statement, we know that:

Solving the equation:

2x + $1 = $1.10

2x = $1.10 - $1

2x = $0.10

x = $0.10 / 2

x = $0.05

Therefore, the cost of the banana is $0.05.

Answer:

To complete the square and rewrite the quadratic function y = x² + 7x + 3 in vertex form, we follow these steps:

Factor out the coefficient of x² from the first two terms:

y = 1(x² + 7x) + 3

Take half of the coefficient of x (which is 7 in this case) and square it. Add this value inside the parentheses, and subtract the same value multiplied by the coefficient of x² (which is 1) outside the parentheses to maintain the same value of the expression:

y = 1(x² + 7x + (7/2)² - (7/2)²) + 3

Simplify inside the parentheses by combining the first three terms using the square of the binomial formula (a + b)² = a² + 2ab + b²:

y = 1(x + 7/2)² - 1/4 + 3

Combine the constant terms to simplify:

y = 1(x + 7/2)² + 11/4

Therefore, the quadratic function y = x² + 7x + 3 can be written in vertex form as y = (x + 7/2)² + 11/4. The vertex is located at the point (-7/2, 11/4).
