The team plans to use 30% of all donations and car wash proceeds for new equipment, so they will have $430 * 0.30 = $129 to spend on new equipment.

We can start by finding the total amount of money raised from the car wash and donations on Saturday and Sunday.  If the team charged $5 per car wash, then the total amount of money raised from car washing on Saturday is 25 * 5 = $125. The total amount raised from donations and car washing on Saturday is $125 + 95 = $220. Similarly, the total amount of money raised from car washing on Sunday is 19 * 5 = $95. The total amount raised from donations and car washing on Sunday is $95 + 115 = $210. The total amount of money raised over the weekend is $220 + $210 = $430. The team plans to use 30% of all donations and car wash proceeds for new equipment, so they will have $430 * 0.30 = $129 to spend on new equipment.  Next, we can find the total amount raised from donations over the weekend. On Saturday, the team raised $25 + 95 = $120 from donations. On Sunday, the team raised $19 + 115 = $134 from donations. So, the total amount raised from donations is $120 + $134 = $254. Finally, we can find the total amount the team raised over the weekend by adding the amount raised from car washes and the amount raised from donations: $220 + $254 = $474.

Since the team plans to use 30% of all donations and car wash proceeds for new equipment, they will have 0.30 * $474 = $142.20 to spend on new equipment.

The value of x when y = 1 is 2.

Option D is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 7 is an equation.

We have,

x varies inversely with y.

This means,

x ∝ 1/y

x = k/y

And,

xy = 2

This means,

k = 2

Now,

For y = 1,

xy = 2

x = 2/y

x = 2/1

x = 2

Thus,

x is 2 when y = 1

g(x) = x² - 30x.

Suppose we have a function f(x).

f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).

f(x ± c) = Horizontal left/right shift by c units (x - + c, y).

(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).

f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).

To calculate the sample variance for the homicide rate per 100,000 individuals in a sample of selected cities in the United States, you need to use the following formula:

Sample Variance = (∑ (x - X) 2) / (n - 1)

Where x is each homicide rate value in the sample, X is the mean of the homicide rate values, and n is the number of values in the sample.

For example, if the sample contains the following homicide rate values:

100, 200, 300, 400

The mean (X) would be 250, and the sample variance would be:

Sample Variance = ( ∑ ( x - 250 ) 2) / (4 – 1)

= (100,000 + 50,000 + 10,000 + 0) / 3

= 160,000 / 3

The probability that Jaya likes neither book is 1 - 0.6 = 0.4, or 40%. To two decimal places, the answer is 0.40.

The probability that Jaya will like neither book can be found by subtracting the probability that she likes at least one book from 1.
The probability that Jaya likes at least one book is the sum of the probabilities that she likes the first book, the second book, or both books:
P(likes at least one book) = P(likes first book) + P(likes second book) - P(likes both books)
P(likes at least one book) = 0.5 + 0.4 - 0.3 = 0.6

Step-by-step explanation:

To find the function rule for the relationship between x and f(x), we can perform a linear regression analysis on the given data points. This can be done using a spreadsheet software or a statistical software. One way to do this is to use the equation of a straight line, which is y = mx + b, where y is the output (f(x)), x is the input, m is the slope, and b is the y-intercept.

The slope m can be calculated as:

m = (Δy / Δx) = (f(x2) - f(x1)) / (x2 - x1) = (9 - 6) / (3 - 0) = 3

The y-intercept b can be calculated as:

b = f(x) - mx = 6 - 3x

So the function rule is:

f(x) = 3x + 6

To graph the function, we can plot the given data points and then draw a straight line that passes through those points. The graph of the function should look like this:

[!graph of f(x) = 3x + 6]

The function rule for the relationship between x and f(x) can be found using a similar process. Using the given data points, we can calculate the slope and y-intercept:

m = (Δy / Δx) = (f(x2) - f(x1)) / (x2 - x1) = (-2 - (-3)) / (1 - 0) = 1

b = f(x) - mx = -3 - x

So the function rule is:

f(x) = x - 3

The graph of the function should look like this:

[!graph of f(x) = x - 3]

For the third example, we can find the function rule using a similar process:

m = (Δy / Δx) = (f(x2) - f(x1)) / (x2 - x1) = (6 - 4) / (2 - 1) = 2

b = f(x) - mx = 4 - 2x

So the function rule is:

f(x) = 2x + 4

The graph of the function should look like this:

[!graph of f(x) = 2x + 4]

To find the volume of this solid, we will use the method of cylindrical shells. We will integrate the cross-sectional area of a cylinder, given by πr^2, over the height of the solid. The height of the solid is given by the difference between the upper and lower bounds of the region, which are y = sin(x) and y = 0, respectively. The radius of each cylindrical shell is given by the height y = sin(x).

So, the volume of the solid is given by the integral:

V = ∫[0, π/2] π * [sin(x)]^2 dx

Using the antiderivative of π * sin^2(x), which is -π * cos(x), we can find the definite integral:

V = -π * [cos(x)] from 0 to π/2

Evaluating the definite integral and simplifying, we get:

V = (2π - 2) units^3

So, the volume of the solid is (2π - 2) units^3.

Step-by-step explanation:

V = (2π - 2) units^3

5(x + 5) = 5x + 25

(a + b) + c = c + (a + b)

(x - a)(x - b) = x² - (a + b)x + ab

Before solving the above equation, we need to know the algebraic formula. The algebraic formula is

a(x + b) = ax + ab

1.

- 6(x - 4) + 2(x + 5) = ax + b

⇒ -6x + 24 + 2x + 10 = ax + b

   -6x + 2x + 24 + 10 = ax + b

   -4x + 34 = ax + b

So we get the values ​​a and b.

-4x = ax ⇔ a = -4

b = 34

− 3(x + c) − 4(x + d) = - 7x - 15

-3x - 3c - 4x - 4d = -7x - 15

-3x - 4x - 3c - 4d = -7x - 15

-7x - (3c + 4d) = -7x - 15

-7x + 7x - (3c + 4d) = - 15

- (3c + 4d) = - 15

3c + 4d =  15

Let c = 1

3c + 4d =  15

3(1) + 4d = 15

4d = 15 - 3

4d = 12

Answer: A general solution of a differential equation is a solution that contains all possible solutions of the equation, including all arbitrary constants. It provides a general form of the solution that can be customized to fit the specific conditions of the problem.

For example, the general solution of a second-order linear homogeneous differential equation of the form

y'' + p(x)y' + q(x)y = 0

is a combination of two linearly independent functions, often represented by y = c1y1(x) + c2y2(x), where c1 and c2 are arbitrary constants and y1(x) and y2(x) are two linearly independent solutions of the differential equation.

The general solution represents the most general form of the solution that takes into account all possible solutions, including all arbitrary constants. To find a specific solution, one must apply initial or boundary conditions to determine the values of the arbitrary constants.
