y = -4 + 1.4

The mutually exclusive events are:

A = {Chevrolet, Pontiac, Buick}

B = {Ford, Mercedes}

C = {Lincoln, Chrysler}

Explanation:

We will identify the given three events that are mutually exclusive.

From example 2.10

A = {Chevrolet, Pontiac, Buick }

B = {Ford, Mercedes }

C = {Lincoln, Chrysler }

Step 1 of 1

If A∩B=∅ where A and B

are two events then we can say that they are mutually exclusive.

And if there are three or more events then they are mutually exclusive if no two events have an element in common.

Now, events from example 2.10

are:

A = {Chevrolet, Pontiac, Buick}

B = {Ford, Mercedes}

C = {Lincoln, Chrysler}

We can see that all the name card are car brand and their intersection is empty.

Hence, they are mutually exclusive.

Then,

A∩B=∅ and A∩C =∅ and B∩C=∅

Final answer

The mutually exclusive events are:

A = {Chevrolet, Pontiac, Buick}

The coordinates of point T' is (2, -2)

A dilation is a transformation that changes the size of a figure but not its shape.

In a dilation with respect to the origin, a point (x, y) is transformed to a point (kx, ky) where k is a scale factor.

In this case, the point T (3, -3) is transformed under a dilation of 2/3 with respect to the origin.

So the image point is (kx, ky) = (3 * 2/3, -3 * 2/3) = (2, -2)

So the image point of T under a dilation of 2/3 with respect to the origin is (2, -2)

Answer: A) 16.425 in^2.

Step-by-step explanation: The figure is broken down, so let's find the area of the rectangle first. We are given 4 in and 2.3 in, which can be multiplied to get 9.2 in. Now, we need to find the area of the two triangles, but let's start with the one to the left. The area of a triangle is b x h x 1/2. 2.3 in x 2.5 in is 5.75 in, but we need to multiply that by 1/2 which is 2.875 in. Finally, we can find the area of the bottom triangle by using the same formula. 3 in x 2.9 in is 8.7 in, but we need to multiply it by 1/2, which is 4.35 in. Now, all we need to do is add all the areas we found together to get the total area of the figure. 9.2 in + 2.875 in + 4.35 in is 16.425 in^2, which means that option A is your answer.

Let me know if this is right! :)

Answer:

16.425 in²

Step-by-step explanation:

total area of the figure= area of (left triangle+ rectangle+ down triangle)

=1/2*base*height+length*breath+ 1/2*base*height

=1/2*2.5*2.3+4*2.3+1/2*3*(5.2-2.3)

The sketch field of given differential  equation is attached in image .

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.

The equation  y′=f(x,y) gives you a slope at each point in the  (x,y)-plane. And this is the slope a solution y(x) would have at x  if its value was y. In other words,  f(x,y) is the slope of a solution whose graph runs through the point  (x,y). At a point  (x,y), we plot a short line with the slope f(x,y).

We have y'=y2

Given that,

Two expressions,

DE = 4x + 5 and GJ = 3x + 25,

If DE = 4x + 5 and GJ = 3x + 25, and they have the same value, then we can set the two expressions equal to each other:

4x + 5 = 3x + 25

Solving for x, we get:

x = 20

So, when x = 10,

DE = 4 x20 + 5

Answer: 14 eggs

Step-by-step explanation: Hello!

You know that there are 10 chickens that lay eggs every day.  There are 7 neighbors that she needs to give eggs to so that they each get the same amount otherwise there is one egg left over.  We know that each chicken must produce at least one egg per day, meaning that the bare minimum amount of eggs per day is 10.  Let's try 10.

10/7 = 1 and 3/7.  This means that there would be 3 eggs remaining.  This is not possible.  Let's try 11.

11/7 = 1 and 4/7.  This means there would be 4 eggs remaining.  Let's try 14.

14/7 = 2.  This is the smallest number of eggs for each neighbor to get the same amount of eggs each per day (2).  The smallest number of eggs she needs in total is 14.

Gauss-Jordan Elimination is a technique for solving systems of linear equations and for determining the inverse of any invertible matrix.

Gauss-Jordan Elimination is a method for finding the inverse of any invertible matrix and for solving systems of linear equations. It is based on the three simplest row operations one may do on a matrix: Place two of the rows in opposite positions. A nonzero scalar multiplied by one of the rows

Since a similar version was described by Wilhelm Jordan in 1888 in his book "Handbuch der Vermessungskunde" independently of B. I. Clasen, who published something similar in the same year, the procedure known as Gauss-Jordan elimination for converting a matrix into reduced echelon form also includes the name Jordan.

This method, which is also known as row reduction, has two steps: forward elimination and back substitution. These two Gaussian elimination method steps differ from one another not by the operations that can be performed through them but rather by the outcome that is obtained.

The option D. See what x is when y = -5 is not a possible way to evaluate the value of f(-5).

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

The given function is f(x) = 3x² - 2x + 5.

f(-5) is actually the value of y or f(x) when x = -5.

By substituting -5 in place of x of the function, we will get f(-5).

Also we can find the value of f(-5) by graphing the function and finding the y value corresponding to the x value of -5.

Let x be Jenny's hourly rate. Then Mary's hourly rate is x + 0.2x = 1.2x.

The total amount of money they earned for the hours they worked is the same, so we can set up the equation:

30x + 25(1.2x) = 610

Expanding the second term and solving for x:

30x + 30x = 610

60x = 610

x = 10.17

So Jenny's hourly rate is $10.17 and Mary's hourly rate is $12.20.

It will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

Now, According to the question:

"Information available from the question"

A physicist measures the remaining radioactivity in a sample.

She finds that it reduces by 18% each year.

If there was 1.52 g of radioactive material left after 4 years.

In order to find the initial quality of radioactive material, we will use the formula:

Initial Quality = Final Quantity * (1 - Reduction Rate)^Years

We know that -

The final Quantity is 1.52 g, the reduction rate is 18% (or 0.18), and the number of years is 4.

Initial Quantity = 1.52 g × [tex](1-0.18)^4[/tex]

Initial Quantity = 1.52 g × 0.452

Initial Quantity = 0.68 g

Hence, the initial quantity of the radioactive material is 0.68 g.

b. In order to find how many more years it will take for the amount of radioactive material to reduce to 0.2 g, we will use the formula:

Years = log(Final Quality / Initial Quality) / log(1 - Reduction Rate)

We know that -

the final quality is 0.2 g, the initial quality is 0.68 g, and the reduction rate is 18% (or 0.18).

Years = log(0.2 / 0.0.68) / log(1 - 0.18)

Years = 7.15

Therefore, it will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

"The customer yields $780 per year in profits for this retailer."

Customer lifetime value (CLV) is a prediction of the total value a customer will bring to a business over their entire relationship with the company. Retailer profits refer to the financial gain a retailer makes after subtracting all costs, including the cost of goods sold, operating expenses, and taxes, from the revenue generated by their retail sales.

The customer spends $250 a week, so the retailer profits:

If the shopper visits the store every week for a year, the retailer profits:

If this shopper remains loyal for a 10-year lifespan, the retailer profits:

This is the CLV  without considering inflation or any other factors. To consider inflation, we can apply the 8% annual interest rate to calculate the present value of the future profits. The present value of $7,800 over 10 years with an 8% interest rate is approximately $5,100 (the exact value will depend on the method used to calculate the present value).

This question should be provided as:

Assume that a customer shops at a local grocery store spending an average of ​$250 a​ week, resulting in a retailer profit of ​$15 each week from this customer.
