In Argument A the conclusion indicator  is "we may infer that" and the conclusion  is Kari is more likely to be pulled over.

In Argument B the conclusion indicator  is "For these reasons" and the conclusion  is You should never run with scissors.

In Argument C the conclusion indicator  is "So" and the conclusion  is Humans do not have free will.

To identify the conclusion of each argument, we can either separate the premises (examples of the author's opinion) from the entire argument or we can identify the conclusion indicators.

Some conclusion indicators include:

therefore, thus, hence, so, for these reasons, we may infer, as a result,consequently, etc

Argument A:

conclusion indicator = we may infer that

Conclusion = Kari is more likely to be pulled over.

Argument B:

conclusion indicator = For these reasons,

Conclusion = You should never run with scissors

Argument C:

conclusion indicator = So,

Conclusion = Humans do not have free will

The second one is also 0.4 and 2/5.

Yes, this means that both of these models are equal to each other. This is because Model 1 is equal to 4/10, while Model 2 is equivalent to 40/100. 4/10 is the same thing as 40/100, though. It's just a little bit more simplified, but the fully simplified answer would be 2/5.

So, therefore, the final answer is that both of these models are equal.

Match the line described on the left with the slope of the line on the right. y = 3‐--------------------------------------undefined 9x – 3y = 18.--------------------------,------- - 2 the line through (5, 7) and (5, – 8) -------0 the line through ( – 4, – 1) and (-1,–7)--- 3. ​

Answers

Answer:

y=3, 0; 9x-3y=18, 3; line through (5, 7) and (5, – 8), undefined; the line through ( – 4, – 1) and (-1,–7), -2;

Step-by-step explanation:

y=3 is a horizontal line so the slope is 0

9x-3y=18 can be written as 3y=9x-18 or y=3x-6 so the slope is 3

the line through (5,7) and (5,-8) is a vertical line since the x value didnt change between the two points so the slope is undefined

we have to find the slope of the line through ( – 4, – 1) and (-1,–7). to do this use the formula (y_2-y_1)/(x_2-x_1)=(-7-(-1))/(-1-(-4))=(-7+1)/(-1+4)=-6/3=-2 so the slope is -2

Answer:

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

What is the greatest value that sin(x) + 1 can have? It isn't 1.

f(90) = sin(90) + 1

f(90) = 1 + 1 = 2

What is the smallest value that sin(x) + 1 can have? It still isn't one.

f(-90) = sin(-90) + 1

f(-90) = -1 + 1 = 0

So the midline is (2 + 0)/2 = 1

Answer:

  (a) 1. Distributive property 2. Combine like terms 3. Addition property of equality 4. Division property of equality

Step-by-step explanation:

Replacement of -1/2(8x +2) by -4x -1 is use of the distributive property, eliminating choices B and D.

In step 3, addition of 1 to both sides of the equation is use of the addition property of equality, eliminating choice C. This leaves only choice A.

_____

Additional comment

This problem makes a distinction between the addition property of equality and the subtraction property of equality. They are essentially the same property, since addition of +1 is the same as subtraction of -1. The result shown in Step 3 could be from addition of +1 to both sides of the equation, or it could be from subtraction of -1 from both sides of the equation.

In general, you want to add the opposite of the number you don't want. Here, that number is -1, so we add +1. Of course, adding an opposite is the same as subtracting.

In short, you can argue both choices A and C have correct justifications. The only reason to prefer choice A is that we usually think of adding positive numbers as addition, and adding negative numbers as subtraction.

The net of a rectangular prism is shown below. What is the total surface area of this prism?

A. 112 cm²
B. 142 cm²
C. 105 cm²
D. 71 cm²

Answers

Answer:   142 cm^2  (choice B)

=========================================================

Explanation:

Think of unwrapping a present and doing so without any unnecessary tearing. That means there aren't any little small pieces thrown away. There are many ways to unwrap a 3D box, and this diagram shows one of many ways. This flat layout is the 2D version of the 3D surfaces.

To find the surface area of the 3D figure, we simply need to find the area of each rectangle in this 2D flat net. Once we know all the little areas, we add them up to get the surface area.

------------------------------

The lowest rectangle is 3 cm by 5 cm, so its area is 3*5 = 15 cm^2. Let A = 15 so we can use it later.

Let's move to the middle row of four rectangles. From left to right, we have these four rectangular areas

3*7 = 21 cm^25*7 = 35 cm^23*7 = 21 cm^25*7 = 35 cm^2

I'll call these results B,C,D,E in the order given above. So B = 21, C = 35, etc.

The rectangle up top has area of 3*5 = 15 cm^2. I'll let F = 15

Lastly, we'll add up the sub-areas to get the grand total

A+B+C+D+E+F = 15+21+35+21+35+15 = 142 cm^2 is the surface area

------------------------------

Another pathway to the answer:

If you can picture how this flat diagram would fold up, then you would see that we'd get a 3D block with the following dimensions

L = 7 cmW = 5 cmH = 3 cm

The order of L,W,H doesn't really matter.

Then we can use the 3D block surface area formula like so

SA = 2*(LW + LH + WH)

SA = 2*(7*5 + 7*3 + 5*3)

SA = 2*(35 + 21 + 15)

SA = 2*71

SA = 142 cm^2 is the surface area

As you can see from the third step, we have "35", "21" and "15" show up again. The 2 out front is because we have 2 copies of each item mentioned.

The average price of a 0.5- carat round diamond is $3700 and the average price of a 0.75- carat diamond is $4950. If the weight and the price of the diamond is linearly related, how much will a 2.5 -carat round diamond cost?

Answers

Since the problem stated the weight and price are in a linear relationship, we can use y=mx+b.

First, let's calculate our slope.

m = (4950-3700)/(0.75-0.5) = 5000

Now, let's solve for b.

3700 = 5000(0.5) + b

Simplify the right side of the equation.

3700 = 2500 + b

Subtract 2500 from both sides

1200 = b

Now our equation looks like this:

y  = 5000x + 1200

Let's plug 2.5 in for x to solve for the diamond cost.

y = 5000(2.5) + 1200

Simplify the right side.

y = 13700

The average price of a 2.5 carat diamond is $13700
