Use the following images to answer the question:

a. Write a truth statement about each picture using Euclidean postulates.
b. Write the matching Euclidean postulate.
c. Describe the deductive reasoning you used.

Answer:

P(A ∪ B) = P (A) + P(B) – P(A ∩ B)

Step-by-step explanation:

Conditional probability: p(A|B) is the probability of event A occurring, given that event B occurs. For example, given that you drew a red card, what's the probability that it's a four (p(four|red))=2/26=1/13. So out of the 26 red cards (given a red card), there are two fours so 2/26=1/13.

Answer: Volume = 97.6

Step-by-step explanation:

Volume of the cone first

V = 1/3 h π r²

h = 0.7

r = 2

V = 1/3 × 0.7 × 2² × 3.14

V = 1/3 × 0.7 × 4 × 3.14

V = 1/3 × 8.792

V = 2.93

Then find the volume of the cylinder if the cone was there.

V = π r² h

r = 2

h = 8

V = 3.14 × 2² × 8

V = 3.14 × 4 × 8

V = 3.14 × 32

V = 100.48

Now you subtract the volume of the cone from the cylinder.

100.48 - 2.93 = 97.55

Rounded to the nearest tenth is 97.6

if you divide 10,398 by all numbers 3,2 and 6 have whole numbers:)

Ballons-R-Fun:

cost=(n x 1.25) + 6

Singing Balloons:

cost=(n x 1.45) + 2

* n = number of balloons

If this equation is used:

eg. 5 balloons were order.
Ballons-R-Fun:

cost=(n x 1.25) + 6
cost=(5x1.25) + 6

cost=12.25

Singing balloons:

cost=(n x 1.45) + 2
cost=(5x1.45) + 2

cost=9.25

therefore = singing balloons are cheaper.

Step-by-step explanation:

please mark me as brainlest

Answer: A

Step-by-step explanation:

This is because 25%= 25/100, and that reduces to 1/4. Also, whenever it says something OF something, it means to multiply. In this case, 1/4 OF 1000= 1/4x1000= 250.

*Even though it seems that multiplying will just make the number bigger, when you multiply with a fraction, it actually gets smaller* For example 1/3 of 3= 1/3x3= 1

Answer:

a 1/4 is equal to 25/100

Step-by-step explanation:

25/100 = 0.25

1/4 = 0.25

25*4 is equal to 100

Discussion

I can sympathize with your confusion. You might be helped if you knew what the squares meant. Is 1 square = 1 inch or 4 miles? You don't know and can't tell.  So I'm going to say that 1  square is 1 unit.

Givens

The vertical line is 3 units long.

The horizontal line is 4 units long.

Formula

Area = 1/2 horizontal * vertical or

Area = 1/2 * base * height               Substitute givens into this formula

Substitution and Solution

Area = (1/2) 3*4

Area = (1/2) 12

Answer: Area = 6 units  

Answer: 25

Step-by-step explanation:

3          x

__ =  ___

12      100

If 3 games were won out of a total of 12, we can use this number to determine about how many wins would happen if the total were 100.

We can cross mulltiply with the proportion above:

12x= 300

x= 25

Another method we can use is to use the probability. In other words, 3/12 wins= a probability of 1/4. When they ask how many out of something can be found using an outcome from a previous event, multiply that event by the new number, or 100.

1/4 of the games were won when the total was 12, so out of 100, we can do:

1/4 of 100 = 25.

25 wins expected

Hope this helps :)

Answer:

x + y = 52

y = x + 12

(soccer team) x = 20, (hockey team) y = 32

Step-by-step explanation:

x = students on the soccer team

y = students on the hockey team

x + y = 52

y = x + 12

Substitute y = x +12 to get:

= x + x +12 = 52

= 2x + 12 =52

Isolate x for 2x + 12 = 52: x = 20.

Now incorporate a new equation with x = 20:

y = 20 +12

y = 32

Therefore:

x = 20, y = 32

It is the systematic random sampling

Step-by-step explanation:

    I found this definition online on a khan academy website that will prove that the systematic random sampling is correct:

   "Systematic random sample: Members of the population are put in some order. A starting point is selected at random, and every n^th member is selected to be in the sample."

Hope this helps!

Answer:

Slope is 4.

Step-by-step explanation:

The slope-intercept form is y=mx+b

We have to move the -4x over to create a slope-intercept equation.

∴ y=4x+12

Since m=4, the slope would be 4.

Answer: 4

Step-by-step explanation:

First, you have to arrange the equation in the correct way so that you will be able to get the slope. when -4x is shifted to the other side in order to make y the subject -4x will become +4x, so then it is obvious that the slope is 4! yay!

Answer:

B. 24.28 square feet

Step-by-step explanation:

To find the area of the entire composite figure, you will want to find the area of each shape in it and add them up. Personally, I like to start with the easiest one so in this case I would start with the rectangle.

To find the area of the rectangle, you must multiple length and width (l × w or b × h). So you would multiple 4ft by 3ft in this problem. The area of the rectangle then is 12 squared feet (12 ft²).

Next, find the area of the triangle using the formula 1/2×b×h (base= b; height= h). This is because since triangles are basically just squares and rectangles cut in half, all you would do it do the extra step of multiplying it by 1/2. In this problem, after substituting, you would get 1/2(4)(3). The area of the triangle then is 6 squared feet (6 ft²).

Finally, you want to find the area of the semi-circle. To do so, you must use the formula for finding the area of a circle which is π(r)². It is important to pay attention to what is given in the problem because of including the wrong number in your calculations.

In this problem, you are given the diameter of a circle, but what you need is the radius (per the circle area formula) so all you need to do it half it.

Diameter= 2r or Radius = 1/2D

This gives you the fact that the radius of a circle from this problem is 2 because the diameter is 4. HOWEVER, you need to remember that this problem is not asking you to include the area of a circle, it is asking for a semi-circle. This means that you would have to half the answer you get.

There are two easy ways of doing so for this case like:

1/2 π(2)²    1/4 π (2)²  

Just plug either equation into the calculator and have it solved to have the area of the semi-circle.

The last and easiest step is just adding all 3 areas calculated to get the approximate total area of the figure!
