The probability of an event is a value between 0 and 1.total no. of outcomes - 1,2,3,4,5,6
odd number = 1,3,5
or a perfect square = 4
probability - dividing the favorable number of outcomes by the total number of possible outcomes.

Choose the equation of a circle with radius 9 and center (3,-4).
Choose the correct answer below.
○ A. (x+3)² + (y− 4)² = 81
○ B. (x − 3)² + (y+4)² = 81
○ C. (x+3)² + (y−4)² = 9
OD. (x-3)²+(y+4)² =
Answer:
B. (x − 3)² + (y+4)² = 81
Step-by-step explanation:
If a circle has center located at (a, b) and radius of r, the equation of this circle is
(x - a)² + (y-b)² = r²
We have a = 3, b = -4 and r = 9
So equation is
(x - 3)² + y - (-4))² = 9²
==> (x − 3)² + (y+4)² = 81

First, 1 dozen is 12 units, so
[tex]1\frac{1}{2}\text{ dozen people }=\text{ 12 people + 6 people = 18 people}[/tex]Now, to solve the exercise you can use the rule of three. So, you have
*How many pounds of meat are recommended to feed 1 dozen people?
[tex]\begin{gathered} 18\text{ people}\rightarrow4.5\text{ pounds} \\ 12\text{ people}\rightarrow x\text{ pounds} \\ x=\frac{12\text{ people }\ast\text{ 4.5 pounds}}{18\text{ people}} \\ x=\frac{54}{18}\text{ pounds} \\ x=3\text{ pounds} \end{gathered}[/tex]Therefore, 3 pounds of meat is recommended to feed a dozen people.
*How many pounds are recommended to feed 4 people?
[tex]\begin{gathered} 18\text{ people}\rightarrow4.5\text{ pounds} \\ 4\text{ people}\rightarrow x\text{ pounds} \\ x=\frac{4\text{ people }\ast\text{ 4.5 pounds}}{18\text{ people}} \\ x=\frac{18}{18}\text{ pounds} \\ x=1\text{ pound} \end{gathered}[/tex]Therefore, 1 pound of meat is recommended to feed 4 people.

a table shows the cost (in cents) of producing and distributing each coin for the years 2007 and 2014
which coin has a cost in 2014 that is less than 0.95 times the cost in 2007

quarter. 9.78. 8.95
dime. 4.09. 3.91
nickel. 9.53. 8.09
penny. 1.67. 1.66
The dime has a cost in 2014 that is less than 0.95 times the cost in 2007.
To solve this problem by finding out the ratio. We can solve this problem by following a few steps.
According to the question, the cost in 2014 is less than 0.95 times the cost in 2007.
So the ratio is 1: 0.95. Which can be written as, 1/ 0.95 = 100/95 = 20/19 = 20: 19.
Now, we have to find among all those coins which follow the trend of 20: 19.
For the quarter, the ratio is 9.78: 8.95 = 9.78 / 8.95 ≠ 20 : 19For the dime, the ratio is 4.09: 3.91 = 4.09/3.91 ≈20: 19For the nickel, the ratio is = 9.53: 8.09= 9.53. 8.09 ≠ 20: 19For the penny, the ratio is = 1.67: 1.66 = 1.67/1.66 ≠ 20: 19Here only the price of a dime has declined 0.95 times.

11. Find the length of the missing side. 16 25 19
Answer:
x = 14.12
Explanation:
To find the missing side, we will use the cosine law:
[tex]c^2=a^2+b^2-2ab\cos (C)[/tex]Where a, b, and c are the length of the sides of the triangle and C is the measure of the angle formed by the sides a and b.
So, we can use the equation to find the angle formed by the side of length 35 and the side of length 44 (25 + 19 = 44). So, replacing a by 35, b by 44, and c by 16, we get:
[tex]16^2=35^2+44^2-2(35)(44)\cos (\theta)[/tex]Then, solving for θ, we get:
[tex]\begin{gathered} 256=1225+1936-3080\text{cos(}\theta) \\ 256=3161-3080\cos (\theta) \\ 256-3161=-3080\cos (\theta) \\ -2905=-3080\cos (\theta) \\ \frac{-2905}{-3080}=\cos (\theta) \\ 0.9432=\cos (\theta) \\ \cos ^{-1}(0.9432)=\theta \\ 19.41=\theta \end{gathered}[/tex]Now, we can calculate the length of the missing side, using the angle θ = 19.41°, the side with length 35 and the side with length 25 as:
[tex]x^2=35^2+25^2-2(35)(25)\cos (19.41)[/tex]Therefore, the value of x is:
[tex]\begin{gathered} x^2=1225+625-1650.56 \\ x^2=199.44 \\ x=\sqrt[]{199.44} \\ x=14.12 \end{gathered}[/tex]So, the length of the missing side is 14.12

[tex]undefined[/tex]A teacher was helping me but I got force quite the app due to lag can you help me with question C, D, and E !!!
Parts C, D and E
Answer:
Explanation:
C) The maximum height is the highest point on the graph. On the x axis of the graph, each small square is 0.25 units. Thus, the x coordinate of the maximum height is is 1.25. The ball reached maximum height after 1.25 seconds
D) There were two different times when the ball was at 10m.
When y = 10 m, x = 0.5
when y = 10, x = 2
At 0.5 and 2 seconds, the ball was at 10m
E) A the time the when the ball hit the ground, the height is 0. Thus, the time when the ball hits the ground is 3 seconds
A student is initially outside. He is given the choice with a probability of 0.4 of going to the playground, 0.3 of shopping in the mall and 0.3 of returning home. If he is in the playground, he takes 2 hrs of time and then decides to stay in the playground again or return back home. (he can continue to decide to stay in playground like a recursive process) Similarly, If he is in the mall, he takes 3 hrs of time and then decides to stay in the mall again or return back home. (he can continue to decide to stay in mall like a recursive process) For all cases, it takes 1 hr to return home. what is the expected hours the student was outside home?
Based on the probability values, it will take the student 2 hours to stay outside the home
How to determine the expected value of the student?The given parameters are:
Probabilities
P(1) = 0.4
P(2) = 0.3
P(3) = 0.3
Time
Time 1 = 2 hours
Time 2 = 3 hours
Time 3 = 1 hour
When the above are represented on a table, we have the following table of values
Time (x) | 2 3 1
Probability (P(x)) | 0.4 0.3 0.3
The expected value of the student is then calculated as
E(x) = ∑ x * P(x)
Substitute the known values in the above equation
E(x) = 2 * 0.4 + 3 * 0.3 + 1 * 0.3
Evaluate the products
E(x) = 0.8 + 0.9 + 0.3
Evaluate the sum
E(x) = 2

3. What are the values of x where f(x)>0?

Part 1
The y-intercept is when x=0, and [tex]f(0)=(0-7)(0+6)(0-5)=210[/tex]. So, the y-intercept is at (0, 210).

what is mapping?
Any set, including all whole integers, all the points on a line, or all the objects inside a circle, can be mapped. A mapping of the set of all whole numbers onto the set of even numbers is defined by the expression "multiply by two," for instance. A rotation is an internal map of a plane or of all of space.
The vertices of ΔDEF are given by D(2,-4) - D E(1,-1) - E F(5, 1).
According to the rule defining a reflection across the line, y=x should be stated when reflecting a point across the line. Then, the x and y coordinates are switched as follows:
y(x, y) → (y, x)
Let's now use the aforementioned rule to finish mapping the vertices of DEF. Change the x and y coordinate locations as follows:
D(2, –4) gives (-4, 2)D'E(1, –1) gives (-1, 1)E'F(5, 1) gives (1, 5)F'The vertices of the ΔDEF are given by (-4, 2)D', (-1, 1)E' , (1, 5)F' through mapping.
