Explanation:
We can rule out "theoretical probability" since that concept deals with doing the math on paper, rather than getting out an actual deck of cards to compute the probability. If your teacher stated "the probability of drawing an ace is 1/13", then s/he would be using theoretical probability. We have a 1 in 13 chance to theoretically pick an ace out of all 52 cards since 4/52 = 1/13. No cards are needed to do such calculations. But if you actually pull out a deck of cards and randomly select them, then you'd be leaning toward empirical or experimental probability.
So in short, we can rule out choice B.
We can also rule out "complement" since the two situations of "drawing a 4" and "drawing a 10" aren't opposite. If it said something like "drawing a red card or drawing a black card", then those two events are opposite. The two events fully compose all the deck of cards (sample space). You either will draw a red one, or a black one, but not both colors at the same time.
So we're down to the answer being either A) outcome or D) event. At first glance, these two terms seem almost identical. However, they mean slightly different things.
Let's pick apart what each of those terms mean.
----------------
The outcome is the result of an event. An event is some specific action that you may or may not want to happen, and it's usually phrased within the parameters your teacher set up.
For example, we can define the event "it rains outside". So we're setting up the specific action of raining. Whether we want it or not doesn't really matter. The outcome would be the actual result of if the event happens or not. So if it does truly rain on day 1, then the outcome "rain" is what is recorded for day 1. Then if its dry on day 2, then "no rain" is the outcome for that second day. And so on.
Going back to the cards, one event could be set up as "selecting a heart card" with the outcome being "selected a 4 of hearts". The event is the rule set up and the outcome is the result we observe. To compute the empirical or experimental probability, we divide the number of times we get a specific event to occur over the total number of possible
---------------
Let's look at another example.
We'll roll a single die that has 6 faces on it. The set of possible outcomes are {1,2,3,4,5,6}. Only one outcome is possible per roll.
If we roll the die and it lands on 5, then the outcome is 5. This is the final result of the trial or experiment.
We can define an event like "A = rolling an even number", and then ask the question "what is the probability event A occurs?" In other words, we would be asking "what is the probability of rolling an even number?"
---------------
I suppose now that I think about it, we can state,
outcome = some single action you observeevent = collection of outcomes (usually some pattern to it)as a loose way of telling the difference between the two terms.
Ultimately, the observations of getting a 4 of hearts and 10 of diamonds are considered an outcome.

What is a 3, 4, 5 triangle?
Answer:
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.

A pet turtle walks towards his food dish at a constant speed in a straight line . His Distance in inches y from his food dish after X seconds is given by Y=3x+12 in the equation y=3x+12 interpret the meaning of the coefficients 3 and the meaning of the number 12
help me pls
Answer:
3.45677
Step-by-step explanation:
The number 3 represents the speed of the pet turtle. And the number 12 represents the distance already covered at t = 0.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
A pet turtle strolls towards his food dish at a consistent speed in an orderly fashion. His Distance in inches y from his food dish after X seconds is given by y = 3x + 12.
In the equation, the number 3 represents the speed of the pet turtle. And the number 12 represents the distance already covered at t = 0.

For all 4 pics
Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
1st pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]
(write equation) Cos 27 (cos 27 = 0.89) = [tex]\frac{x}{20}[/tex]
(new equation) 0. 89 = [tex]\frac{x}{20}[/tex]
(multiply 20 on both sides) 0.89 x 20 = [tex]\frac{x}{20}[/tex] x 20
(solve) 17.8 = x
2nd pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]
(write equation) tan 40 (tan 40 = 0.84) = [tex]\frac{32}{x}[/tex]
(new equation) 0.84 = [tex]\frac{32}{x}[/tex]
(multiply 32 on both sides) 0.84 x 20 = [tex]\frac{32}{x}[/tex] x 20
(solve) 16.8 = x
3rd pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]
(write equation) cos 55 (cos 55 = 0.57) = [tex]\frac{16}{x}[/tex]
(new equation) 0.57 = [tex]\frac{16}{x}[/tex]
(multiply 16 on both sides) 0.57 x 16 = [tex]\frac{16}{x}[/tex] x 16
(solve) 9.1 = x
4th pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]
(write eqaution) tan 42 (tan 42 = 0.90) = [tex]\frac{x}{15}[/tex]
(new equation) 0.90 = [tex]\frac{x}{15}[/tex]
(multiply 15 on both sides) 0.90 x 15 = [tex]\frac{x}{15}[/tex] x 15
(solve) 13.5 = x

El extremo de un segmento de recta es el punto A(2, -4). Si la ordenada del otro extremo es fracción 3 entre 2 de su abscisa, determina las coordenadas del punto, si la longitud del segmento es de 2 raíz cuadrada de 26 espacio fin raíz u.
Answer:
Existen dos posibles soluciones para el extremo faltante del segmento de línea: [tex]B_{1} (x,y) = (4,6)[/tex], [tex]B_{2} (x,y) = (-6.462, -9.693)[/tex].
Step-by-step explanation:
La longitud del segmento comprendido entre [tex]A(x,y) = (2,-4)[/tex] y [tex]B(x,y) = \left(z, \frac{3}{2}\cdot z \right)[/tex] queda descrita por la siguiente identidad pitagórica:
[tex](2\sqrt{26})^{2} = (z-2)^{2}+\left(\frac{3}{2}\cdot z +4 \right)^{2}[/tex] (1)
[tex]104 = (z^{2}-4\cdot z +4) + \left(\frac{9}{4}\cdot z^{2}+12\cdot z +16 \right)[/tex]
[tex]104 = \frac{13}{4}\cdot z^{2}+8\cdot z +20[/tex]
[tex]\frac{13}{4}\cdot z^{2}+8\cdot z -84 = 0[/tex] (2)
Calculamos las raíces mediante la Ecuación General de la Cuadrática:
[tex]z_{1} = 4[/tex], [tex]z_{2} \approx -6.462[/tex]
Esto indica que existen dos posibles soluciones para las coordenadas de B, es decir:
Solución 1 ([tex]z_{1} = 4[/tex])
[tex]B_{1} (x,y) = (4,6)[/tex]
Solución 2 ([tex]z_{2} \approx -6.462[/tex])
[tex]B_{2} (x,y) = (-6.462, -9.693)[/tex]

This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this
composite figure? Use 3.14 for it. Show all calculations that lead to the answer and include units. Please provide steps to prove your answer.
Answer:
148.12m²
Step-by-step explanation:
At first, lets find the area of rectangle.
length = 14m
breadth = 6m
Area of rectangle = length x breadth
= 14 x 6
= 84m²
Now, For the area of sector of the circle,
Given angle (a) = 34
radius = 14m
Area of the sector = a / 360 x pi x r²
= 34/360 x 3.14 x 14²
= 34 / 360 x 3.14 x 196
= 58.12m²
Now adding both areas,
84 + 58.12 = 142.12m²
Segment of a circle is the part of the circle. The total area of the composite figure is 142.1544 m².
What is the area of the segment of a circle?The area of the segment of the circle is given by the formula,
[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]
As it is given that the composite figure is made up of a circular segment and a rectangle, therefore, we will find the area of the rectangle and the area of the circular segment individually.
Area of the rectangle
The area of the rectangle is the product of its length and breadth, therefore, the area is,
[tex]\rm \text{Area of the rectangle} = Length \times breadth[/tex]
[tex]= 14 \times 6\\\\=84\rm\ m^2[/tex]
Area of the sector of the circle
[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]
[tex]= \pi \times 14^2 \times \dfrac{34}{360}\\\\=58.1544\rm\ m^2[/tex]
The total area of the composite figure
The total area of the composite figure
= Area of rectangle + Area of the segment of the circle
= 84 + 58.1544 m²
= 142.1544 m²
Hence, the total area of the composite figure is 142.1544 m².
