Have you ever played rock-paper-scissors (or Rochambeau)? It’s considered a "fair game" in that the two players are equally likely to win (like a coin toss). Both players simultaneously display one of three hand gestures (rock, paper, or scissors), and the objective is to display a gesture that defeats that of your opponent. The main gist is that rocks break scissors, scissors cut paper, and paper covers rock. We investigated some results of the game rock-paper-scissors, where the researchers had 119 people play rock-paper-scissors against a computer. They found 66 players (55.5%) started with rock, 39 (32.8%) started with paper, and 14 (11.8%) started with scissors. We want to see if players start with scissors with a long-term probability that is different from 1/3.
Answer:
players start with scissors with long term probability that is different from 1/3.
Step-by-step explanation:
Total number of people played rock-paper-scissor= 119
66 players started with rock= 55.5%
39 people started with paper = 32.8%
14 players started with scissor = 11.8 %
Sample proportion =x= 11.8% = 0.118
Population mean = µ= 1/3 = 0.333
Sample size = n=119
We know that test statistic formula is :
Z = x-µ / √(∂/n)
By using the test statistics formula
And putting all values, we get
Z = (0.118 – 0.33)/ √(0.33(1-0.33)/119)
= (0.212) / √(0.33(0.67)/119)
= (0.212) / √(0.2211/119)
= (0.212) / √0.00186
= (0.212) / 0.0431
z= 4.91
players start with scissors with long term probability that is different from 1/3.

which relation is a function ?
Answer:
Bottom left
Step-by-step explanation:
If you can draw a vertical line through a graph and touch only one point, the relation is a function.
The relation shown by Graph III is a function.
Thus, option (C) is correct.
A relation is a function if each input (x-value) is associated with only one output (y-value).
In other words, for every unique value of x, there should be a unique value of y.
The vertical line test is a method used to determine whether a given graph represents a function or not.
Graph I have two output correspond one input.
So, it is not a function.
Graph II have two output correspond one input.
So, it is not a function.
Graph III have one output correspond one input.
So, it is a function.
Graph IV have two output correspond one input.
So, it is not a function.
Therefore, Graph III is a function.
Thus, option (C) is correct.

So this is actually a proportion:
The large triangle to the smaller one:
The angles of the triangles are the same so they are proportional
We know the larger one is 20/8 times the smaller one's sides because
YZ = something times QR so:

A certain university has 18 vehicles available for use by faculty and staff. Five of these are vans and 13 are cars. On a particular day, only two requests for vehicles have been made. Suppose that the two vehicles to be assigned are chosen at random from the 18 vehicles available. (Enter your answers as fractions.) (a) Let E denote the event that the first vehicle assigned is a van. What is P(E)? (b) Let F denote the probability that the second vehicle assigned is a van. What is P(F | E)? (c) Use the results of parts (a) and (b) to calculate P(E ∩ F).
Answer:
a
[tex]P(E) = 0.278 [/tex]
b
[tex]P(F |E) = 0.2353 [/tex]
c
[tex] P(E and F) = 0.0654[/tex]
Step-by-step explanation:
The number of vehicles available is [tex]N = 18[/tex]
The number of vans is k = 5
The number of cars is n = 13
Generally P(E) is mathematically represented as
[tex]P(E) = \frac{k}{N}[/tex]
=> [tex]P(E) = \frac{5}{18}[/tex]
=> [tex]P(E) = 0.278 [/tex]
Generally P(F| E) means the probability that the second vehicle assigned is a van given that the first one selected is a van this mathematically calculated as
[tex]P(F |E) = \frac{5 -1}{18-1}[/tex]
[tex]P(F |E) = \frac{4}{17}[/tex]
[tex]P(F |E) = 0.2353 [/tex]
Generally [tex]P(F | E)[/tex] is also mathematically represented as
[tex]P(F | E) = \frac{P(E and F)}{P(E)}[/tex]
=> [tex] P(E and F) =P(E) * P(F | E)[/tex]
=> [tex] P(E and F) = 0.278 * 0.2353[/tex]
=>[tex] P(E and F) = 0.0654[/tex]

how are reflections mathematical formulas used in the computer industry?
Answer When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Describe the end behavior for the cubic function f (x)=-x^3-4
Answer:
"Cubic functions are functions with a degree of 3 (hence cubic ), which is odd. Linear functions and functions with odd degrees have opposite end behaviors. The format of writing this is:
x → ∞ , f ( x ) → ∞
x → − ∞ , f ( x ) → − ∞
For example, for the picture below, as x goes to ∞
, the y value is also increasing to infinity. However, as x approaches - ∞
, the y value continues to decrease; to test the end behavior of the left, you must view the graph from right to left!!
graph{x^3 [-10, 10, -5, 5]}
Here is an example of a flipped cubic function, graph{-x^3 [-10, 10, -5, 5]}
Just as the parent function (
y = x 3
) has opposite end behaviors, so does this function, with a reflection over the y-axis.
The end behavior of this graph is:
x → ∞ , f ( x ) → − ∞x → − ∞ , f ( x ) → ∞
Even linear functions go in opposite directions, which makes sense considering their degree is an odd number: 1."

2+x+1=2x-3
Answer:
6=x
Step-by-step explanation:
2+x+1=2x-3
Combine like terms
x+3 = 2x-3
Subtract x from each side
x+3-x =2x-3-x
3 = x-3
Add 3 to each side
3+3 =x-3+3
6=x
Answer:
The value of variable 'x' is 6.
Step-by-step explanation:
Solving this problem entails of identifying the value for the variable in the equation. We can start by combing the like terms on the left side of the equation. The terms 2 and 1 are the only common terms so these will be the ones we combine and add.
2 + x + 1 = 2x - 3
(2 + 1) + x = 2x - 3
3 + x = 2x - 3
In this step we will use the subtraction property of equality. This means we need to subtract the term 'x' from both sides of the equation.
3 + x = 2x - 3
3 + x - x = 2x - x - 3
3 = x - 3
This next step involves a similar property to the one we used in the last step. It is known as the addition property of equality. This means we need to add 3 to both sides of the equation. Eventually, we will find the value of the variable.
3 = x - 3
3 + 3 = x - 3 + 3
6 = x
It's always best to represent the value of 'x' with 'x' displayed on the left side of the equation.
9 = x
x = 6
We have now reached the 'point of no return' or the point of the equation where we can no longer simplify it any further. This shows that the value of the variable is 6.

For the point-slope equation, we need the y-intercept and the slope of the line
From the graph, we can see that the y-intercept of the given line is '3'
To find the slope, we will take the line of the graph from (-2,0) to (0,3)
in between these points, we can see that the rise = 3 and the run = 2
Slope = rise / run
Slope = 3/2
Now making the point-slope equation
the general form of these equations is :
y = mx + b (where m is the slope and b is the y-intercept)
Therefore the equation is
y = (3x/2) + 3

119 divided by 17? with remainder?
Answer:
A number, when divided by 119, leaves a remainder of 19. If it is divided by 17, it will leave a remainder of 2
Step-by-step explanation:
There is no remainder, and the quotient is 7.
When dividing 119 by 17, we find:
119 ÷ 17 = 7
The quotient is 7. However, there is no remainder because 119 is evenly divisible by 17.
Therefore, 119 divided by 17 is 7 with no remainder.

oes regular exercise reduce the risk of a heart attack? Provided are two ways to study this question. A researcher finds 20002000 men older than age 4040 who exercise regularly and have not had heart attacks. She matches each with a similar man who does not exercise regularly, and she follows both groups for 55 years. Another researcher finds 40004000 men older than age 4040 who have not had heart attacks and are willing to participate in a study. She assigns 20002000 of the men to a regular program of supervised exercise. The other 20002000 continue their usual habits. The researcher follows both groups for 55 years. Select the correct explanation clearly detailing why the second design will produce more trustworthy data.
Answer:
The first design does not specify the age and the number of the group not exercising.
Step-by-step explanation:
The second design will produce more trustworthy data because there are equal number of men above the age of 40 grouped into two categories those who exercise and those who do not exercise.
The first design does not produce such accurate results because the two sample sizes may be quite different and the second group may have candidates of any age other than 40.
The null hypothesis for this design will be u ≠ 40 against the alternate hypothesis that u= 40.
This will give a two tailed test.
All the result possibilities will be for both men aged above 40 and below 40 excluding out only the 40 aged men.
In the second design the sample sizes are same and the both samples may have men aged older than 40
The null hypothesis for this design will be u => 40 (Mean is greater and equal to 40) against the claim u < 40 .
This will give a one tailed test.
So this design will give better results.
All the result possibilities will be for men aged above 40.
