In the game 'rock, paper, scissors', both players make a fist with one hand. On the count of three, the players make either a rock (by keeping their hand in a fist), a sheet of paper (by holding their hand out flat), or a pair of scissors (by sticking out their first two fingers).
If both players make the same thing, it's a tie. If a rock and scissors are played, the rock wins. If scissors and paper are played, the scissors win. If paper and a rock are played, the paper wins.
a) Play at least 20 games of 'rock, paper, scissors' with a friend. Record the results as you go - write down who won, and what with.
b) After you've finished playing, organise your results into a table and use this to estimate some probabilities. Who was most likely to win? Were either of you more likely to play a certain object each time? Could you use this information to help you win more games next time?
If this is for a school assignment, not sure how someone else would record themselves playing rock paper scissors.
A bag contains:
5 red marbles
6 blue marbles
3 green marbles
2 yellow marbles
4 purple marbles
A student draws a random marble from the bag, records its color, and returns it to the bag. The student makes a total of 60 draws. What is a reasonable prediction for the number of times a purple marble will be drawn?

A.
12

B.
10

C.
8

D.
15
Answer:
15
Step-by-step explanation:
60/4 which is the chance it gets out of being drawn
Using the concept of probability, the reasonable prediction for the number of times a purple marble will be drawn is 12 times (option A).
What is a reasonable prediction for the number of times a purple marble will be drawn?To predict the number of times a purple marble will be drawn, we can use the concept of probability. The probability of drawing a purple marble in a single draw is the number of purple marbles (4) divided by the total number of marbles (5 + 6 + 3 + 2 + 4 = 20).
Probability of drawing a purple marble = 4 / 20 = 1/5
Since the student makes a total of 60 draws and each draw is independent (the marble is returned to the bag after each draw), we can use the concept of expected value to predict the number of times a purple marble will be drawn.
Expected value = Total number of draws × Probability of drawing a purple marble
Expected number of times a purple marble will be drawn = 60 × (1/5) = 12

because as far as i know the second one, the surface area of the rectangular prism is 254 square inches.
Answer:
The rectangular prism has 4 lateral faces.
Explanation: a rectangular prism has 4 long faces.
The rectangular prism has a surface area of 254 square inches.
Explanation: use the surface area formula: A=2(wl+hl+hw)
W=7
L=9
H=4
A= 2(7*9+4*9+4*7)
A= 2(127)
A= 254 square inches

A bacteria that starts with 3 cells increases by 15% every hour.
Write an exponential growth equation that models the situation
How many bacteria cells will there be in 13 hours?
Answer:
Step-by-step explanation:
In order to determine the equation, consider that any exponential growth equation can be written as follow:
[tex]f(t)=A(1+r)^t[/tex]
where,
f(t): amount of bacteria after t hours
A: initial amount of bacteria = 3
r: growth rate in decimal form = 0.15 (15%)
t: time in hours
By replacing the previous values into the expression for f(t) you get;
[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]
Hence, the answer is f(t) = 3(1.15)^t
Now, replace t = 13 to determine the amount of bacteria after 13 hours:
[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]
Hence, after 13 hours there are approximately 18 bacteria

A parallelogram has an area of 120 square feet and a height of 6 feet.
What is the length of the base of the parallelogram?
Enter your answer in the box.
*box*
Answer:
20 feet
Step-by-step explanation:
1. We know from here that A = bh (Area = Base x Height).
We are given:
A = 120 ft^2
h = 6 ft
b = ?
2. Let's rearrange our formula (A = bh) so that we find what "b" equals."
Our new formula will be: b = A/h (base = Area / height).
3. Let's apply it to the question and do the required math!
b = A/h
b = 120/6
b = 20 ft
Answer:
b = 20 ft
Step-by-step explanation:
The area of a parallelogram is given by:
A = b*h
where,
A: area = 120 ft^2
b: base = ?
h: height = 6 ft
From the equation for A, solve for b, replace the values of A and h and simplify:
b = A/h
b = 120ft^2/6ft
b = 20ft
Hence, the length of the base of the parallelogram is 20 ft

Answer:
A = 54 units²
Step-by-step explanation:
Area of triangle
[tex]A = \frac{1}{2} \times \text{base} \times \text{perpendicular height}[/tex]
You can read the lengths of the base and the height from the graph. Base is 12 units and height is 9 units. (Count the squares. Or 12 = 13 - 1 and 9 = 14 - 5)
[tex]A = \frac{1}{2} \times 12 \times 9\\A = 54 \text{ units}^2[/tex]

Answer: 840
Step-by-step explanation: 50% is half. All I did was add 420 two time since 420 is half of what this person has to spend.
Answer:
the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.
0.50 times 420= 210
210 is the correct answer and have a great day.
