A board game is played by moving a counter S space forward at a time, where S is determined by the following rule: A fair six-sided dice is thrown once. S is half the number shown on the dice if that number is even; otherwise S is twice the number shown on the dice.
1. Write out a table showing the possible value of S and their possibilities.
2. Find the probability that, in a single turn, a player moves their counter forward more than 2 spaces.
The table showing the possible value of S and their possibilities is attached below,
The probability that a player moves their counter forward more than 2 spaces is 0.5.
The Probability is the ratio of favorable outcomes to total number of outcomes. The probability of an event must be less than 1 as the sum of all probabilities of events is equal to 1.
Here, If the number on the dice is even, S is half that number; if it is not even, S is double that amount. The table showing the possible value of S and their possibilities is attached below,
Now, finding the probability that a player moves their counter forward more than 2 spaces,
As seen from the table, the number of favorable outcomes where the player moves the counter more than 2 spaces is 3.
The total number of outcomes is 6. so, the probability will be,
Probability [tex]=\frac{3}{6}[/tex]
[tex]=\frac{1}{2} \\\\=0.5[/tex]
Hence, the probability that a player moves their counter forward more than 2 spaces is 0.5.

while eating out, mike and joe each tipped their server 22 dollars. mike tipped 10\% of his bill and joe tipped 20\ % of his bill. what was the difference, in dollars between their bills?
Joe, for the most part, tipped 20% of his bill, compared to 10% for Mike, which is particularly noteworthy. The actually difference between their invoices in dollars was approximately 10.
Let be Mike's bill and be Joe's bill.
(10/100) *m = 2
M = 20
(20/200 )*j = 2
J = 10

helen buys two pineapples she pays with a £5 note and gets £3.60 change work out the cost of one pineapple
Answer:
Each pineapple costs £0.70.
Step-by-step explanation:
Let P be the number of pineapples Helen purchased and C the cost per pineapple, in £.
Helen's total cost would be: P*C = total cost.
The total cost is the difference between £5 and £3.60, which is £1.40.
We are given P (the number of pineapples, 2) and the total cost (£1.40) , so enter those numbers in the equation:
P*C = total cost
2*C = £1.40
C = £0.70
Find the value of x. 50 points
Answer:
x = 53°
Step-by-step explanation:
Forming the equation,
→ x + (2x + 21°) = 180°
Now the value of x will be,
→ x + (2x + 21°) = 180°
→ 3x = 180° - 21°
→ x = 159°/3
→ [ x = 53° ]
Hence, the value of x is 53°.

The percentage statement 28 is 35% of 80 is written in the form
a/b = p/100 as 28/80 = 35/100.
Explain the term percentages?A ratio or value that can be stated as a fraction over 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its total and then multiply it by 100.The proportion usually applies to a component per hundred. Per 100 refers to what the word percent means.For the given question.
The statement defining the percentage is ;
28 is 35% of 80.
This can be written as;
35% of 80 = 28
Solve percentage.
35×80/100 = 28
35/100 = 28/80
Or,
28/80 = 35/100
This is the form
a/b = p/100
a = 28
b = 80
p = 35
Thus, the percentage statement 28 is 35% of 80 is written in the form

Suppose g(x) = f(x + 2) - 3. Which statement best compares the graph of g(x)
with the graph of f(x)?
• A. The graph of g(x) is shifted 2 units left and 3 units up.
• B. The graph of g(x) is shifted 2 units right and 3 units down. 3
• C. The graph of g(x) is shifted 2 units right and 3 units
up.
• D. The graph of g(x) is shifted 2 units left and 3 units down.
We deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit up in the graph of g(x). The best choice is C.
Describe a graph.A diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.
Right-shift a function
Inside the function's argument, subtract. For instance, is essentially moved b units to the right.
You go to the right while subtracting from the parameter of the function.
Accordingly, f(x) is moved two units to the right in g(x) = f(x - 2).
also to advance a function
Outside of the function, add. For instance, is essentially shifted up units.
G(x) = f(x - 2) + 3 hence says that f(x) is shifted up by 3 units.
Overall, then, using two transformations, we deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit upswing in the graph of g(x).
Therefore, choice C is right.

Why is every rhombus a parallelogram but not every parallelogram is a rhombus? Why is every square a rectangle but not every rectangle is a square? Why is every square a rhombus but not every rhombus
square?
A rhombus is a parallelogram because the opposite sides are parallel but every parallelogram is not a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.
We need to identify the properties of the given figure in order to answer why one figure can not be the other one:
A rhombus has all sides equal as well as parallel but all angles might not be right angles.
A square has all four sides equal and has 4 right angles.
A rectangle has equal opposite sides and 4 right angles.
A parallelogram has opposite parallel sides.
Hence, a rhombus can be a parallelogram because the opposite sides are parallel but every parallelogram can not be a rhombus because all sides may not be equal.
