Answer:
Suppose we roll a six-sided number cube. Rolling a number cube is an example of an experiment, or an activity with an observable result. The numbers on the cube are possible results, or outcomes, of this experiment. The set of all possible outcomes of an experiment is called the sample space of the experiment. The sample space for this experiment is \displaystyle \left\{1,2,3,4,5,6\right\}{1,2,3,4,5,6}. An event is any subset of a sample space.
The likelihood of an event is known as probability. The probability of an event \displaystyle pp is a number that always satisfies \displaystyle 0\le p\le 10≤p≤1, where 0 indicates an impossible event and 1 indicates a certain event. A probability model is a mathematical description of an experiment listing all possible outcomes and their associated probabilities. For instance, if there is a 1% chance of winning a raffle and a 99% chance of losing the raffle, a probability model would look much like the table below.
Outcome Probability
Winning the raffle 1%
Losing the raffle 99%
The sum of the probabilities listed in a probability model must equal 1, or 100%.
These formulas will be helpful to solve the problem.

Stanley has two sets of three cards face down on a table. Each set contains: the 2 of hearts, the 5 of diamonds, and the 8 of clubs. He randomly turns over one card from each set.
Find the probability of each event:
a) Both cards are red.
b) The first card is red and the second card is black.
c) Both cards are even numbers.
d) The sum of the numbers is greater than 8.
Which strategy did you use each time?
Please explain your work.`
Answer:
a =4/9 = Both cards red
b =2/9 = 1st red 2nd black
c =8/12 = 2/3 simplified even numbers
d= 8/12 = 2/3 simplified sum adds to 8
Step-by-step explanation:
a) Both cards are red see b) 2/3 x 2/3 = 4/9
Answer 4/9
b) One of each colour red selected 1st then black
Answer = 2/3 x 1/3 = 2/9
Answer = 2/9
b) workings
(P2)Any colour RED
(P2)= S1: ( 2/3, 2/3, 1/3)
(P2) = S2: (2/3, 2/3, 1/3)
RED = 1 x 2/3 x 1/3 = 2/9 first card and second card BLACK= 1 x 1/3 = 1/3
Final = 2/9 x 1/3 = 2/9
Answer = 2/3 x 1/3 = 2/9
c)
(P3) Even numbers
(P3)= S1: ( 2/3, 1/3, 2/3)
(P3) = S2: (2/3, 1/3, 2/3)
12 events 7 outcomes see chart below as two even numbers added will always be even numbers and so will two odds including 5+5 = 10
Answer = 8/12
d)
(P4 ) Numbers that multiply to greater than 8
2 + 2 = 4
2 + 2 = 4
2 + 5 = 7
2 + 8 = 10
5 + 5 = 10
5 + 5 = 10
5 + 2 = 7
5+ 8 = 13
8 + 8 = 16
8 + 8 = 16
8 + 2 = 10
8 + 5 = 13
= 12 events either card and 8 opportunities
Answer = 8/12 simplified = 2/3

If you place a 28-foot ladder against the top of a 15-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.
Pls help
The distance between the bottom of the ladder to the bottom of the building is 24 feet.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that If you place a 28-foot ladder against the top of a 15-foot building,
We need to find how many feet will the bottom of the ladder be from the bottom of the building.
This can be found by using the pythagoras theorem.
Let the ladder be the hypotenuse and wall be the opposite sides of triangle. We need to find the adjacent side.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
15²+x²=28²
225+x²=784
x²=784-225
x²=559
Square root on both sides
x=23.64
x=24 feet.
Hence, 24 feet is the distance between the bottom of the ladder to the bottom of the building

Jack rolled a die 60 times and recorded the results in the table.
What could Jack expect to happen to the probability of getting a four if he increased the number of trials to 450?
A)Jack has no idea what to expect. Until you actually perform the simulation you cannot predict the outcome of the results.
B)Jack should see the experimental probability of getting a four to decrease and come closer to 0.167 due to the Law of Large Numbers.
C)Jack should expect to see a increase in the probability of getting a four. As you increase the number of trials you increase the number of times a four occurred, which raises the probability.
D)Jack should expect to see the probability of getting a four remain the same. If you increase the number of trials you can expect to see similar results as to what you got the first time, therefore the probability will not change.
Answer:
C
Step-by-step explanation:
The number of times it happens the more Fours will occur
The correct option is Jack should see the experimental probability of getting a four to decrease and come closer to 0.167 due to the Law of Large Numbers.
What is probability?
A probability is a number that reflects the chance or likelihood that a particular event will occur.
Given that, Jack rolled a die 60 times, and then he increased the number of trials to 450
The law of large numbers;
The law of large numbers indicates that if an event of probability p is observed repeatedly during independent repetitions, the ratio of the observed frequency of that event to the total number of repetitions approaches p as the number of repetitions becomes arbitrarily large.
Hence, Jack should see the experimental probability of getting a four to decrease and come closer to 0.167 due to the Law of Large Numbers, is the correct answer.

Solve for x: 15x + 121 = 256
Solve the inequality: 4x + 8 > 2x - 10
Solve for x: 5x + 7 = 42
Answer:
Step-by-step explanation:
15x + 121 = 256 the answer is x = 9
4x + 8 > 2x - 10 the answer is x > -9
5x + 7 = 42 the answer is x = 7
Answer:
x=9, x>-9, x=7
Step-by-step explanation:
[tex]15x + 121 = 256 \\ 15x = 256 - 121 \\ 15x = 135 \\ \frac{15x}{15} = \frac{135}{15} \\ x = 9[/tex]
[tex]4x + 8 > 2x - 10 \\ 4x - 2x > - 10 - 8 \\ 2x = - 18 \\ \frac{2x}{2} = \frac{ - 18}{2} \\ x > - 9[/tex]
[tex]5x + 7 = 42 \\ 5x = 42 - 7 \\ 5x = 35 \\ \frac{5x}{5} = \frac{35}{5} \\ x = 7[/tex]

Identify the recursive rule for the sequence: 4, 13, 22, 31, 40, 49
Answer:9
Step-by-step explanation: 4+9=13, 13+9=22, 22+9=31, 31+9=40, 40+9=49.
As you can see, 9 is being added so the answer is 9
Answer:
a(n+1) = a(n) + 9
Step-by-step explanation:
The terms just before and just after each are 9 more than the previous term or 9 less than the previous term. In other words, the common difference is 9.
Thus, the recursive formula is a(n+1) = a(n) + 9

Since 1 2/3 is too large for the blank, and 0.153 is too small, we try C, which is 22%. Convert it to a fraction to make 11/50. If you cross multiply, we would find out that 11/50 is a greater fraction than 2/11 and less than 1.42. Hence, we get C as our answer.
Answer:
C
Step-by-step explanation:
2/11 = 0.18
22% is equivalent to 0.22, which is greater than 0.18, but less than 1.42
