Answer:
1/4 thus B: is your answer
Step-by-step explanation:
Simplify the following:
(1/6)/(2/3)
Multiply the numerator by the reciprocal of the denominator, (1/6)/(2/3) = 1/6×3/2:
3/(6×2)
3/6 = 3/(3×2) = 1/2:
1/(2×2)
2×2 = 4:
Answer: 1/4
The probability that the cube never lands on 3 is (D) 23.3%.

What is probability?</h3>
- A probability formula can be used to calculate the likelihood of an occurrence by simply dividing the favorable number of possibilities by the entire number of possible outcomes.
To find the probability that the cube never lands on 3:
Given -
Required
- Probability of not landing on 3.
First, we need to get the probability of landing on 3 in a single toss.
For a number cube,
- n(3) = 1 and n(total) = 6
So, the probability is P(3) = 1/6
First, we need to get the probability of not landing on 3 in a single toss.
Opposite probability = 1.
Make P(3') the subject of the formula.
- P(3') = 1 - P(3)
- P(3') = 1 - 1/6
- P(3') = 5/6
In 8 toss, the required probability is (P(3'))⁸
This gives:
- P = (5/6)⁸
- P = 390625/1679616
- P = 0.23256803936
Approximate to 1 decimal place, P = 23.3%.
Therefore, the probability that the cube never lands on 3 is (D) 23.3%.

Answer:
(x+9)/2
Step-by-step explanation:
Answer:
x=36.772
Step-by-step explanation:
1. We assume, that the number 63.4 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 63.4 is 100%, so we can write it down as 63.4=100%.
4. We know, that x is 58% of the output value, so we can write it down as x=58%.
5. Now we have two simple equations:
1) 63.4=100%
2) x=58%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
63.4/x=100%/58%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 58% of 63.4
63.4/x=100/58
(63.4/x)*x=(100/58)*x - we multiply both sides of the equation by x
63.4=1.72413793103*x - we divide both sides of the equation by (1.72413793103) to get x
63.4/1.72413793103=x
36.772=x
x=36.772
now we have:
58% of 63.4=36.772
