This relates to behavioral economics because when you’re short on supplies or ideas, you become stressed and you try <span>to figure out how you come up with what you need.</span>
Answer:
Step-by-step explanation:
→ Multiply everything by 2
→ Expand out the bracket
→ Simplify
→ Divide both sides by 4 to isolate x
Hello!
Answer:
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
<em>First, you switch sides. *Group like terms*</em>
<em>Then, you add the similar to elements. You can also add the numbers from left to right.</em>
, is the correct answer.
Hope this helps!
Have a nice day! :)
Is it 5^6 - 5^11 = 5x × (1-5y)?
5^6 - 5^11 = 5^(6-11) = 5^(-5) = 1/(5^5)
So 1/3125 = 5x - 5(5y)
1/3125 = 5(x-5y)
1/3125/5 = x-5y
0.000064 = x - 5y
The probability that the divisor chosen is a perfect square is found to be 1/22 which is m:n.
<h3>What exactly is meant by probability?</h3>
- Probability is synonymous with possibility. It is a mathematical branch that deals with the occurrence of a random event.
- The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of events occurring.
Given: Randomly, a positive integer divisor of 12! is selected.
Prime factorization of 12! = 2¹⁰ × 3⁵ × 5² × 7¹ × 11
Total divisors of 12! = 11 × 6 × 3 × 2 × 2
- Each number in the prime factorization must have an even exponent in order to construct a perfect square divisor.
- In the prime factorization, the divisor cannot have any factors of 7 and 11 because there is only one of each in 12!.
- There are 6 × 3 × 2 perfect squares as a result.
The probability that the divisor chosen is a perfect square is given as:
(6 × 3 × 2)/(11 × 6 × 3 × 2 × 2)
= 1/22
=m/n
Therefore, the probability that the divisor chosen is a perfect square is found to be 1/22 which is m:n.
