<span>x – 12 ≥ 18
Let's break down the sentence and create an inequality from it. We'll use X to represent the number.
"Twelve fewer than a number is at least 18."
The "Twelve fewer than a number" indicates subtraction, so let's do that.
X - 12
"is at least 18." would be a greater than or equal relationship. So we have
X - 12 ≥ 18
And we're done. The desired equation is:
x – 12 ≥ 18</span>
Answer:
Step-by-step explanation:
Since we have given that
A toy manufacturer claims that the mean time that its top-selling toy captures children's attention is at least 45 minutes.
Since we need to carry out a hypothesis test whether he can refute the claim.
We always take the alternate hypothesis such that it should satisfy the given statement.
And the null hypothesis can be equal to mean or other than that is given in alternate hypothesis.
So, hypothesis :

Answer:
3+n
Step-by-step explanation:
Simple questions but it can be technical atimes, according to the question we are to solve in terms of n, simple...
The sum of 3 and n can be written as 3+n
This cannot be solved further because there are two different variables and it is impossible to add them together
Therefore the final answer is 3+n
But in case a value is given for n we can then substitute and solve further
Hope this will help you
