Answer: N=15
Step-by-step explanation: This is because (4n-18) when solved needs to equal 42. So when solving this you would change the equation to 42=4n-18 and then you need to isolate n. In order to do that you do the opposite so your equation becomes 42+18=4n or (60)=4n. And then you divide 60/4 and get n by itself. Therefore N=15.
Minimum=25
first quartile= 30
Third quartile=45
Maximum=55
Answer:
14x+1
Step-by-step explanation:
We add the variables together so it would be 14x. We can't add the 1 so 14x+1.
