Step-by-step explanation:
Answer:
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
Step-by-step explanation:
X=3
Y=2
Use the "Guess and Check Method"
For example, I inputed 2 for X and found that it was too small to work for the second equation, so I put in 3. Then for Y, I input 2 because 3+2=5. I put 2 in to replace Y in the second equation (3x-y=7) to see that 9-2=7. Therefore, X=3 and Y=2
Answer:
5: yes he could easily chose bigger looking families to get the result he wants
6: no he has isn't choosing people and has no idea the answers presumibly
7: no it's not something that they could choose or know what is going to happen, therefore or can't be biased.
I'm not sure if I did it right but I think that's what it's asking sorry if I'm wrong
