The 90% confidence interval is (70 - 4, 70 + 4). The margin of error is 4%.
Answer:
no solution
Step-by-step explanation:
2w + 7 = 2(w + 5) - 8
Distribute
2w+7 = 2w+10-8
Combine like terms
2w+7 = 2w+2
Subtract 2w from each side
7 = 2
This is never true so there is no solution
That would be false. 122 = 144
