Step-by-step explanation:
Given that out of 400 people 112 agree and 288 disagree
Proportion of people agreeing = 

For confidence interval 90% we have critical value as
1.645
Margin of error =1.645*SE
=
Confidence interval 
√7x × (√x-7 √7)
√7x √(x-7)×7
√7x√7x-49
√7x×(7x-49)
√49x²-343x

Answer:
Step-by-step expthe second term is −5. We include ... the like terms are 2x and 4x, 3y and −5y. What do we do ... b) What number is the coefficient of y ? −4. c) What ... m) 4x² − 5x² + x² = 0. Problem 5. ... d) (5xy − 3x + 2y − 1) − (2xy − 7x − 8y + 6) ... We can therefore state the following rule for subtraction. ... Subtract x² − 5x + 7 from 3x² − 8x − 2.lanation:
