This might be wrong, but you need to get x be itself on the left side and then after you do that, the x on both sides will cancel. Whenever you try to subtract one x from the other it will cancel them. So technically that's all you can do.
1)
1 = 38
2 = 38
3 = 38
4 = 38
2)
1 = 32
2 = 90
3 = 58
4 = 32
Let me know if I'm wrong.
Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.

<em>Hi there ! </em>
<em>What will be the price of the next model ?</em>
<em>$39000 + $39000×14.4% =</em>
<em>= $39000 + $39000×0.144</em>
<em>= $39000(1 + 0.144)</em>
<em>= $39000×1.144</em>
