Answer:
the confidence interval is 90 % 0.05 < p < 0.75
and margin of error is 35 %
Step-by-step explanation:
Since 9 out of 10 students is 90 % so the confidence interval is 90 %
Range of Confidence Interval = 2* ME where ME = Margin of Error
0.75 - 0.05 = 2* ME
0.7 = 2 * ME
0.7 / 2 = ME
0.35 = ME or
ME = 35 %

1.
<span>1.5x-1 > 6.5
1.5x>1+6.5
</span>1.5x>7.5, divide by 1.5
x>5, is represented by the region to the right of the vertical line x=5
2.
<span>7x+3 < -25
7x<-25-3
7x<-28, divide by 4:
x<-4
</span>x<-4, is represented by the region to the left of the vertical line x=-4
