Step-by-step explanation:
x-intercept says that a line crosses the x-axis
Substitute y = 0 and solve for x.
As per the statement:
An equation of line is given as:
To find the x-intercept:
Substitute y = 0 and solve for x:
⇒-2x = 18
Divide both sides by -2 we get;
x = -9

The confidence interval of a proportion is given by:
Where 'p' is the proportion of students who responded 'yes', 'z' is the z-score for a 95% confidence interval (which is known to be 1.960), and 'n' is the number of students in the sample.
If the confidence interval is from 0.584 to 0.816, then:
60 students were in the sample.
