Answer:
y = x - 3
Step-by-step explanation:
Basically, if the lines are parallel, they have the same slope, right? So that part is already complete
And to get the rest of the equation, plug in the points -2 and 1 into the equation for the x values. Then set the equation to solve for b
After you do that you should get b = -3
The slope is 1 and the y-int is -3

Answer:
Step-by-step explanation:
Given that :
Mean = 7.8
Standard deviation = 0.5
sample size = 30
Sample mean = 7.3 5.4772
The null and the alternative hypothesis is as follows;


The test statistics can be computed as :




The p-value at 0.05 significance level is:
p-value = 1- P( Z < -5.4772)
p value = 0.00001
Decision Rule:
The decision rule is to reject the null hypothesis if p value is less than 0.05
Conclusion:
At the 0.05 significance level, there is sufficient information to reject the null hypothesis. Therefore ,we conclude that college students watch fewer movies a month than high school students.
M = -9 ; solve for m by simplifying both sides of the equation, then isolating the varible
