Try p=rx
Step-by-step explanation:
Answer:
1) -6
2) x = -y +7 if you set all terms equal to zero.
Step-by-step explanation:
1) Isolate x by dividing -42 by 7. x = -6
2) Set the entire expression equal to zero.
x + y -7 = 0
Isolate x on one side of the equation. Remember to change signs when moving terms across the equal sign.
x = -y +7 if the original expression is set equal to zero.

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion 
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value: 
Thus, the Margin of Error E = 




the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:

= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)
