Answer: (4,8)
First you have to solve for Y in either equation. I solved for Y in the second equation and my new equation was y=12-x.
Then you plug this new equation into the equation you did not touch. It will become 3x+ (12-x)=20.
Next you solve this equation for X which would be 4.
Lastly you plug in 4 in either equation. I plugged it in the first equation and it became 3(4)+y=20
I hope this helps some :)
Answer:
D. No, because 50% is within the bounds of the confidence interval.
Step-by-step explanation:
"52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus±3%"
This means that the 95% confidence interval for the percentage of people that plan on voting for Robert Smith is
(52-3 = 49%, 52+3 = 55%).
We can't say that he will win the election, because at the 95% confidence level, the proportion is not guaranteed to be above 50%.
So the correct answer is:
D. No, because 50% is within the bounds of the confidence interval.
Answer:
C. 780
Step-by-step explanation:
C(n) = 500 + 4n n = number of students attending = 70
C(70) = 500 + (4*70)
C(70) = 500 + 280
C(70) = 780
