Answer:
2/3
Step-by-step explanation:
(6 -4) / (2 - (-1)) =(2) / (2+1) = 2/3
The slope is the change in Y over the change in X.
Slope = (7-4) / (5-3)
Slope = 3/2
Answer:
OK!!!!!!!!!!!!!!!1
Step-by-step explanation:
Using confidence interval concepts, it is found that:
The margin of error suggests Candidate Smith may receive between 45% and 51% of the votes, while Candidate Jones may receive between 47% and 53%. Because the poll estimates overlap when accounting for margin of error, the poll cannot predict the winner.
<h3>What is a confidence interval?</h3>
It is given by the <u>sample proportion plus/minus the margin of error.</u>
Then, for each candidate, the likely margins of proportion of votes are as follows:
- Candidate Smith: 45% to 51%.
- Candidate Jones: 47% to 53%.
The margin of error suggests Candidate Smith may receive between 45% and 51% of the votes, while Candidate Jones may receive between 47% and 53%. Because the poll estimates overlap when accounting for margin of error, the poll cannot predict the winner.
