Answer:
-12/7
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.

75/100 = 15/20 , divide by 5 . 75/5= 15
100/5= 20 . Divide by 5 for 15/20 . 15/5= 3 , 20/5= 4
3/4*36 - Cross out 4 and 36. Divide by 4
4/4= 1 , 36/4= 9
3*9= 27
Answer :
75% of 27 =36
Answer:
C
Step-by-step explanation:
to have a common difference of -8.5, the sequence has to consistently go down by 8.5.
in the first one, y would go up by 2 every time x goes up by 1, so its not that one.
in the second one, it does go down by 8.5 the first time but the next time it goes down by 4.25, so it's not consistent.
in the third one, each time it goes down by 8.5 so this is the answer.
the fourth one also isn't correct because the graph shows that it is going up, so you know for sure it's not that one.
