Answer:

Step-by-step explanation:

The closer the line of best fit is to the points the more accurate it is.  The correlation coefficient gives a numerical rank, where 1 is a perfect fit and the closer to 0 it is the less accurate it is.

I need the values of the line at the same x values as the scatterplot points.  After you have that take the difference of the value of the line of best fit and the corresponding scatterpoint.  if the point is higher than the line then the resiual will be negative and if the point is lower the residual will be positive.  Do you have the equation of the line of best fit?

STatiana [176]

Answer:

The number of people who voted is 30 people.

Step-by-step explanation:

Given:

Kim was elected class president. She received 3 votes for every 2 that Amy got.

No one else ran.

However, if 8 of the people who voted for Kim had voted for Amy instead, Kim would have received only 1 vote for every 2 that Amy would have gotten

Find:

the number of people voted

Step 1 of 1

The ratio of Kim's votes to Amy's votes is 3:2, so Kim received 3x votes and Amy received 2x votes for some value of x. If 8 of the people had voted for Amy instead of Kim, then Kim would have 3x-8 votes and Amy would have 2x+8 votes. If this had happened, then Amy would have twice as many votes as Kim, so 2x+8=2(3 x-8).

Expanding the right-hand side gives 2x+8=6x-16.

Subtracting $2 x$ from both sides and adding 16 to both sides gives 24=4x, so x=6.

Since 3x+2x=5x people voted, the number of voters is $5 \cdot 6=30$.
