The points on the scatter plot show the different predictions. The straight line drawn is called the line of regression. Errors in prediction for each point can be determined by drawing a vertical line from the point to the line of regression. As seen in the image, all of the prediction points are found on the line except for points (14,25) and (16,25). Therefore, these points contain errors in prediction.

Mrs.Banks has 1/5 of a pot of coffe left. She wants to share the coffe equally among 5 people.What fraction of a pot of coffe wi
Shtirlitz [24]

Each person will receive 1/25 of a pot of coffee.

To find this you divide the fraction 1/5 by 5. When dividing a fraction by a whole number, you put the whole number over 1, flip the numerator and denominator (making it the inverse), then multiply the 2 fractions. So, instead of 1/5 divided by 5, you now have 1/5 times 1/5. Multiply straight across, 1 times 1 is one, and 5 times 5 is 25. Thus making the fraction 1/25.

I hope this helps!
