Answer:

A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points. A real world example would be a scatter plot of the number if balloons bought each year and a straight line going diagonally representing the average or goal of the number of balloons bought. The points may be above (signaling that the number of balloons purchased was higher than normal or exceeded the goal) or they may be below (signaling that balloon sales are lower than normal or didnt meet there goals). I hope this helps, if not then I apologize

Answer with explanation:

Line of best fit is the line which describes the relationship between two variables with the help of Linear Equation in two variables.

 The equation of line of best fit is:

   y= a x + b

Where, y and x are related with each other,that is with increase in one other may decrease or with decrease in one other may increase or Both increases in same way.

Real life Example

There are ten bulbs which have to be arranged in a rectangular room.Switch off all the Bulbs.Now you have to arrange the bulbs in the room in such a way that room has maximum intensity of light.

As ceiling of room is like two dimensional coordinate plane.Now you have arranged the bulb.You have to draw a line which is called line of best fit such that as the number of bulbs increases intensity of room increases.The line of best fit may pass all the points where bulb is located  or none of the points where bulb is located or may be single or two or three or more than these points where bulb is located.

A film lasts 2 hours and 35 minutes. Greg is going out at 8.15 . If he starts watching the film at 5.30 will he have time to war
Dmitry [639]

Answer:

Yes, he will have enough time to watch the entire film.

Step-by-step explanation:

5:30 to 6:30 is 1 hour of the movie completed.

6:30 to 7:30 is 2 hours completed.

7:30 plus 30 minutes brings him to 8:00.

8:00 plus the additional 5 minutes brings Greg to 8:05.

His movie ends at 8:05, so he will be able to watch the entire movie before going out.

VashaNatasha [74]

Step-by-step explanation:

Let d be the number of days.

<u>Given the following data;</u>
