Lori ran 5 1/2 km on Monday, 6 1/4 km on Tuesday, 4 1/2 km on Wednesday, and 2 3/4 km on Thursday. What is the average number of kilometres Lori ran?

The average is 4 3/4 km.

you would have to add the distance she ran for each day and then divide by the number of days she ran to find the average.

5 1/2 + 6 1/4 + 4 1/2 + 2 3/4 =19

19 (the total distance ran) divided by 4 (the number of days) = 4 3/4

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
