c) No it is not possible. A line graph is usually used to measure and present trends between several items. In this case, it is not possible as there is not increase or decrease in the data collected, only the number of vehicles.

ReplyDeleteb)69.2

c)No,it is not possible.A line graph can only show decrease,increase or constant.Since there is no increase,decrease or constant a line graph would not be appropriate for the information

(a) 28º

ReplyDelete(b) 69.2º

(c) No because this only shows the numbers of the different kind of vehicles at that point of time and you cannot see the increase or decrease of the different kind of vehicles at different point of time.

a) 28º

ReplyDeleteb) 69.2%

c) no, it is impossible because line graph is used to calculate statistics over certain period of time.

a)28 degrees

ReplyDeleteb)69.2%

c) Not it is not possible as a line graph can only show changes in the data. Since there is no changes, it is not possible to use a line graph to collate the above data

a) 28º

ReplyDeleteb) 69.2%

c) No. It is because a line graph shows the increase, constant and decrease rate of the data.

a)28˚

c)No, it is not. Line graphs are only used to measure something over a period of time.

a)28˚

c) No, it is not possible as line graphs are more for measuring a certain object's characteristic over a period of time and so using a line graph for this piece of information would be inappropriate.

a) 28˚

ReplyDeleteb) 69.2%

c) No. line graphs are used to show something over a period of time but this graph has information only for that period of time.

No.A line graph is used to show the increase or decrease pattern of a single object

(a) 28˚

ReplyDelete(b) 69.2%

(c) No. Line graph is only used to show the difference over a period of time.

(a)28°

ReplyDelete(b)69.2%

(c)No, the line graph represents information collected over a period of time while the information showed here is of a specific timing.

(a) 28º

ReplyDelete(b) 69.2%

(c) No. Line Graphs are used to represent an amount changing over a period of time.

a) 28˚

ReplyDeleteb) 69.2%

c) No. Line graphs are used to measure data that was collected over a period of time. Hence, it will not be appropriate to use a line graph.

a) 27.69...~~~ 28 degrees

ReplyDeleteb) 9/13x100=69.230...~~~69.2%

c) no....line graphs are used to compare incline and decline of the SAME thing...it cant be used here
