Your first picture would be 148.8
For the second picture could you retake it. It says there are four bicycles and it looks like the table graph has more bikes and costs but I can't see it, so could you scroll it down, so I could see the graph please.
For the third picture it would be 15
You find the mean by adding up all the numbers and dividing your sum by all the amount of numbers they give you
For example, the third one.
It says find the mean of 2, 6, 8, 10, and 49
That means to add all those together, which is 75
Then, you would divide 75 by 5 because they give you 5 numbers
Those 5 numbers are 2, 6, 8, 10 and 49
75/5= 15
Hope this helps :)
