Answer:
Look at the explanation.
Step-by-step explanation:
Start y=-2x-3 at the Y -3 and X 0, then go up two and to the right one, like a staircase. For y=-x+3 start on Y 3 and X 0 and go down 1 x and 1 y like a downstair staircase with 1 unit down.
I guess you want to find the average speed for the whole journey
average speed = distance travelled / time
the distance from home to the shop = speed * time = 0.5*10 = 5 miles
time for travelling back = distance / speed = 5/30 = 1/6 hours
average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
Answer:
1) the general trend is skewed left because there is more data towards the left of the graph, there are more 1's 2's 3's and 4's than there are of any number on the right of the graph.
2) the median is 3 1122233344567 mark off numbers on either side one by one until you get to the center number which is the median
3) add up all the numbers divide by the number of numbers you have which is 13. you end up with 53/13 which is equal to 4.1
4) the mean because if you added 15 to the end of the data set the median would still be 3 but if you added 15 to the mean the mean would jump to 4.9
