Answer:
600m
Step-by-step explanation:
speed = distance/time
*re-arrange to find distance
distance = speed x time
*substitute
distance = 30m/s x 20seconds
distance = 600metres
Answer is C. Mean is the mid-point value and one standard deviation on either side. (100-85=15 and 115-100=15)
The outlier, 78, is removed from the data set shown. 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 How does this affect the range?

Hello.
The range with 78 is 55
without 78 is 22
So the range goes down
Have a nice day
Answer:

24= how much money you have
0.5= cost of each ride
r=number of rides you can ride
21.5= price it takes to enter
Answer:
Step-by-step explanation:
You have the domain. It is given as -1≤x≤1
Now all you have to do is figure out the range which is the y value. At first glance I think it might be 3, but that does not look very logical. I'll post this much of it now and be back in under an hour with a more complete answer.
Of course! How silly of me. There is a minimum of y = 1 in the range which comes from x = 0
I've included a graph so you can see how this all works.
So the range = 1 ≤ y ≤ 3
