20/5=4
Answer:3/4
Answer: 1040
Step-by-step explanation:
just took 65 and mutiply 65$
The critical values for a 90% confidence interval are approximately
, so the confidence interval in this case is roughly
The two points are (-2,3) and (10,3)
The x coordinates of each point are -2 and 10. Add them up and we get -2+10 = 8. Cut this in half to get 8/2 = 4
This is the x coordinate of the midpoint
Do the same for the y coordinates.
Add them up: 3+3 = 6.
Divide by 2: 6/2 = 3
This is the y coordinate of the midpoint
The midpoint is therefore (4,3)
