Answer: Choice C)
--------------------------------------
mean = xbar = (2400+1750+1900+2500+2250+2100)/6
mean = 2150
Subtract the data values from the mean to get
2400-2150 = 250
1750-2150 = -400
1900-2150 = -250
2500-2150 = 350
2250-2150 = 100
2100-2150 = -50
The differences are: 250, -400, -250, 350, 100, -50
Then you square those values and add up the squares
(250)^2 + (-400)^2 + (-250)^2 + (350)^2 + (100)^2 + (-50)^2 = 420,000
Answer:
it is 5/5, or if that doesn't work its 1 just in case you need to simplify
Step-by-step explanation:
from the first point, count how many squares go up, the count how many squares to the right, so up 5 over 5
Answer:
36 minutes
Step-by-step explanation:
helicopter 1 is ahead of helicopter 2 by 90 miles
the difference in their speeds is 150 mph
90/150=3/5 of hour
3/5*60=36 minutes
If 5y-10=0 it would equal 2. Add ten to both sides and then divide 5 to both sides which leaves you with y=2
Answer:
+5 is greater that -5 and is also a opposite integer.
