Y=8x
Ask for a step by step explanation. :)
Hope this helps.
(x1 , y1) (x2 , y2 )
these are two coordinates
the distance between them is
square root of [ (x2 minus x1) to the square plus ( y2 minus y1) to the square }
for u si square root of { -6-4) to the square + (3-3) to the square]

B. The answer is the same irrespective of the sample sizes.
Step-by-step explanation:
Given that an article in the November 1983 Consumer Reports compared various types of batteries. The average lifetimes of Duracell Alkaline AA batteries and Eveready Energizer Alkaline AA batteries were given as 4.1 hours and 4.5 hours, respectively
Let X be the sample average lifetime of 81 Duracell and Y be the sample average lifetime of 81 Eveready Energizer batteries.
Now we have sample mean difference does not depend about the sample sizes.
This is because
E(X-Y) = E(X)-E(Y) for all X and Y
Mean of X-Y =
This does not depend on the specified sample sizes
B. The answer is the same irrespective of the sample sizes.
