Please show work for full credit! 10^6/ 10^2= 10^3 Why is that false?

1 answer:

7 0

10^6/10² = 10³

10^(6 - 2) = 10³

10^4 = 10³

10000 = 1000

this is false because both sides are not equal to each other which is not a solution.

hope this helps, God bless!

A sample of values has a mean of 500.0 and a standard deviation of 50.0. use the range rule of thumb to find estimates for the m

leonid [27]

The Range Rule of Thumb says that the range is about four times the standard deviation. (i.e. two standard deviations to the left and two standard deviations to the right of the mean).

Given that the mean is 500 and the standard deviation is 50, then

The minimum and the maximum "usual" values are given by

$500\pm2(50)=500\pm100 \\ \\ =(500-100,\ 500+100)=(400,\ 600)$

Therefore, the minimun "usual" value is 400 while the maximum "usual" value is 600.
