If the mean of a given data set is 20.6 and the standard deviation is 2.2 ,where will a majority of data lie :

1 answer:

4 0

If you're paying attention in your statistics class, you know that about 68% of the data lies within one standard deviation of the mean. That is, between
.. 20.6 -2.2 = 18.4
and
.. 20.6 +2.2 = 22.8

Selection A is appropriate.

What is the distance between the two points (5,-2) and (-3,8)

bearhunter [10]

You need to use the distance formula
$d = \sqrt{ {(x - x)}^{2} + {(y - y)}^{2} }$

$\sqrt{ {(5 + 3)}^{2} + {( - 2 - 8)}^{2} }$
so the distance between points (5,-2) and (-3,8) is
$2 \sqrt{41}$
which won't simplify so it stays as is
