Answer:
45.21960784 or 45.2
Step-by-step explanation:
Answer:
Mean is 83.7%
And, the standard deviation is 0.033
Step-by-step explanation:
The computation of the mean and the standard deviation is as follows:
Let us assume the P be the sample proportion
Mean is 83.7%
And, the standard deviation is
= 0.033
to get the equation of any straight line, we simply need two points off of it, let's use those two points in the picture below.
keeping in mind that for the point-slope form, either point will do, in this case we used the second one, but the first one would have worked just the same.
Answer:
x = ± 2i
Step-by-step explanation:
note that = i
x² = - 12 ( take square root of both sides )
x = ± = ± = ± 2i
