The '68-95-99.7' rule says
-About 68% of values fall within one standard deviation of the mean.
-About 95% of the values fall within two standard deviations from the mean.
-Almost all of the values — about 99.7% — fall within three standard deviations from the mean.
Here 
Therefore, the probability
The required probability
0.6 would be the same as $0.60 AKA 60 cents and 0.06 would be the same as 6 cents
The scale factor is what u multiply the first image by to get the second image. So by dividing the second image by the first image will give u the scale factor.
6 / 1.5 = 4....so there is a scale factor of 4 because 1.5 * 4 = 6
Combine like terms
8u+3u= 11u
and
9v-5v= 4v
So the answer is 11u+4v
