i dont want to assume all the other people participating in after school activities are girls but if they are, the answer is 108.
180 = 100%
x = 40%
the information above shows that 60% are girls
60% of 180 = 108 or 0.60 x 180 = 108
the answer is 108
hope this is helpful!

D.1 sig fig
Since approximately 68% of a (roughly) normal distribution falls within one standard deviation of the mean, that leaves 32% that falls outside, and by symmetry 16% should lie above one standard deviation of the mean.
