The total number of degrees, d, in an n-sided polygon is given by the formula d=180(n-2). when janelle solves for n, she gets n=d+360/180. sophie solved the same equation for n and got an equivalent equation. which of the following could be sophie’s equation?

n=d/180 +2

n=d/180 -2

n=d-178

n=d-182

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable
