The number of calls received by a certain ticket agency in a given hour is normally distributed. The mean number of calls is 200, and the standard deviation is 25. During a given hour, what is the probability that the agency will receive

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

a is the right answer
