USF freshman expenditure is distributed normally with a mean expenditure of $45.67 and a standard deviation of $5.50. What is the probability that USF freshman expenditure is between 46 and 49.56 dollars?

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
