When Bella runs the 400 meter dash, her finishing times are
normally distributed with a mean of 83 seconds and a standard
deviation of 1.5 seconds. Using the empirical rule, determine the
interval of times that represents the middle 99.7% of her finishing
times in the 400 meter race.

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

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
