What is the point-slope form of a line that has a slope of 3 and passes through the point (-1, 4)? Oy-(-1) = 5(x-4)
O 4-yı = 3(-1-x1)
Oy-3=-1[(x-(-4)]
Oy-4 = 3[(x - (-1)]
QUICK PLEASE

Assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.
