A. use the euclidean algorithm to find gcd(870, 153). show every step and every iteration of the algorithm, but you do not need to show each individual calculation used. b. use the euclidean algorithm to find gcd(4282, 1239). show every step and every iteration of the algorithm, but you do not need to show each individual calculation used.

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.
