Researchers investigated the shear strength of 4 types of tin-lead solder. Each type of solder was used on 5 solder joints (20 joints in total). To investigate possible differences in the mean shear strength between the different types of solder, the researchers carried out a one-way ANOVA in the statistical package R. a. True
b. False

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

Which expression is not a polynomial?

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
