Aprocess is turning out end items that have defects of type a, or type b, or both. if the probability of type a defect is 0.1 and of type b is 0.2, the probability that an end item will have defects is:

Timed*** there are 8 rows and 8 columns, or 64 squares on a chessboard. suppose you place 1 penny on row 1 column a, 2 pennies on row 1 column b, 4 pennies on row 1 column c, and so on … how many pennies are on each square? a =   b =   c = d =   e =   f = g =   h =

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49
