Need asap! 10 points braniliest 5 star and a museum surveyed three groups of 5 members to find out how many times the members visited the museum in the past year. the table shows the results of the three samples. survey visits to the museum group 1: {4, 10, 6, 3, 8} group 2: {3, 1, 2, 1, 2} group 3: {7, 9, 3, 4, 7} identify any surveys that are likely biased. based on the unbiased surveys, estimate the mean number of visits per member in the past year. enter your answer in the box. round to the nearest whole number.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
