The formula t= +
gives the
total time t (in hours) needed for a
boat to travel upstream a distance
of d miles and then back
downstream the same distance,
where b is the speed of the boat in
still water and c is the speed of the
river's current (both in miles per
hour). How can you write a formula
that gives the speed of the current
in terms of the other variable? What
is the formula? (3 points)

Asample of 200 rom computer chips was selected on each of 30 consecutive days, and the number of nonconforming chips on each day was as follows: the data has been given so that it can be copied into r as a vector. non.conforming = c(10, 15, 21, 19, 34, 16, 5, 24, 8, 21, 32, 14, 14, 19, 18, 20, 12, 23, 10, 19, 20, 18, 13, 26, 33, 14, 12, 21, 12, 27) #construct a p chart by using the following code. you will need to enter your values for pbar, lcl and ucl. pbar = lcl = ucl = plot(non.conforming/200, ylim = c(0,.5)) abline(h = pbar, lty = 2) abline(h = lcl, lty = 3) abline(h = ucl, lty = 3)
