Lisa leaves her house for a road trip and drives at a rate of 50 mph. keisha leaves her house 1 hour later and drives along the same route at a rate of 60 mph. at any given time t, the distance traveled can be calculated using the formula d = rt, where d represents distance and r represents rate. which system of equations can be used to find how long after lisa departs her house she is passed by keisha?
a) d=50t
d=60t-1

b) d=50t
d=60(t-1)

c) d=50t
d=59t

d) d=50(t-1)
d=60t

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)
