In 1986, two research groups sampled consumers on the driving performances of the Dodge Colt versus the Plymouth Champ in a blind road test: that is the consumer did not know if they were driving the Colt or the Champ. However, these cars were identical and only their marketing varied. One research group (A) sampled 66 consumers each day for 60 days (a large number of days to control for weather and other variables), while the other research group (B) sampled 22 consumers each day for 50 days. Which consumer group observed more days in which 60% or more of the consumers tested preferred the Dodge Colt:

In new york city at the spring equinox there are 12 hours 8 minutes of daylight. the longest and shortest days of the year very by two hours and 53 minutes from the equinox in this year the equinox falls on march 21 in this task you use trigonometric function to model the hours of daylight hours on certain days of the year in new york city a.what is the independent and dependent variables? b.find the amplitude and the period of the function. c.create a trigonometric function that describes the hours of sunlight for each day of the year. d. graph the function you build in part c. e. use the function you build in part c to find out how many fewer daylight hours february 10 will have than march 21. you may look at the calendar.

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0
