A scientific study found that the relationship between the remaining lifespan in days of a rat with a certain disease and the number of doses given to the rat of a new experimental drug meant to treat the disease can be approximated by the equation y = 2x + 30, where x is the number of doses and y is the remaining lifespan. What does 30 represent in the equation?
A
the remaining number of days the rat can be expected to live if it isn't given any doses of the new experimental drug

B
the remaining number of days the rat can be expected live if it is given 28 doses of the new experimental drug

C
the number of doses of the new experimental drug that the rat must be given for its remaining life expectancy to increase by 2 days

D
the number of doses of the new experimental drug that the rat must be given for its remaining life expectancy to increase by 28 days

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
