Cost of public colleges. the average cost, in dollars, for tuition and fees for in-state students at four- year public colleges over the period 2000-2014 can be modeled by the equation y = 4.065x2 + 370.1x + 3450 where x = 0 corresponds to 2000, x = 1 corresponds to 2001, and so on. based on this model, for what year after 2000 was the average cost $8605? (source: the college board, annual survey of colleges.)

answer: 88

step-by-step explanation:

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
