Corrine wrote temperatures in degrees celsius and the equivalent temperatures in degrees fahrenheit. equivalent temperatures celsius –10 5 10 20 fahrenheit 14 41 50 68 which explains how corrine could determine if the temperatures vary directly? compare the equivalent temperatures as a ratio; if the ratios are equivalent, then the temperatures vary directly. draw a graph of the temperatures; if the points form a straight line, then the temperatures vary directly. write an equation that converts one temperature to another; if the temperatures satisfy the equation, then they vary directly. look for a pattern in the table; if the pattern is consistent, then the temperatures vary directly.

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

Suppose your school costs for this term were $4900 and financial aid covered 3/4 of that amount. how much did financial aid cover? and how much do you still have to pay?

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
