What is standard form for linear equations?

ax + by = c

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

Using inductive reasoning, what are the next two number in this set? 2,3/2,4/3,5/4,
