A random survey of 25 students in each grade level of a school was conducted to determine whether the students preferred to have less time between classes. The results are shown in the table.

There are 275 students in each grade. Based on the survey results, which statement is the best prediction about all
the students in these grade levels?

45

step-by-step explanation:

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

inch

step-by-step explanation:

yard and mile are too big.
