The fuel efficiency, in miles per gallon of 10 small utility trucks was measured. The results are recorded: 22 25 23 27 15 24 24 24 32 32 23 22 25 22 Find the mean and sample standard deviation of these data. Round to the nearest hundredth.

so, converting firstly the mixed fractions to improper fractions and then "adding".

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:

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
