Create a list of 7 numbers with a mean of 6, a median of 6 and a range of 4.

4 5 5 6 7 7 8

Step-by-step explanation:

4 5 5 6 7 7 8

For a median of 6, the 4th (middle) number must be 6.

For a range of 4, the first and last numbers must be 4 and 8, since 8 - 4 = 4.

For a mean of 6, the 7 numbers must add up to 42, since 42/7 = 6.

4 + 5 + 5 +  6 + 7 + 7 + 8 = 42.

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:

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
