Which measure is usually the least useful in describing the data for a stem-and-leaf plot? range median mode mean

Mean: For this case would be not useful since in the stem leaf plot is difficult to find this measure with this chart

Step-by-step explanation:

We want construct a stem and leaf plot and we want to find the measure least useful.

And for this case if we analyze the option we have:

Range: That very useful and it can be extracted from the stem and leaf plot

Median: It could be easy to find it with the stem leaf plot

Mode: With a stem leaf plot we can find easily the most repeated value

Mean: For this case would be not useful since in the stem leaf plot is difficult to find this measure with this chart

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.
