Using the mean of the data-set, it is found that the missing height in the stem-and-leaf plot is given by:
D. 65 in.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, following the key of the stem-and-left plot, there are 8 observations, given as follows:
54, 55, 56, 61, 63, 64, 70 and the missing value x.
The mean is of 61, hence:
423 + x = 61 x 8
x = 65.
Hence option D is correct.

12,055 is the standard form
The common difference based on the sequence given is 15.
<h3>How to illustrate the sequence?</h3>
It should be noted that the sequence given Isa arithmetic sequence.
The common difference will be the second term minus the first term. This will be:
= 101 - 86
= 15
In conclusion, the difference is 15.

Well, 1 Liter plus 1.5 Liters equals 2.5 Liters. We know that milli means 1000, so there are 1000 milliliters in a liters, so, all we have to do is multiply 2.5 liters by 1000 to get 2,500 milliliters!
