Mathematics
1 answer:
Studentka2010 [4]2 years ago
3 0

Answer:

13 unit

Step-by-step explanation:

By the distance formula,

The distance between two points (x_1,y_1) and (x_2, y_2) is,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Thus, the distance between B(8,-7) and C(-4,-2) is,

BC=\sqrt{(-4-8)^2+(-2+7)^2}

=\sqrt{(-12)^2+(5)^2}

=\sqrt{144+25}

=\sqrt{169}

=13\text{ unit}

The best measure of center for this data set is the median and its value expressed up to one decimal place is 37.50

Step-by-step explanation:

The best measure of center for this data set is the MEDIAN , and its value expressed up to one decimal place is 37.50.

We have given the data set gives the number of bottles filled by each of the workers in a bottling plant in one day.

The data set is:

{36, 18, 16, 28, 68, 35, 37, 66, 38, 40, 41, 44, 72, 29}

Let us find the median of this data set.

Arrange the values in ascending order:

{16,18,28,29,35,36,37,38,40,41,44,66,68,72}

Median = average of middle entries

Median = 37.5

Therefore the best measure of center for this data set is the median and its value expressed up to one decimal place is 37.50 ....
