Step-by-step explanation:
10q-5r=30
-5r=-10q+30

Answer:
Option D) all of the above are correct
Step-by-step explanation:
We have to find the statements that is true about the central tendency.
a) the calculation of the mean includes every value in your data
The given statement is true.
b) the median is not influenced by a single outlier in large data sets
The above statement is true as the median is less liable to be distorted by outliers. The median is the mid value of data that divides the data in two equal parts.
c) the mode can be multiple values
The above statement is true as mode is the most frequent value in the data and there can be more than 1 mode.
Thus, allthe statements are true.
The first thing you have to do is order them least to greatest. Once that is done you need to find your first, second and third quartile. to find them is simple. You have to find the median of the data set. Then from the number on either side of the median you have to find the median of this data sets. The median of the entire set is your second quartile then the medium to the left is your first and the median to your right is the third quartile. For the number line you need to make numbers that are appropriate for the number range. Then place your least number, the first, second, and third quartile, then place your greatest number. then draw a line up from the median and the first and third quartile and create a box.
