Find the mean, median, and mode of 13, 30, 16, 19, 20, 22, 25, 31
1 answer:
Answer:
Mean: 22
Median: 21
Mode: No mode
Step-by-step explanation:
<u>Mean:</u>
The sum is the value of all the values divided by the number of values:
which is 22.
<u>Median:</u>
The median is the middle-most value of the data set when arranged from lowest to highest:
13, 16, 19, 20, 22, 25, 30, 31
Here, since there are two middle-most terms, the median would be the average of 20 and 22 (20+22/2), which is 21.
<u>Mode:</u>
The mode is the most occurring value in the data set.
13, 16, 19, 20, 22, 25, 30, 31
Since, in this data set, there is do value that occurs twice, we can say that there is no mode for this data set.

Let 'a' be the number of ounces of 2%-solution in the 25-ounce mixture
and 'b' be the number of ounces of 5%-solution in the 25-ounce mixture.
Since, fluid ounces of each concentration should be combined to make 25 fl oz.
So, a+b=25 (Equation 1)
And, a container of 2% acid solution and a container of 5% acid solution should be combined to make 25 fl oz of 3.2% acid solution.
So, a of 2% + b of 5% = 3.2% of 25
Multiplying the above equation by 100, we get
(Equation 2)
Substituting the value of a=25-b in equation 2, we get
Since, a=25-b
a= 25-10
a=15.
So, 15 fluid ounces of 2% solution combined with 10 ounces of the 5% solution to create a 25-ounce mixture at 3.2% concentration of acid.
