The answer is the median m = 117.5.
Explanation:
let's calculate the three central tendency measures:
- mean = μ = (<span>22 + 114 + 115 + 120 + 122 + 125) / 6 = 103
- median = m: we have 6 values, therefore the median will be the average between the third and the fourth value:
</span><span>22 114 115 | 120 122 125
m = (115 + 120) / 2 = 117.5
- mode: all the values appear only once, therefore the mode is not applicable.
Since our values are not symmetrically distributed (we have 22 which differs a lot from the other values), the median should be preferred than the mean as best central tendency measure.

Answer:
2 + (13/4)x = 1/2 + (11/2)y
Step-by-step explanation:
Let each jar of paint used by Liam be x
Let each jar of paint used by Evan be y.
Liam uses 2 quarts of yellow paints and adds 3 1/4 jars of blue paint. so we have
2 + 3 1/4x
= 2 + (13/4)x
Since Evan also uses 1/2 quarts of yellow paints and add 5 1/2 jar of red paint, we have
1/2 + 5 1/2y
= 1/2 + (11/2)y
Since they end up with the same volume of paint, we have
2 + (13/4)x = 1/2 + (11/2)y
