Answer: median = 1.5

Step-by-step explanation:

The mean is the most common measure of center which is synonymous to average. However, the mean is affected by extreme values so it may not be the best measure of center to use in a skewed distribution.

The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.

The median of

0 , 0 , 1 , 1 , 2 , 2 , 2 , 14

Median = (1+2)/2 = 1.5

2x+y=3<br>x-y= 1<br><br>solve the equation ​
svetlana [45]

Answer:

x = 4/3

y = 1/3

Step-by-step explanation:

System of equations! This is set up really well to make the second equation equal x then substitute.

x - y = 1

x = 1 + y

and then our substitution:

2 (1+y) + y = 3

and solve:

2 + 2y + y = 3

3y + 2 = 3

3y = 1

y = 1/3

And now we can substitute that value into one of our equations:

x - (1/3) = 1

x = 4/3

Next we should check by substituting these values into both of our equations:

2 (4/3) + (1/3) = 3

9 / 3 does equal 3 !

(4/3) - (1/3) does equal 1 !

Therefore, x = 4/3 , and y = 1/3
