The median is the middle number of the data plot. Since there 30 numbers, there isn't a exact middle. To find the median you must add the two middle number then divide by 2.
In this case you must add 87 and 88 which gives 175.
Then divide 175 by 2 which gives 87.5
87.5 is the median
F(x) - g(x) = 3x + 2 - (6x-7) = 3x + 2 - 6x + 7 = -3x + 9;
There is no answer correct!
Answer:
x = 6
y = 13
Step-by-step explanation:
since DE and JK are congruent, they are both 18
to find 'y':
3y - 21 = 18
3y = 39
y = 13
DF and JL are diagonals that are congruent so:
9x - 23 = 7x - 11
2x = 12
x = 6

Answer: -The mean is not affected by the existence of an outlier.
Step-by-step explanation:
An outlier is an ultimate value in a set of data that is very much higher or lower than the other numbers. Mean is the only central tendency which is affected by the outlier. (It also affect the standard deviation)
It can affect the mean of a data set by skewing the results so that the mean is no longer representative of the data set.
The median and the interquartile range is unaffected by the existence of an outlier.
