It also gave birth to many new nations
(prounounced "y bar") is the mean of the y values
Add up the y values to get
5+7+10+15+18 = 55
Then divide by 5 (because there are five y values) to get
55/5 = 11
Therefore,
The answer is choice C
Answer:
12/4 i really hope this helps i took the test and got a 100
Step-by-step explanation:
Answer:
Mean is 17
Median is 10.5
Mode is 2
Range is 37
Step-by-step explanation:
<u>Mean is the average: 2 + 2 + 6 + 15 + 38 + 39 = 102 / 6 = 17 MEAN</u>
<u />
<u>Median is the middle: 2, 2, 6, 15, 38, 39</u>
Between 6 and 15 -> 15 - 6 = 9 / 2 = 4.5
6 + 4.5 = 10.5
Median is 10.5
<u>Mode is most common: </u><u>2, 2</u><u>, 6, 15, 38, 39</u>
<u />
Mode is 2
<u>Range is the difference between the highest and the lowest number: 39 - 2</u>
37
Range is 37
Ok so you have to calculate all the areas try doing maybe it shows you the answer
