9x = 27x-2
-27x -27x
-18x = -2
/-18 /-18
x = 0.1111 continuing or 1/9
Answer:
4x
Step-by-step explanation:
Mode: 7, Median: 7, Mean: 5.6
Median:
First, we put it in numerical order:
2, 3, 7, 7, 9
Then we crossed out the two on the sides:
3, 7, 7
Then we do it again...
7
Then we are left with 7! So the median is 7!
Mode:
Mode is most common number in the group of number so the number that appeared two times is 7. So the mode is 7.
Mean:
We add all numbers together:
2+7+3+7+9 =28
Then we divide that number by the number of numbers we have:
28/5 = 5.6.

Answer:
<h2>B. 7.1</h2>
Step-by-step explanation:
Given the sample data 2 6 15 9 11 22 1 4 8 19, before we can get the standard deviation, we need to first calculate the mean.
mean = 2 +6 +15 +9 +11 +22 +1 +4 +8 +19/10
mean = 97/10
mean = 9.7
Standard deviation for ungrouped data is expressed using the formula;
<em>Hence the standard deviation of the sample data is 7.1</em>
