Take 36,5x-29, and 2x-21 and add them. Then set them equal to 46+4x. Solve for x and you should get x=20. Now take this value and substitute it into the expression 2x-21 to find LM. Your answer should be 19.
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>
