The correct question is
<span>Yuri computes the mean and standard deviation for the sample data set 12, 14, 9, and 21. he finds the mean is 14. his steps for finding the standard deviation are below. what is the first error he made in computing the standard deviation
</span>
see the picture in the attached figure N 1we know that
The formula for Sample Standard Deviation is indicated in the attached figure N2
in this problem
n=4 and Yuri had to divide in the formula by 3
therefore
the answer is Yuri divided by n instead of n -1
Answer:
Points W, K, and J are collinear. Line CA and line YK intersect at point B. Point W is not contained on line m. The answers will be J,B,W
Step-by-step explanation:
Hope this helped :)
The answer is letter C. Because the y-intercept which is -2 and the slope is negative(which it should go down 2 steps). Originally the slope is rise over run which is 2/4 simplified as 1/2 or -1/2.

The inequality is y < 2x - 3 and the graph of the inequality is graph (a)
<h3>How to isolate y?</h3>
The inequality is given as:
y + 2x < 4x - 3
Subtract 2x from both sides of the inequality
y < 2x - 3
The above inequality uses the < symbol.
This means that the line of the inequality is a dotted line, it is shaded to the right and it crosses the y-axis at y = -3
Hence, the graph of the inequality is graph (a)
