1) from smaller to higher:
1,5,11,11,17
2) find the mean
<span>1 + 5 + 11 + 11 + 17 = </span><span>45
</span>mean = 45/5 = 9
Variance = Σ(x- mean)²/(N-1)
[(1-9)² + (5-9)²+(11-9)² + (11-9)²+ (17-9)² ]'(5-1) = 38
Variance = 38
Hello there! As far as we can see, the y-intercept is 2. Going up 2 helps move the line up by 2. We can go ahead and eliminate C, because that equation only goes up one, and D, because we don't go down any. We have the points (1, 3) and (2, 4). We add the x-value and we can see that 1 + 2 is 3 and 2 + 2 is 4. The only equation that fits the line at all is A. Therefore, the answer is A.
