<span>The standard deviation is a measure of how far dispersed around the mean the individual parts of a distribution are. Therefore, because data set X has a greater spread, its standard deviation is going to be greater than that of data set Y. Items such as the mean, median, or mode are measures of central tendency and do not impact the standard deviation.</span>
Answer:
8/15
Step-by-step explanation:
Since this is a right triangle
tan C = opp side / adjacent side
tan C = 8/15

Step-by-step explanation:
Answer:
y = -1/4x - 2.25
Step-by-step explanation:
If you do this algebraically then use formula:
M= (y2 - y1) / (x2 - x1)
In other words, M= (-3 - (-1)) / (3 - (-5))
M= (-2) / (8)
M= -1/4 <-- This is your slope
To find y-intercept:
Substitute M in the slope-intercept equation (y=mx+b) with -1/4, y=-1/4x+b
Next, Substitute y and x with either point (-5, -1) or (3,-3)
-1 = -1/4(-5) + b <-- Solve for B
-1.25 -1 = 1.25 + b -1.25
-2.25 = b
Now just substitute b and m, and there's your answer:
y = -1/4x - 2.25
Hope this helps!
8(8 + X) = 16
64 + X = 16
-64 -64
X = -48
