Answer:
Median
Step-by-step explanation:
This set of data has an extreme outlier, which will throw off the mean. The median, on the other hand, does not change or changes minimally whether or not the outlier is there.
By default, the mean is always better, but if an outlier, such as this one, is too large, the median is better.
Answer:
The Answer is: y = 1/2x + 4
Step-by-step explanation:
From the line, find two points: (-2, 3) and (-4, 2)
Use the equation to find the slope:
m = (y - y1)/(x - x1)
m = (3 - 2)/(-2 - (-4))
m = 1 / -2 + 4
m = 1/2
Start with the point slope form of the equation, take one of the points, (-4, 2), and solve for y:
y - y1 = m(x - x1)
y - 2 = 1/2(x - (-4))
y - 2 = 1/2(x + 4)
y - 2 = 1/2x + 2
y = 1/2x + 4
Proof:
f(-2) = 1/2(-2) + 4
= -1 + 4 = 3, giving (-2, 3)
Hope this helps!! Have an Awesome day!!! :-)
Answer:
x=7/5
Step-by-step explanation:
First you need to get X by itself. You simplify the right side, getting -5, and then subtract 9 from both sides, getting -10x on one side and -14 on the other. Divide both sides by -1, getting 10x=14, divide both sides by 10 which leaves x=14/10. This can be simplified to be 7/5
