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.
Completing the square
alrighty
minus 31 both sides
x²+12x=-31
take 1/2 of the linear coefient and square it
12 is the linear coefient
12/2=6, (6)²=36
add that to both sides
x²+12x+36=36-31
factor perfect square trinomial
(x+6)²=5
square root both sides, remember to take positive and negative root
x+6=+/-√5
so what you want to write is
x+6=√5 and
x+6=-√5
the solutions
minus 6 both sides
x=-6+√5 and -6-√5
Answer:
The answer to your question is 2
Step-by-step explanation:
Process
To solve this problem, just choose two sets of points and use the slope formula to find it.
Formula
slope = (y2 - y1) /(x2 - x1)
- I chose the first two points
Point 1 (5, -3)
Point 2 (6, -1)
x1 = 5 y1 = -3 x2 = 6 y2 = -1
-Substitution
slope = (-1 + 3) / (6 - 5)
-Simplification
slope = 2 / 1
-Result
slope = 2
