Addition: -9 + -2 = -11
Substraction: -9 - 2 = -11
Answer:
11.57
Step-by-step explanation:
We have a simple formula to solve this:
where
SS is sum of squares
s^2 is the variance, and
n is the number of data points
We are given all the info to find out s^2. Hence,
X^2 - 5x = 12
x^2 - 5x + 6.25 = 12 + 6.25
(x - 2.5)^2 = 18.25
x - 2.5 = (+-) sqrt 18.25
x = 2.5 (+ - ) 4.27
x = 2.5 + 4.27 = 6.77 <==
x = 2.5 - 4.27 = -1.77 <==
Answer:
<u>The third option</u> 56
Step-by-step explanation:
56 is the middle number but I'm sorry if I'm wrong
Answer:
Quadrant III
Step-by-step explanation:
Quadrant I -> (+x,+y)
Quadrant II -> (-x,+y)
Quadrant III -> (-x,-y)
Quadrant IV -> (+x,-y)
If x and y must both be less than 0, then they must both be negative. Therefore, Quadrant III is your answer.
