Answer:
the mode is 3 and 5
Step-by-step explanation:
If there is a tie between the modes, it is called bimodal. There can be 2 modes in a data set.
Answer:
2 (x + 2) (x - 1)
Step-by-step explanation:
Simplify the following:
2 x^2 + 2 x - 4
Factor 2 out of 2 x^2 + 2 x - 4:
2 (x^2 + x - 2)
The factors of -2 that sum to 1 are 2 and -1. So, x^2 + x - 2 = (x + 2) (x - 1):
Answer: 2 (x + 2) (x - 1)
Answer:
15/16
Step-by-step explanation:
Answer:
The solution:
X = 16 and Y = -6
Step-by-step explanation:
The equations to be solved are:
x+y = 10 ------- equation 1
x+2y = 4 ----------- equation 2
we can multiply equation 1 by -1 to make the value of x and y negative.
This will give us
-x- y = - 10 ------- equation 3
x+2y = 4 ----------- equation 2
We will now add equations 3 and 2 together so that x will cancel itself out.
this will give us
y = -10 +4 = -6
hence, we have the value of y as -6.
To get the value of x, we can put this value of y into any of the equations above. (I will use equation 1)
x - 6 = 10
from this, we have that x = 4
Therefore, we have our answer as
X = 16 and Y = -6
