Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
x + y = 1 → (1)
2y - x = 8 → (2)
Adding the 2 equations term by term will eliminate the x- term
(x - x) + (y + 2y) = (1 + 8), that is
3y = 9 ( divide both sides by 3 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for y
Substituting y = 3 in (1)
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Solution is (- 2, 3 )
To find the mode you need to put all the numbers given in order, then count them and decide which number occurs the most.
Given the number you have here, we're going to put them in order, like so,
78, 78, 83, 85, 89, 91, 95, 98 (they were in order already)
Now we see which number occurs the most.
The number would be 78
