Answer:
90
Step-by-step explanation:
The mean is the average:
(92 + 96 + 94 + 88 + x) / 5 ≥ 92
370 + x ≥ 460
x ≥ 90
A graph shows one solution, at ...
... B. x = 9/2
_____
The equation can be resolved to two:
1. For x < -4
... -(x+4) = 3x -5
... 0 = 4x -1 . . . . . . add x+4
... 0 = x -1/4 . . . . . divide by 4
... 1/4 = x . . . . . . . not in the domain x < -4 . . . . no solution
2. For x ≥ -4
... x+4 = 3x -5
... 0 = 2x -9 . . . . . subtract the left side
... 0 = x -9/2 . . . . divide by 2
... 9/2 = x . . . . . . . in the domain x ≥ -4. This is the solution.
Answer:
100%
Step-by-step explanation:
Let X be the fourth score
(95 + 91 + 98 + X)/4 = 96
284 + X = 96 × 4
284 + X = 384
X = 384 - 284
X = 100
