I think the test
I think that x would be 1.5.
6 = 4x, 6/4 = 1.5, so 1/5 = x
Answer: x=4
Step-by-step explanation: You have to distribute the negative signs
x - (4x-7)= 5x-(x+21)
x - 4x + 7 = 5x - x - 21
- 3x + 7 = 4x - 21
28 = 7x
X = 4
99.7% encompasses about 3 standard deviations either side of the mean.
82 ±3*2 = (76, 88)
About 99.7% of the values lie between 76 and 88.
