Answer: x ≤ -14
Step-by-step explanation:
3 -
x ≥ 10
1) You want to subtract 3 from both sides of the equation: 3 -
x ≥ 10
-3 -3
------------------------
2) Once you subtract 3 from both sides of the equation you'll be able to cancel out 3-3.
3) After, you'll be left with; -
x ≥ 7
4) You'll then want to divide both sides by -
to isolate x.
5) Divide 7 by -
6) X ≥ -14, but then you'll want to flip the inequality since you divided by a negative.
7) X ≤ -14
The 90th percentile is 1.2816 standard deviations from the mean. That tells you the standard deviation is ...
