-1(5x+1)
-5x-1
the (-) in front is just a short way to put (-1)
What are you trying to say? do you actually need help or what?
well, we know the actual distance is 612, however the estimate is 735, is off by 735 - 612 = 123.
now if we take 612 to be the 100%, what is 123 off of it in percentage?
Answer:
9 tenths
Step-by-step explanation:
Yes, that's true PROVIDED your test scores are normally distributed.
If they are, then more than 99% of your test scores are within three
standard deviations of the mean.
You told us that 3-sigma = 5.4 . So less than one score out of every
hundred tests you take is lower than 86.6 or higher than 97.4 .
You are remarkably consistent, so I guess Jupiter must have been
in its ascendancy next door to the house of Andromeda about an
hour before you were born, or some such nonsense.
