Answer:
-6x + 10
Step-by-step explanation:
7 + 3( 1 − 2x)
Distribute:
=7 + (3) (1) + (3) (−2x)
=7 + 3 + −6x
Combine Like Terms:
=7 + 3 + −6x
=(−6x) + (7 + 3)
= −6x + 10
Answer:
= −6x + 10
hope this helps and is right :)
p.s. i rlly need brainliest
N is the variable I believe.
If the mean is 20.8, one standard deviation each way is adding and subtracting 3.1, so 17.7 and 23.9 (68% of values)
Two standard deviations adding and subtracting 3.1*2 = 6.2, or 14.6 and 27.
Three standard deviations is 11.5 and 30.1
So we have
11.5 - 14.6 - 17.7 - 20.8 - 23.9 - 27 - 30.1
Going left to 11.5 is 3 standard deviations out, so 99.7/2 = 49.85%
Going right to 27 is 2 standard deviations out, so 95/2 = 47.5%
Add those two % to get 97.32%
This is hard to do without a picture so I hope that helps!
