Answer:
x = 8/3
Step-by-step explanation:
6x + 4 = 3x + 12
3x + 4 = 12
3x = 8
x = 8/3
Use the z-score:
112 - 100
For 112, the z-score is --------------- = 12/15, or 0.8.
15
Next, find the AREA under the standard normal curve TO THE LEFT OF 0.8.
Use either a z-score table or a calculator for this purpose.
Using my calculator, I found that this area is 0.532. That places 112 in the 53rd percentile.
82 would be in a lower percentile: the 12th percentile.
Let me know if you have questions about how to use a calculator to do these calculations.

Answer:
P (HHH) = 1/8
Step-by-step explanation:
We want the probability of HHH
P(HHH) = P (heads and Heads and heads)
When we have an and, we multiply the probability
P(heads 1st time) * p(heads 2nd time) * P (3rd time)
The probability of a heads is 1/2
1/2 * 1/2 * 1/2
P (HHH) = 1/8
