Answer:
More formally, statistical power is the probability of finding a statistically significant result, given that there really is a difference (or effect) in the population. ... So, larger sample sizes give more reliable results with greater precision and power, but they also cost more time and money.
2x - 2y = 12
-2x - 3y = -22
solution could be (x,2)
===============
2x - 6y = 10
x + 8y = 5
solution could be : (5,y)
==============
3x - y = -5
x + 4y = 7
solution could be : (x,2)
=============
x + y = 2
2x + y = 13
solution could be : neither....is this one written correctly ?

Answer:
7.595
Step-by-step explanation:
Use PEMDAS
So if we know we need to use the parenthesis first since P stands for parenthesis
So solve (0.25 x 4.1) first.
(0.25 x 4.1) =1.025
We know that (0.25 x 4.1) =1.025 so we plug in 8.62-1.025
When subtracted we get the answer of 7.595
