Answer:
8 = 2 ( (8-7) + (12/4) )
Step-by-step explanation:
2 ( (8-7) + (12/4) )
2 ( ( 1 ) + ( 3 ) )
2 ( 4 ) = 8
It takes a bit of thinking and writing it out on paper to come up with an equation that works and you should definitely practice it so it becomes easier
Y=2x+1
2x-y=2
2x-(2x+1)=2
-1=2
-1+1=2+1
0=3
No solution
Answer:
Z-score = 1.18
Step-by-step explanation:
The z-score measures how many standard deviations from the mean a data is
Therefore the z score is the quotient between the difference between a value and the mean and the standard deviation
![Z =\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
Where
μ is the mean, x is a data of the population and
is the standard deviation
In this case
![\mu =101\\\\\sigma = 3.4\\\\X = 105](https://tex.z-dn.net/?f=%5Cmu%20%3D101%5C%5C%5C%5C%5Csigma%20%3D%203.4%5C%5C%5C%5CX%20%3D%20105)
Then the z-score is
![Z = \frac{105-101}{3.4}\\\\Z = 1.18](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B105-101%7D%7B3.4%7D%5C%5C%5C%5CZ%20%3D%201.18)
