Step-by-step explanation: just subtract 20-6.57
hint hint u can also use a calculatr
(p-8-m)/(-1+p)=1 1/9;p=1 7/8
(p+1)/(p+8+m)=1 1/9;p=1 7/8
1/(8+m)=10/9;p=15/8
that's as far as it can be solved

The Opposite Is a Positive Number
Step-by-step explanation:
Ex:
-6 opposite is 6
-19 opposite is 19
8 opposite is -8
The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
