The formula for this type of question is z=x-u/y
z=-2 (z-value)
u = 27 (mean)
y = 4 (standard deviation)
Therefore -2=x-27/4
You now figure this out like a normal equation
4x-2=4 X x-27/4
-8+27= x-27+27
19=x
Therefore the data value of x is 19
Answer:
12/6-1/6=11/6 simplified to 1 5/6
Step-by-step explanation:
to make this easier make sure all fractions have the same denominator 6/3x2/2=12/6 since they now have the same denominator add 12/6+-1/6=11/6
adding a negative(6/3+-1/6) is the same as subtracting a positive(6/3-1/6)
<u>answer:</u>
