8 + 18a - 2 + 6a

Answer: 24a + 6 would be equivalent to: 8 + 18a - 2 + 6a

Good luck on your assignment and enjoy your day!

What is the data value X if its z value is
aleksley [76]
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
