z = 8 + 6x - px Subtract 8 from both sides
z - 8 = 6x - px Factor the x out of 6x - px
z - 8 = x (6 - p) Divide both sides by (6 - p)

= x Switch the sides to make it easier to read
x = <span>

Z-score=(score-mean) standard deviation
test A : z(A)= (90-64)/8=3.25
test B: z(B)= (95-60)/10=35/10=3.5
she did better on test B,
answer is A
It's -60199
hope this helps
