3/3 (fraction)
____
3)3
3 divided by 3 (with the division sign)
Step-by-step explanation:
=>a+6a=90-12
=>7a=78
=>a=11,14
Z = (X - mean)/sd
-1 = (28 - mean)/sd
mean - sd = 28 . . . (1)
-0.5 = (34 - mean)/sd
mean - 0.5sd = 34 . . . (2)
(1) - (2) => -0.5sd = -6
sd = -6/-0.5 = 12
From (1), mean = sd + 28 = 12 + 28 = 40
mean = 40
standard deviation = 12
