Answer:
3. 9 - (n ÷ 5 ) 5. 8 x ( 5 x t ) (( i don't know the others ))
Step-by-step explanation:
The factors of the given expression are x , x - 2 and x - 4
So the expression for height and length are x and x - 4
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
