(3n)-2=5
Move all numbers without a variable to the right side of the equation
3n=7
Divide 7 by 3
n=2.333
Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405
Since 90 is the mean, the z-score of the mean is always 0.
