The mean would be the center value. One line away on either side would be 1 standard Deviation, 2 lines away is 2 deviations and 3 lines away is 3 deviations.

You are told 1 deviation is 36.18

So 2 deviations would be 2 x 36.18 = 72.36 and 3 would be 3 x 36.18 = 108.54

To the left of the middle line subtract from mean

To the right of the middle line add To mean

Number in order from left to right:

595.85, 632.03, 668.21, 704.39, 740.57, 776.75, 812.93

Cindy's age, x, is 3 times her age 6 years ago which equation represents the statement x=3(x-6) or x=3-6x or x=3x-6 or x=3x+6

WINSTONCH [101]

Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
