The z-score is the number of standard deviations away from the mean. We first subtract the actual score from the mean, then divide the difference by the standard deviation. In this case, our actual score is 13, so we subtract from the mean of 16, then divide by the SD of 2
(13 - 16) / 2 = -1.5
Answer:
scale factor = 4
Step-by-step explanation:
The ratio of corresponding sides, blue shape to black shape.
The corresponding widths are 1 and 4 , then
scale factor = 
= 4
Here, just substitute the value of n = 7
an = -6(n-1)
an = -6(7-1)
an = -6(6)
an = -36
In short, Your Final Answer would be -36
Hope this helps!
