Answer:
s = 19.7
Step-by-step explanation:
First we need to calculate the mean x' of the sample as:
We sum all the scores and divide them by the number of scores.
Then, the standard deviation s is calculated as:
We square every score less the mean, sum every value, then divide that by the number of scores less 1 and finally, we calculate the square root.
So, the standard deviation of the sample is 19.7
Find slope
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(-1,5) and (5,8)
slope=(8-5)/(5-(-1))=3/(5+1)=3/6=1/2
y=1/2x+b
sub a point
(-1,5)
x=-1, y=5
5=1/2(-1)+b
5=-1/2+b
add 1/2
5 and 1/2=b
y=1/2x+5 and 1/2
y=1/2x+11/2

Answer:
The scale factor is 3.
Step-by-step explanation:
Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).
Therefore, the distance OA is given by 
units.
Again, the coordinates of point A' are (1,-2).
Therefore, the distance OA' is given by 
units.
Hence, the scale factor is 
. (Answer)
