The correct answer is A. 10
8 divided by 0.8 = 10
10x0.8=8
Answer:
The degrees of freedom for the chi square statistic is 7-4=3
The answer is 3!
explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!
To do this you have to times the number of fabric by the length of each fabric
so you have 6*5/8=30/8=15/4 or 3.75
Answer: The correct option is (A). 3.
Step-by-step explanation: We are given to find the scale factor of dilation from ΔABC to ΔDEF.
As shown in the figure, the lengths of the sides of ΔABC to ΔDEF are
AB = 5 units, BC = 4 units, CA = 3 units,
DE = 15 units, EF = 12 units, FD = 9 units.
We know that the scale factor is given by

Therefore, the scale factor of dilation from from ΔABC to ΔDEF is

Thus, the required scale factor is 3.
Option (A) is correct.
