The standard equation of a circle with centre (xc,yc) and radius R is given by
Substituting
centre (xc,yc) = (4,-3)
R=2.5
The equation is therefore
or
(x-4)^2+(y+3)^2=6.25
Answer:
(A)Barnsboro Bank has more variation.
Step-by-step explanation:
The coefficient of variation of a set is given by the following formula
In which M is the mean and S is the standard deviation.
The higher the coefficient, the higher the variation of the set.
Barnsboro National Bank
So
Wellington S&L
So
The Barnsboro National Bank has the highest coefficient, so it has more variation.
The correct answer is:
(A)Barnsboro Bank has more variation.
Answer: C is the correct answer
Step-by-step explanation:
Answer:
Yes, she is correct.
Explanation:
21 has the following factors; 1,3,7,21 and 21 is not a factor of 56 so the GCF is 7.
21/3 is 7 and 56/8 is 7 therefore the expression is also correct.
