Combination and permutation are two different things. In combination, the number of possible ways considered do not include the order of the elements as a factor. On the other hand, the order of elements in permutation is important. Using the calculator, 5C4 is equal to C.5
Using <em>statistical concepts</em>, it is found that the standard deviation of the probability distribution is of

When a constant is multiplied to each data in a variable, both the <u>mean and the standard deviation</u> are multiplied by the constant.
In this problem, the standard deviation, which is the square root of the variance, is of:

The price of each is of $1.5, hence:

Answer:
C
Step-by-step explanation:
Try this solution:
Common view of the equation of the circle is (x-a)²+(y-b)²=r², where point (a;b) is centre of the circle, r - radius.
1. using the coordinates of the centre and point (2;13) it is possible to define the radius of the circle: r=√(5²+12²)=13;
the equation is (x+3)²+(y-1)²=13² or (x+3)²+(y-1)²=169;
2. using the coordinates of the centre and the radius: (x-2)²+(y-4)²=6² or (x-2)²+(y-4)²=36.
