What is the general form of the equation of a circle with center at (a, b) and radius of length m? A.
x2 + y2 − 2ax − 2by + (a2 + b2 − m2) = 0

B.
x2 + y2 + 2ax + 2by + (a2 + b2 − m2) = 0

C.
x2 + y2 − 2ax − 2by + (a + b − m2) = 0

D.
x2 + y2 + 2ax + 2by + a2 + b2 = -m2

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

both equations and proportions are better.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
