The one-time fling! have you ever purchased an article of clothing (dress, sports jacket, worn the item once to a party, and then returned the purchase? this is called a one-time fling. about 20% of all adults deliberately do a one-time fling and feel no guilt about it! in a group of nine adult friends, what is the probability of the following?

Given that about 20% of adults do one time fling.

That is probability of a person doing fling is . Let it be p.

Then we have to use binomial distribution formula for the given problems.

b(x;n,p)=

A)Probability of no one has done one time fling means x is 0 here.

Hence

b) Probability of at least one person has done fling=1-(probability of no one has done)

                                                                                    =1-0.1342=0.8658

c)Probability of no more than two people have done one time fling means we need to add the probabilities for x=1,x=2 along with x=0.

Hence probability = 0.1342+0.302+0.302 = 0.7382

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
