Nine wolves, eight female and one male, are to be released into the wild three at a time. if the male wolf is to be in the first released group and order does not matter, in how many ways can the first group of three wolves be formed?

We have been given that Nine wolves, eight female and one male, are to be released into the wild three at a time.

We need to choose 1 male wolf out of 1 wolf male. So  we can choose one wolf as:

We can choose 1 male wolf in only 1 way.

Since the female wolfs are identical (order doesn't matter), so we will use combinations.

We can choose 2 female wolves out of 8 as:

Therefore, we can choose 2 female wolves out of 8 female wolves in 28 ways.

To find number of ways in which the first group of three wolves can be formed we will multiply the ways of choosing 1 male wolf and 2 female wolves.

Therefore, the first group of three wolves can be formed in 28 ways.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
