How many different ways could a baking contest be judged if 15 pies are entered and 4 ribbons are awarded?

Answers

This is a question of combination since it does not take into account the order of the pies. The answer would be 1365. There are 1365 ways a baking contest ways can be judged if 4 ribbons are awarded with 15 pie entries.

In case you need the order, then the permutation answer would be 32760.

Answer:

1365

Step-by-step explanation:

We are given that 15 pies are entered in the contest.

Out of 15 , 4 are awarded with ribbons.

Now we are supposed to find How many different ways could a baking contest be judged.

Since the order of pie doesn't matter over here.

So, we will use combination.

$^nC_r=(n!)/(r!(n-r)!)$

Substitute n = 15

r = 4

So, $^(15)C_4=(15!)/(4!(15-4)!)$

$^(15)C_4=(15!)/(4!(11)!)$

$^(15)C_4=(15 * 14* 13 * 12 * 11!)/(4!(11)!)$

$^(15)C_4=(15* 14* 13 * 12)/(4* 3 * 2* 1)$

$^(15)C_4=1365$

Hence there are 1365 ways in which a baking contest could be judged.

Answers

37 days. What I did was 10,656÷24 which equals 444. Then I did 444 divided by 12 which left me with 37. Therefore, the food supply would last 37 days.

Simplify. Write in radical form.
(x^3y^-2/xy)^-1/5

Answers

Answer:

The radical form of the expression $((x^3y^(-2))/(xy))^{(-1)/(5)}$ is $\sqrt[5]{(y^3)/(x^2)}$

Step-by-step explanation:

Given : $((x^3y^(-2))/(xy))^{(-1)/(5)}$

We have to simplify the given expression and write in radical form.

RADICAL FORM is the simplest form of expression that do not involve any negative exponent and power is less than n, where n is the nth root of that expression.

Consider the given expression $((x^3y^(-2))/(xy))^{(-1)/(5)}$

Cancel out the common factor x, we get,

$((x^2y^(-2))/(y))^{(-1)/(5)}$
