Three out of seven students in the cafeteria line are chosen to answer survey questions. How many different combinations of thre
Hatshy [7]

Answer:

35 possible combinations would be there.

Step-by-step explanation:

We have total of seven students we have to choose three out of those seven

^{n}C_r=\frac{n!}{r!\cdot (n-r)!}

n is the total possibilities n =7 in the given case

And r is the chosen ones

Hence, r=3 in the given case.

Substituting the values of n and r in the formula we get

^{7}C_3

\frac{7!}{3!(7-3)!}

\frac{7!}{3!\cdot 4!}

Using n!=n(n-1)----1

\frac{7\cdot 6\cdot 5\cdot 4!}{3\cdot 2\cdot 1\cdot 4!}

Cancel the  common factor we get

35  possible combinations would be there.

AlexFokin [52]

Answer:

2(3x+2y) and 6x+4y

Step-by-step explanation:

If we expand all of the solutions and the expression we are trying to match, we can see which expression has all matching terms.

The expression we are matching to can be expanded to:

2(2x+4y+x-2y)

4x+8y+2x-4y

6x+4y

Solution 1: NO

2(x+5y) and 2x+12y

2x+10y and 2x + 12y

Solution 2: NO

2(x+2y) and 2x+4y

2x+4y and 2x+4y

Solution 3: YES

2(3x+2y) and 6x+4y

6x+4y and 6x+4y

Solution 4: NO

2(3x+6y) and 6x+12y

6x+12y and 6x+12y
