In how many ways can a music teacher arrange 24 students in 3 rows?

There are 12144 ways to arrange 24 students in rows.

Step-by-step explanation:

Since we have given that

Number of students = 24

Number of rows = 3

We need to find the number of ways to arrange the 24 students in 3 rows.

We will use "Fundamental theorem of counting":

There are 24 options for the first row.

There are 23 options for the second row.

There are 22 options for the third row.

So, Number of ways becomes

Hence, there are 12144 ways to arrange 24 students in rows.

the correct answer is 1: 2

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
