Twelve education students, in groups of four, are taking part in a student-teacher program. mark cannot be in the first group because he will be arriving late. how many ways can the instructor choose the first group of four education students? explain step by step how to get the answer.

The answer is 330

Step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: 414,377,008

step-by-step explanation:

just multiply it
