There are 12 sixth graders, 14 seventh graders,
and 7 eighth graders in a gym class. The gym
teacher randomly selects one student to collect
balls. In how many ways can choosing not a
seventh grader occur?

There are 12 sixth graders, 14 seventh graders,  and 7 eighth graders in a gym class.

The gym  teacher randomly selects one student to collect  balls, then the number of choosing that will not pick a seventh grader is:

N = number of six graders + number of eight graders = 12 + 7 = 19 (ways)

Hope this helps!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
