The school assembly had 30 students in attendance and 20% of them were first graders. how many first graders were at the assembly?

The answer is 6. 6 of them are first graders

Step-by-step explanation:

30 * .2 (20%=.20) = 6

There would be 6 first graders

Step-by-step explanation: There are 30 students

20% are first graders

So 30 = total and 20% is 1st graders

20% of 30

Which means 20%*30 = 6

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
