Answer:
Step-by-step explanation:
Domain: Students enrolled in a school year
Range: The english course a students takes
g is a function because each student, or each element of the domain, corresponds to one element of the range
<span>The common denominator of the two fractions is: 8
</span><span>1/4 = (1*2)/(2*4) = 2/82/8 = (1*2)/(1*8) = 2/8
<span>Fractions adjusted to a common denominator1/4 + 2/8 = 2/8 + 2/82/8 + 2/8 = (2+2)/8(2+2)/8 = 4/84/8 = 1/2
The answer is 1/2.

Answer:
All we have to find the fraction of students who preferred green and go from there.
Subtracting blue and red out of the all students,
1- (1/8+1/4)
1- 3/8
5/8 is the remaining students, in order to find 3/5 of the remaining students, we multiply by 3/5
5/8(2/5) = 3/8
3/8 preferred green, which was 15 students. In order to get 100% of the whole population (1), we multiply by 8/3:
15(8/3) = 40
40 students were surveyed in total.

Answer:
B
Step-by-step explanation:
In the set of ordered pairs {(3, 4), (4, 3), (4, 4), (5, 2)}, the domain is the set of the first number in every pair (those are the x-coordinates): {3, 4, 5}.
He made $120.
You divide 1,320 by 22. That gives you 60. Then you times 60 by 2(which equals 120) because 60 represents the packets and he made 2 dollars per packet.
Mathematically the steps look like this:
1,320/22
=60
60(2) or 60 x 2
= 120
so $120
