Final answer:
The mathematics question pertains to determining how many necklaces can be made from a set number of beads. After calculating, Brianna can make 20 necklaces with 8 beads each, from the remaining 160 beads after giving away 96.
Step-by-step explanation:
The subject of this question is Mathematics, and it appears to be at a Middle School level. The student is asking how many necklaces Brianna can make from her beads, assuming that she uses 8 beads for each necklace. After giving away 96 beads, Brianna is left with 256 - 96 = 160 beads. Since each necklace uses 8 beads, we divide 160 by 8 to find out how many necklaces she can make: 160 ÷ 8 = 20. Therefore, Brianna can make 20 necklaces with the remaining beads.
The graph that represents the possible numbers of necklaces Brianna can make should exhibit 20 evenly spaced points or a bar at the number 20, assuming that the x-axis is labeled with the number of necklaces and the y-axis represents the frequency.
