a LINEar function has well, the graph of a straight line, so this isn't that.
is it a relation? well, yes, because the y-value correlates with the x-value, so one depends or relates to the other.
is it a non-linear function? well, a function has to pass the <u>vertical line test</u>, meaning if we draw vertical lines they must touch the graph only once on their way down.... and in this case it seems they do, so it is non-linear clearly, and it's also a function.
Answer:
75 Arrangements
Step-by-step explanation:
Girl can secure 1st & 3rd, boy can secure 2nd position in : 6 x 5 x 5 = 150 ways ; As :
- 1st position holder can be chosen in 6 ways (among 6 girls)
- 2nd position holder can be chosen in 5 ways (among 5 boys)
- 3rd position holder can be chosen in ( among 5 remaining girls)
The arrangement of first, second & third :
It is same : If Girl G1 gets first rank & Girl G2 gets third rank, is same as ; Girl G1 gets third rank & Girl G2 gets first rank. So, two are considered the same group. Hence, number of arrangements are 150 / 2 = 75 arrangements.
