Answer:
A n C={0,2}
Step-by-step explanation:
From the question,
A={0,1,2,3}
B={a,b,c,d}
C={0,a,2,b}
A n C means A intersection C; and by definition all the members that are common to both set A and C
Hence A n C={0,2}
This question is based on combinations
Out of 7 appetizers, 4 are to be selected, this becomes = 7C4
Out of 3 main courses, 2 are to be selected , this is = 3C2
Out of 5 desserts, 4 are to be selected, this is = 5C4
So, total ways become =
7C4 * 3C2 * 5C4
7!/4!(7-4)! * 3!/2!(3-2)! * 5!/4!(5-4)!
= 35*3*5 =525 ways
Hence, this can be done in 525 ways.
Answer:
Z = 4.5
Step-by-step explanation:
4z - 9 = 2z
4z -4z -9 = 2z -4z
-9 = -2z
-9 ÷2 = 2z ÷2
Z = 4.5
C , I took a guess so if it’s wrong sorry
No, because 2 / 2 is not 3/4
