Answer:
1.U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
2.U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
Step-by-step explanation:
We are given that 
and 
are different sets
1.We have to construct a universe set U and non empty sets A,B and C so that above set in fact the same
Suppose U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
{2,3,4,5}
={2}
{2,3,4,5}={2}
={2}
={2}
Hence, 
2.We have to construct a universe set U and non empty sets A,B and C so that above sets are in fact different
Suppose U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
={2,3,4}
={1,2}
={1,2}
={1,2} {2,3,4}={2}
Hence, 
80$ won't be enough to pay
He would like need 6 more cents
he needs 80.06$
because
This is a permutation (without replacement) so the probability is the probability of the first event times the probability of the second event. The equation would be ((x)/16)*((x-1)/(16-1))=1/12 don't ask me how I got this I'm not even sure myself. Algebra will give you an answer of x=5 or x=-4 and there can't be -4 girls in the class so there must be 5 girls.
Answer:
Step 1: Define your variables. You should begin with a specific research question. ...
Step 2: Write your hypothesis. ...
Step 3: Design your experimental treatments. ...
Step 4: Assign your subjects to treatment groups. ...
Step 5: Measure your dependent variable.
Step-by-step explanation:
Generally, the experimental unit is the person, animal, or object that is the subject of the experiment. Experimental units receive different treatments from one another in an experiment.
