Answer:

3/4m + 1/2f ≤ 30
f ≤ 30

Step-by-step explanation:

Math session = 45 min = 3/4 hr
French session = 30 min = 1/2 hr
Number of math sessions = m, total math hours = 3/4m
Number of French sessions = f, total French hours = 1/2f

Total hours constraint:

3/4m + 1/2f ≤ 30

Number of session constraint:

f ≤ 30

So the system is:

3/4m + 1/2f ≤ 30
f ≤ 30

Let A and B be sets with cardinal numbers , n(A) = a and n(B) = b respectively . Decide whether the statement is true or false.

olya-2409 [2.1K]

Answer:

True

Step-by-step explanation:

$A\cup B=A\cup(A-B)\\\\A\ and\ A-B\ are\ disjoint\ that\ means\ there\ is\ no\ common\ element\ in\ these\ two.\\\\n(A\cup B)=n(B\cup(A-B))\\\\n(A\cup B)=n(B)+n(A-B)\ \ \ \ \ \ \ as\ for\ disjoint\ set\ P,Q\ n(P\cup Q)=n(P)+n(Q)\\\\(n(P-Q)=n(P)-n(P\cap Q))\\\\n(AUB)=n(B)+n(A-B)\\\\n(AUB)=n(B)+n(A)-n(A\cap B)\\\\n(AUB)=n(A)+n(B)-n(A\cap B)\\\\Hence\ given\ statement\ is\ true$
