Answer:
B. 39
Step-by-step explanation:
3x=117divided by 3=39
This is just about similar triangle
mn=2jl=22
mo=2lk=26
jk=2on=40
Answer:
AUB = {E1, E2, E4, E6, E7}
Step-by-step explanation:
Since we are to look for the union of the two sets, therefore we combine all the sample points that are contained in A and B without repeating any sample even if such sample occur in both sets. For example, E4 occurs in event A and B and as such will only be repeated once in the union of the two events.
AUB = {E1, E2, E4, E6, E7}
Note that the way you arrange does not matter as well.
I hope you find this solution useful?
Answer:

Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
children : adults : total
2 5 2+5 =7
We have 280 people
Divide this by 7
280/7 = 40
Multiply each number by 40
children : adults : total
2*40 5*40 7*40
80 200 280
There are 80 children and 200 adults
