Answer:
9 people should get on stop 1.
Step-by-step explanation:
If i understood it correctly .
13 people on bus initially.
at first stop - 4 people get off . So 9 people should be on bus.
But few get in bus ( that is what is asked in the question - but it is not super clear to me)
after 2nd stop - there are 12 people on bus.
at 2nd stop 6 people got off.. so there were total of 18 on the bus
So if there were 9 people on bus stop by stop 1 .. so 9 people should have got in bus at stop 1 to make it equal to 18.
Only doubt i have is : if the question is asking how many got on the 2nd stop. also i was not clear what does this line means - At the first stop, four people get off and to get on.
Answer:
Step-by-step explanation:
To break down the volume even more, the base of a cylinder is pi(r)^2
Instead of V=Bh use V=pi(r)^2h (it's broken down more so it's easier to understand)
So just plug in the values to make B:
B=pi(r)^2
B= pi(8.3)^2
Answer: 20
Step-by-step explanation:
x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
The probability that no boys will be chosen is 0.2857
What is probability?
The area of arithmetic called likelihood deals with numerical representations of the chance that an incident can occur or that a press release is true.
Main Body:
Total students =22
total boys = 10
total girls =12
Now we have to chose 2 girls from 12 , so combination is used to select ,
⇒¹²C₂
Also, We have to chose 2 girls from 22 students
so it can be represented as ,
⇒²²C₂
Probability of choosing 2 girls = ¹²C₂/²²C₂
On solving this we will get = 0.2857
Hence the probability is 0.2857
