Because if you ask one student from each class you are getting a more accurate representation of the classes. If you were to ask one group you'd only get their opinion
P(H)=1/2, P(1)=1/6
P(H and 1)=(1/2)(1/6)=1/12 (≈8.33%)
20 liters. If there’s 8 liters every 2 days, 8 divided by 2 is 4. 4x5 is 20 liters.
Answer:
Sorry, I only know the answer to B.
Step-by-step explanation:
The answer is 0=0, 2=5, 4=10, 6= 15. Sorry if I am late. But I hope this helps, and Have an amazing day!!
Answer:
Line QR = line BC
Step-by-step explanation:
To prove congruency using the SAS theorem, (SAS = Side Angle Side)
You obviously need 2 sides and 1 angle.
BUT
The ONE angle has to be right between the TWO sides, hence the name: side ANGLE side.
So coming to your problem:
We know angle Q = angle B. And QS=BD
We need one more SIDE. Pick side QR in triangle RQS. Is angle Q in the middle of QR and QS?
Yes it is!
Now find the corresponding side in the other triangle to QR. This is the shortest side, BC.
Check:
Is angle B in the middle of CB and BD?
Yes!!
So you can prove the congruency of these two triangle using the SAS theorem if you know that BC = QR. That’s your answer.
Hope this helped!!!!!
PS let me know if it’s correct!
