The answer is Letter C - 1/2,775
The probability of choosing one of them is 2 out of 75 while the probability of choosing the other one is 1 out of 74. 74 band members, not counting the other person (you or your bother).
Computation:
P = 2 / 75 * 1 / 74
= 0.0266... * 0.01351...
= 1 / 2,775
You can also multiply 75 with 74 to get a total of 5,550 then divide it by 2 students to be selected to get 2,775. Meaning one out of 2,775 possibilities.
Answer:
t is common practise to label the vertices of a triangle with capital letters
Answer:
95+75=170 mph=speed at which the two trains are moving apart
travel time=distance/speed=374/170=2.2
How long will it take for the two trains to be 374 miles apart? 2.2 hrs
Step-by-step explanation:
Answer:
2.75
Step-by-step explanation:
to get the mean all you have to is add all the numbers up then divide by how numbers there are. so 3e is what u get when u add them up then divide by 12 and u get 2.75
Check the forward differences of the sequence.
If 
, then let 
be the sequence of first-order differences of 
. That is, for n ≥ 1,
so that 
.
Let 
be the sequence of differences of ,
and we see that this is a constant sequence, 
. In other words, is an arithmetic sequence with common difference between terms of 2. That is,
and we can solve for 
in terms of 
:
and so on down to
We solve for 
in the same way.
Then
and so on down to
