4 girls and 6 boys
2(2 girls) and 3(2 boys)
₄C₂ x ₆C₂
= 6 x 15
= 90
Answer: 90 different teams
Hello from MrBillDoesMath!
Answer:
The fourth choice, b = +\- sqrt( sg + a^2)
Discussion:
s = (b^2 - a^2)/g => multiply both sides by "g"
sg = b^2 - a^2 => add a^2 to both sides
sg + a^2 = b^2 => take the square root of each side
b = +\- sqrt( sg + a^2)
which is the fourth choice.
Thank you,
MrB
I think that it would be 3/2 because you are simplifying the fractions 24/16.
Answer:
Sequence :
Rate of change : -3
Step-by-step explanation:
It is given that the sequence represents by the points (1,8), (2,4), (4,1) and (5,0.5).
We know that the represent the point (n,k). So, we have
It is clear that the above sequence is a geometric sequence because it has common ratio .
First term :
Common ratio :
The nth term of a G.P. is
Therefore, the required sequence is .
We need to find the average rate of change from n = 1 to n = 3.
Therefore, the average rate of change from n = 1 to n = 3 is -3.
