Ans: 720
<span>This is equal to the number of different arrangements of three persons from a group of 10 persons </span>
Required number of ways = 10P3 = 720
OR can be solved in this way
select 3 runners (10C3 ways)
These 3 runners can be arranged in 3! ways
<span>Total = 10C3×3! = 720

Answer:
p = (0.5 , 5)
Step-by-step explanation:
D(-6 ,4) E(7 ,6)
For the line FP to be a median, the point p must have the intermediate value at x and at y between points D and E
p = (Dx + Ex)/2 , (Dy + Ey)/2
p = (-6 + 7)/2 , (4 + 6)/2
p = 1/2 , 10/2
p = (0.5 , 5)
This is because for a medium to be the point p has to be right in the middle of the other 2 vertices
Answers: a = 49
b = 10
c = 105
Answer:
Yes. It is an arithmetic sequence.
Step-by-step explanation:
The sequence would be add 5 every time.
-9 + 5 = -4
