Answer:
you must send 25 msgs to have the same cost
Step-by-step explanation:
x = n of messages
15+ (0.25x ) = 20 + (0.05x)
0.2x = 5
x = 25
Well, before you draw out the first sock, you had 60% chance of getting a white sock since six of the ten socks are white! (6/10)
So, if you were to not replace the first drawn white sock, your percentage goes to 55.5556%! This is because you now have 5/9 socks remaining in the drawer being white!
The answer is Option D. (4,2)
in this type of question , you just need to input the (x,y) , and see if the amount is correct
y - 0.75 = 1.25 (x-3)
2 - 0.75 = 1.25 ( 4 - 3)
1.25 = 1.25 (1)
1.25 = 1.25
hope this helps
