Answer:
1.
E(down) / Odd(Across) H T
H (1,-1) (-1,1)
T (-1,1) (1,-1)
2. Even doesn't have a dominant strategy as both the strategies are providing equal payoffs for pure strategy.
Answer:
A would be 54,B would be 54, C would be 65, d would be 61
Let the equation representing the function be y = -mx + c; where m is the charge per minute and c is a initial balance.
25.04 = -31m + c . . . . . (1)
19.74 = -64m + c . . . . . (2)
(1) - (2) gives: 5.3 = 33m
m = 5.3/33 = 0.16 (i.e. charge per minute is 16 cents)
From (1), 25.04 = -31(0.16) + c
25.04 = -4.96 + c
c = 25.04 + 4.96 = 30 (i.e. initial balance is $30)
Remaining credit after 85 minutes call is -85(0.16) + 30 = -13.6 + 30 = $16.40
Can you see from the graph that the spores are increasing as time is increasing? The parabolic shape is exponential growth.
Use photomath I highly recommend it
