Answer:
B.
Step-by-step explanation:
Given,
The time for set up the game = minutes,
Also, the time for each level of game is minutes,
If there are l levels of games,
Then the time taken in all levels of game = <em>
</em>
Hence, the total time ( in minutes ) = Set up time + time in all level
=
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,
=
Which is the required inequality.
Option 'B' is correct.
Answer:
The probability that the result is positive is P=0.04475=4.475%.
Step-by-step explanation:
We have the events:
D: disease present
ND: disease not present
P: test positive
F: test false
Then, the information we have is:
P(D)=0.005
P(P | D)=0.99
P(P | ND)=0.04
The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).
The probability that the result is positive is P=0.04475.
