Answer:
y + 51 ≥ -240
Step-by-step explanation:
20,000 + 3,000 + 400 + 30 + 6
4 + 2h < -3
2h < -7
h < -3.5
x ∈ (-∞, -3.5)
The answer would be (3,-1)
Answer:
The expected value of lateness
hours.
Step-by-step explanation:
The probability distribution of lateness is as follows:
Lateness P (Lateness)
On Time 4/5
1 Hour Late 1/10
2 Hours Late 1/20
3 Hours Late 1/20
The formula of expected value of a random variable is:

Compute the expected value of lateness as follows:


Thus, the expected value of lateness
hours.
