Answer:
b ≤ 50
Step-by-step explanation:
Since no more than 400 pounds of b number of 8 pound boxes can be taken off to ensure that the plane is in balance, this can be represented by the inequality:
8b ≤ 400
b ≤ 400/8
b ≤ 50
This means that a maximum number of 50 8 pounds boxes can be taken off the plane for a 600 pound crate to be put on ensuring that the plane is in balance.
Answer:
603.40
Step-by-step explanation:
Minimum required score = Mean + ( Z-score * Standard deviation )
Given:
Mean = 500
Z score of 3 (0.03%) = 1.88
Standard deviation = 55
therefore
Minimum required score = 500 + (1.88)(55)
Minimum required score = 603.40
