Answer:
48 liters
Step-by-step explanation:
First container = x
Second container has twice as much oil.
Second container = 2x
13 liters of oil was used from first container.
x - 13
7 liters of oil was used from the second container.
2x - 7
Second container has 3 times more oil than the first one.
2x - 7 = 3(x - 13)
x - 7 = 3(x - 13)
x - 7 = 3x - 39
2x = 32
x = 16
First container = 16 liters
second container = 16 x 2 = 32 liters
Total = 16 + 32 = 48 liters
Answer:

Answer:
C. the life of Supplier B's tires is more predictable than the life of Supplier A's tires.
Step-by-step explanation:
A: The distributions have the same mean, but different standard deviation. They are not the same distribution.
B: The distributions have the same mean, which means on average the tire lifetimes are the same from both suppliers.
C: A smaller standard deviation means values tend to be closer to the mean, hence more predictable. <em>Supplier B's tires have a more predictable life</em>.
D: "Dispersion" is another way to describe the measure provided by standard deviation. Supplier B's tires have a lower tire life dispersion.
