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.

Answer: 57 ft²
Step-by-step explanation:
Find the areas of the two individual rectangles and then add that up to find the area of the figure:
Rectangle A: Rectangle B:
= Length * Width = 11.5 * 3
= 7.5 * 3 = 34.5ft²
= 22.5 ft²
Area of figure:
= 22.5 + 34.5
= 57 ft²
