Josiah measures the lengths of different banners around the school and records the lengths in both centimeters and meters. which statement is true about the lengths of the school’s banners? the lengths in centimeters show that there is more variation in the data because the variance is 10,000 times greater than the variance of the lengths in meters. the lengths in meters show that there is less variation in the data because the variance and standard deviations are approximately equal. the lengths in both measurements have the same variation because they represent the same data in different units. the standard deviations of 99.1 centimeters and 0.991 meters are equivalent lengths. the variations of the lengths in centimeters and meters cannot be compared because the standard deviations are not equal.

Carla was trying to decide what to do saturday evening. she has $100 available to spend for the evening. she has narrowed her choices down to these events: braves game, a concert of an artist she likes, or the georgia aquarium. admission to the braves game is $25, hot dogs cost $10, sodas cost $5. the concert costs $25 for admission, $20 for a souvernir t-shirt, and $10 for a soda. the georgia aquarium has the show of a lifetime with an all you can eat and drink that costs $100. carla does not want to take any driving chances, so in addition to the cost of the aquarium, she will also need to pay for her uber/lyft, which is $15 each way. which option should carla choose if she wants to spend the least? based on that choice, what then is carla's oppotunity cost? fully explain your answer in at least one paragraph.
