Semir rolls a six-sided die every morning to determine what he will have for breakfast. If he rolls
a 1 or 2, he takes time to cook himself a big breakfast. If he rolls a 3 or larger he grabs a quick
lighter breakfast. When he cooks himself a big breakfast, there is a 15% chance he will be late for
school. If he has a lighter breakfast, there is a 6% chance he will be late for school. What is the
probability Semir will be on time for school any given day?
A. 0.09
B. 0.21
C. 0.80
D. 0.91
E. 0.94
- Researchers were gathering data on alligators in an attempt to estimate an alligator’s weight from
its length. They captured 29 alligators and measured their length and weight. They created three
regression models. Each model, along with its residual plot, is shown below. y represents the
weight in pounds and x represents the length in inches.
Which statement is true?
