(08.01 LC) Sally is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is odd} and let B = {the sum of the number cubes is divisible by 2}. List the outcomes in A ∩ B.

The cat Phillipa has become anxious. She has lost weight, and she is restless and sleepless. You are a veterinarian specializing in endocrinology. Your first determine that Phillipa has high thyroid hormone levels in her blood. Your next step is to determine whether the problem lies at the level of her hypothalamus, anterior pituitary, or thyroid gland.  Question: You discover an endocrine tumor in Phillipa’s anterior pituitary. If this tumor is causing her symptoms, which hormone levels do you expect to find in her blood, compared to in a healthy cat? (Thyrotropin-releasing hormone = TRH, thyroid-stimulating hormone = TSH).

The table shows the relationship between the number of side dishes and the total cost of the special. Restaurant Number of Side Dishes Total Cost 2 $10.25 4 $13.25 5 $14.75 8 $19.25 Which of the following graphs shows the relationship given in the table?

(08.05 MC) Alice wants to prove to her parents that listening to music while she does her homework will help her get better grades. She decides to ask 25 of her friends if they listen to music while they do their homework and what their grades are. She finds that her friends who have high grades also listen to music while they do their homework. She tells her parents that she has proven that listening to music while doing homework will cause her grades to improve. What mistake has Alice made?

(08.05 MC) A restaurant manager gives a survey to all of his customers asking them to rate the quality of the service they received. He then keeps track of how many customers return to the restaurant during the next six months. Last year, the results showed that of the customers who reported high quality service, 90% returned for additional meals. What conclusion can be drawn from this study?
