Question 1 of 6
1. Question
The table above shows information about a local population of bald eagles that sustain completely on fish. The eagles are also the fish’s only area predator. Due to the depth of the local water, the eagles are only able to catch the percentage of fish listed above. Not ironically, this is also exactly equal to the fish mortality rate to maintain zero population growth for the fish. On January 1, 2019, a sudden and very temporary fish kill eliminates the entire population of fish in this area. The cause of the fish kill is immediately corrected so it can’t happen again. The park service just happens to be incredibly resourceful and is able to replace as many fish as necessary the very same day. Approximately how many fish will the park service have to immediately restock to allow the local eagle population to eventually sustain itself at 70?
Correct
The equation to solve this wordy question is (70 x 1 x 365)/0.10. The average fish weight is extraneous as the question asks for the number of fish and not their weight in pounds. You probably won’t get a question quite this wordy (we hope not!) but prepare for smaller such “walls of text” on test day.

Question 2 of 6
2. Question
A bodybuilder’s daily goal is to lift at least 9,000 pounds every day at the gym. The amount of weight lifted each time is not important as long as the total repetitions push the total weight lifted to 9,000 pounds. One day the gym is extremely crowded and the bodybuilder can only find two weights to lift. One weighs 35 pounds and the other weighs 55 pounds. Which of the following inequalities represents the bodybuilder’s daily goal where x represents the necessary number of repetitions with the 35 pound weight and y represents the necessary number of repetitions with the 55 pound weight?
Correct
The bodybuilder wants to equal or surpass the 9,000 pound goal, so answer choice B can be immediately eliminated since the equation reads “less than or equal to.” (Which only would have been correct if 9,000 had been subtracted and the other side of the equation had a value of 0. Answer choice D correctly places the x and y variables with their respective weights of 35 and 55.

3. Question
College Football Scholarship Offers for Starting High School Senior Quarterbacks
The table above summarizes the college football scholarships for starting high school senior quarterbacks in a particular state. If a starting high school senior quarterback is chosen at random, what is the probability the athlete chosen hired a personal trainer only and was offered a college football scholarship?Correct
Use your calculator to add up all 8 numbers in the table and calculate the denominator (total starting high school senior quarterbacks) as 524. The numerator if found in the table as there were 8 quarterbacks who were offered college football scholarships who hired a personal trainer only.

Question 4 of 6
4. Question
Which of the following graphs shows the strongest negative correlation between the two variables?
Correct
A and D represent positive correlations. B represents a pretty random variation. Only C shows any type of negative correlation. C did have a slightly different scale (which we don’t think you’ll see on a real SAT test question), but not enough to alter the answer.

Question 5 of 6
5. Question
The table above contains the weights of all the bulls on a particular ranch to the nearest pound. The 22,000 pound outlier is actually a clerical error. Assuming the clerical error is removed from the table, which of the following will change the most?
Correct
If you understand the concepts behind these terms, there was no need to pull out your calculator. You could see there were three values of 2,055 and removing the outlier wasn’t going to affect it. A quick eyeballing of the table shows the median and mean are around 2,000 and removing the 22,000 outlier wasn’t going to affect them much either. However, the range is poised to plummet by about 20,000 if the outlier is removed.

Question 6 of 6
6. Question
Which of the following rounds the closest to the value of x?
Correct
Answer: C
Fortunately, the right triangle equation, a2 + b2 = c2, is included in the reference section. To solve for x, you can solve for AE by calculating the square root of the sum of ED squared (81) + DA squared (484) and then multiplying that amount by 10/22. (Which also simplifies to 5/11 though the calculator makes that simplification step unnecessary.) Alternatively, x can be calculated by calculating BC as (9 x 10/22) and then calculating the square root of the sum of AB squared (100) + BC squared (16.74).Incorrect
