Explanation for Question 3 From the Math (Calc) Section on the 2019 May Sat
So question three asks for an adult crocodile with a headline of 30 2 centimeters, which of the following is closest to the body length in centimeters 3 predicted by the line of best fit. So it's asking us when the hand 4 length is 30 centimeters, what does the line of best fit predict that 5 the body length will be? So to find this out, 6 we can just scroll up and look at this graph here, 7 go to where it says 37 meters on the access axis, 8 that's here and find what is the body length, 9 according to the line of best fit. And you can see it's somewhere, 10 uh, below two 50 above 200. 11 So let's go back to our answer choices. 12 And we say the only answer choice that's above 200 and below two 50 13 is two 15. So that's the correct answer.
