[Video] Q10: What is the life expectancy, in years, of the animal that has the longest gestation period?

Explanation for Question 10 From the Math (Calc) Section on the Official Sat Practice Test 4

Now for number 10, we're given a graph, right? 2 And so this is a curator from the wildlife society that created the scatter 3 plot, and it shows the relationship between lifespan and gestation 4 period and gestation period is just the amount of time that a, 5 you know, a baby spends in the womb for, 6 with his mother, um, before it's actually given birth to. 7 Um, but you don't actually need to know what this is for the graph 8 to make sense, and to be able to do the questions. 9 So keep that in mind, don't get caught up in the vocab here. 10 And then number 10 asks us what is the life expectancy, 11 right. So we're looking for something on the Y axis, 12 the L E um, of an animal that has the longest gestation 13 period. Right? So question one would be what is the longest gestation period? 14 So we look along this axis and we see the, 15 the point that's furthest to the right is right here and make it a 16 little bit bigger. And of course, 17 um, let's see here. Yeah. We're not interested in a, 18 B, C, and D. Right now we can look at any point and we 19 need to know what the life expectancy is at that point, 20 right? With the longest gestation period. Now, 21 if we brought, bring that over to the Y axis, 22 we see that it said about three, which means that our answer choice, 23 the 10 is going to be a three.
