[Video] Q12: Based on the histogram above, of the following, which is closest to the average (arithmetic mean) number of seeds per apple?

Explanation for Question 12 From the Math (Calc) Section on the Official Sat Practice Test 1

So looking at number 12, you can see that says based on the histogram 2 above of the following, which is closest to the average of the number of 3 seeds for apple. So here, we're trying to find the average, 4 right? We can see that our total is 12 apples. 5 So this is usually a good clue, right? 6 Whenever you're trying to find the average, you need to find the total of 7 everything added together, divided by your number of numbers. 8 Right? And so here we had 12 apples. 9 So our number of numbers was going to go in. Our denominator is going 10 to be the 12th and we just need to figure out what would go 11 in our numerator. So we can see that there's three seeds with two, 12 right? So that means I have to, 13 or if I were to list out my actual numbers, 14 rather than putting them in a histogram, I would have to written three times. 15 Now, here I have five. Actually I might be looking at that backwards. 16 Yes, I am looking at that backwards. So we have two, 17 three data points, right? Cause we have two apples with three seeds. 18 So we have a three and a three. And then here we see, 19 we have four apples with five seeds. So that'd be a 5, 5, 5, 20 and five. So we can think about listing out the data points or we 21 could get a little bit more, um, 22 mathematical with it to make our lives easier and see that we can just 23 multiply our two numbers together to get the sum, 24 right? Because three plus three is six and two times three is six. 25 And we can also say five plus...
