This data set was created from examining several ice cores drilled at Antarctica's Vostok Station in 2001. Examine the data and write about one correlation that you see. What does the correlation tell you about Earth's historic atmosphere or climate? ($ybp =$ years before present, $ppb =$ parts per billion, and ppm = parts per million)

Ana's part is bigger

Answered by Anonymous | 2024-06-10

Alrighty, let's think of it like this: You are trying to fill a box with a bunch of sports balls. You have tiny little golf balls, and you have giant bowling balls. You need to fill this same box all the way up.
If you fill it with the tiny golf balls, you are going to need a whole lot of them!
If you are putting in bowling balls, only a few of them will fit, because they are so much bigger.
When it comes to your fraction, the box is the the number 8/10. That number will not change because we are not changing the size of the box.
We are just changing what we are filling it with. Manny, can fit 8 parts, or in this case balls, into the box.
It says Ana uses fewer parts, so she cannot fit as many in as Manny.
This means that Manny would have the golf balls, since he can fit more in than Ana, who must have the bowling balls.
So which is bigger? A bowling ball or a golf ball?
A bowling ball, which is what Ana has. So Ana's part will be bigger in size.

Ana uses fewer parts to model an equivalent fraction, meaning her parts must be larger than Manny's. Manny uses 8 parts of size \ (1/10), while Ana uses fewer parts that could be \ (1/5) in size. Therefore, Ana's parts are larger than Manny's tenth-size parts.
