Let's organize the data you provided. It seems to describe the snowfall over time, but the exact structure of the question isn't fully clear. From what I can infer, you're asking how much snow will accumulate after certain periods of time.

The data points can be written as:

Time (hours)	Snowfall (inches)
4	8
35	7
6	12
7	14 inches
?	11 inches
?	3.5 inches
?	4.9 inches

However, a few things are unclear:

1. Are you asking for the rate of snowfall over time?
2. Are you asking for predictions of snowfall based on this data?
3. Would you like a linear model to predict snowfall based on time?

Please clarify so I can assist better.

Here are some relevant questions:

1. Should the data be analyzed for a trend (linear or other)?
2. Are the missing hours required for the remaining snowfall data?
3. Is snowfall assumed to be constant, or does it vary over time?
4. Are these real-world measurements, and would you like a realistic model?
5. Would you like to compare snowfall rates across different intervals?

Tip: In real-world models, snowfall isn't always constant. Calculating the average rate of change can give a quick estimate, but for accuracy, consider multiple intervals.
