Question

. Roger uses his truck to plow parking lots when it snows. He wants to find a model to predict the number of service calls he can expect to receive based on how much snow falls during a storm. Snow Plow Service Based on the collected data shown in the scatterplot, he uses the linear model . According to this model, c(s)=0.8s+0.29about how many service calls will Roger have in the next snow storm if 4.7 inches of snow fall? Round to the nearest tenth if necessary

Answer 1

4.1 calls

Explanation:

The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:

`c(s)=0.8s+0.29`

Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:

`c(4.7)=0.8*4.7+0.29\\c(4.7)=4.05\ calls`

Rounding to the nearest tenth, Roger will get about 4.1 calls.
