Brian uses a linear regression to model the relationship between cricket chirp rate and temperature shown in the table.
Chirp Rate
(chirps/sec)
20
16.2
18.4
15
17
Temperature
(OF)
88.6
83.3
84.3
79.6
83.5
Using the model, he finds the predicted temperature for a chirp rate of 19 chirps per
second to be

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph.which is the residual value when x = –2? a)–2 b)–1 c)1 d)2
