Question:

To model spring fawn count F from adult pronghorn population A, precipitation P, and severity of the winter W, environmentalists have used the equation F = a + bA + cP + dW, where a, b, c, and d are constants that must be determined before using the equation. (Winter severity is scaled between 1 and 5, with 1 being mild and 5 being severe.) To model spring fawn count F from adult pronghorn population

Substitute the values for F, A, P, and W from the table for Years 1–4 into the equation F = a + bA + cP + dW and obtain four linear equations involving a, b, c, and d. Year Fawns Adults Precip. (in inches) Winter Severity 239 871 11.5 3 234 847 12.2 3 192 685 10.6 5 4 343 969 14.2 960 12
