Ответ:
7.6 ft, 519 lb.
snowflake:
8.2 ft, 549 lb.
519 = 7.6 m + b
549 = 8.2 m + b
- 519 = - 7.6 m - b
+
549 = 8.2 m + b
30 = 0.6 m
m = 30 : 0.6
m = 50
410 + b = 549
b = 549 - 410
b = 139
linear model:
y = 50 x + 139
jo jo: 5.8 ft, 460 lb.
y = 50 * 5.8 + 139 = 429
460 - 429 = 31 lb.
weight of dolphin jo jo differs most from the value predicted by the model.
