The key purpose of splitting the dataset into training and test sets is:

a. To speed up the training process

b. To reduce the amount of labeled data needed for evaluating classifier accuracy

c. To estimate how well the learned model will generalize to new data

d. To reduce the number of features we need to consider as input to the learning

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

i think the answer is a.( -3, -1 )

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.

i'll be glad to : )
