Answer:
1. Randomly divide the available set of observations into two
parts, a training set and a validation set or hold-out set.
2. Fit the model on the training set.
3. Use the resulting fitted model to predict the responses for the
observations in the validation set.
4. The resulting validation set error rate is typically assessed using
the MSE in the case of a quantitative response. This provides
an estimate of the test error rate.
Answer:
If you have to share 2 by 3 equally then that is saying divide, when you divide you get .6666 but if you turn it into a fraction it 2 over 3

Answer:
Distance swam by Sonya in 3 weeks = 19740 m
Step-by-step explanation:
To practice for a competition, Sonya swam 0.94 kilometer in the pool each day for 3 weeks.
Number of days in 1 week = 7
Number of weeks she swam = 3
Total number of days she swam = 3 x 7 = 21 days
Distance swam per day = 0.94 km
Total distance swam = Total number of days she swam x Distance swam per day
Total distance swam = 21 x 0.94 = 19.74 km = 19.74 x 1000 m = 19740 m
Distance swam by Sonya in 3 weeks = 19740 m
