What system was used in the early American colonies in which incarcerated individuals were required to pay for their own food and services, including wood and coal for heat?

Which statement indicates the relationship between day reporting centers and recidivism?

Which of the following is NOT considered to be a local correctional institution?

A variable force F is applied to a block, and the relationship between the force and the block’s displacement is shown in the figure. x1 = m, x2 = m, x3= 30 m, F1= N, F2= 30 N, and F3= N. The positive directions of the force and displacement are the same (toward right). Calculate the work done by the force as the block moves from position x1 to position x2. Express your answer in joules (J). 

A box with a mass of kg is acted upon by two forces, F1 = N and F2​ = N. Assuming the block moves on a frictionless surface, determine the magnitude of the box’s acceleration. Express your answer in m/s2. The view in the figure is from above.

Based on the above example of the decision tree (DT) for the regression, The predicted label in the terminal node  is (1)____________(number; 2 points). The predicted label in the terminal node  is (2)____________(number; 2 points).

A kg box is moving on a horizontal surface in the +x direction (toward the right). The coefficient of kinetic friction is . An unknown force F, parallel to the surface, is applied to the box. The velocity as a function of time is shown in the figure. Given t1 = s, t2 = s, v1 = m/s, and v3 = m/s, determine the magnitude of the force F during the time interval from t1 to t2. Express your answer in newtons.

There are two binary logit models as ‘logit’ and ‘full_logit’ models. Based on the log-likelihood function (LL), the model fit of model 1 is (1)__________ (a. better b. worse; 2 points) than model 2. Based on Akaike Information Criterion(AIC), the model fit of the model 1 is (2)__________ (a. better b. worse; 2 points) than model 2.

Let’s assume that an economist wants to measure the effect of a prime membership card on consumers’ purchase volume. The economist collects the sample and runs the linear regressions as follows: ‘new_pv’: purchase volume of a consumer (dependent variable) ‘prime_card’ : prime card member (1) or not (0). – binary dummy variable ‘age’: age of a consumer ‘income’: income of a consumer ‘prime_card: income’: interaction terms between prime_card and income variables. Based on model 1, 1 year increase in age variable will (1) _______________ (a. increase, b. decrease; 2 points) consumer purchase volumes by (2) _______________ (number; 1 point) at statistically (3) _______________(a. insignificant, b. significant 10%, c. significant 5%, d. significant 1%; 1 point).

Based on the above example of the decision tree (DT) for the binary classification (0: candy 1: wine), the predicted class in the terminal node  is (1)____________(a. candy, b. wine; 2 points), and the predicted class in the terminal node  is (2)____________(a. candy, b. wine; 2 points).
