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?

What model of corrections is a penal system used for youthful offenders which features indeterminate sentencing and parole, classification of incarcerated individuals, educational and vocational training, and increased privileges for positive behavior?

Jails are constitutionally mandated to make available:

Which type of jails place the correctional officers’ station within the incarcerated individuals’ living area, or pod?

In which type of jail is the issue of lack of quick response time a problem?

Which of the following types of assays can be used to determine relative quantities of either drugs, metabolites or proteins between samples? Select all that apply.

We use linear regression for inference when a dependent variable is a (1)___________ (a. continuous variable, b. discrete variable; 1 point). We use the binary logit model when a dependent variable is a (2)___________ (a. continuous variable, b. discrete variable; 1 point). Both linear regression and logit models for inference are based on (3)___________ (a. in-sample prediction, b. out-of-sample prediction; 2 points).

The spring constant of a massless spring can be determined from the force-displacement graph, which shows the force applied to the spring and the corresponding displacement. x1 = [x] m and F2 = [F] N. A person pulls the spring slowly until it is stretched by [dx] m. Determine the work done by the person to stretch the spring. Express your answer in joules.

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 = [x1] m, x2 = [x2] m, x3= 30 m, F1= [F1] N, F2= 30 N, and F3= [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 [m] kg box is moving on a horizontal surface in the +x direction (toward the right). The coefficient of kinetic friction is [mu]. 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 = [t1] s, t2 = [t2] s, v1 = [v1] m/s, and v3 = [v3] m/s, determine the magnitude of the force F during the time interval from t1 to t2. Express your answer in newtons.
