Answer: D. Predictive validity
Step-by-step explanation: Predictive validity can be explained as a method of determining the degree or level of correctness of a prediction using pre-existing information or data and values obtained from the actual measurement.
In the scenario above, the researchers investigates the correlation or relationship between the predicted value obtained using a pre- admission HESI examination, high school GPA, and SAT scores and the actual grade received upon completion of the first year. This process is to analyze or determine the validity of our prediction.
Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)

Answer:
They are equal
Make them into mixed numbers
10/4 = 2 2/4 you can put this into its simplest form so 2 1/2
5/2 = 2 1/2
