Answer:
Step-by-step explanation:
multiply each variable's exponent by 2
(5x^2y^3)^2=5^2x^(2*2)y^(3*2)
simplify
5^2x^(2*2)y^(3*2)=25x^4y^6
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.
This has to do with ratios. If the current width is 8 inches and he wants to have it 35in, you must multiply the length by the same amount to keep it proportional.
