1)x+1) has positive slope, it is only A or B
2) For f(x)=4 we have x≥1, so this graph should begin with black dot.
3)So answer is B
Blue dot should be empty.
Orange dot should be black.
Only three rectangles are needed, the one at the bottom and the two at the sides.
I hope this helps.
YOU'RE WELCOME :D
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:
See below.
Step-by-step explanation:
If the exponent is a/b then a is the power and b is the value of the radical.
Example: x^2/3 = ∛x². 2 is the power and 3 is the radical.
Answers:
1) 7^2/3 = ∛7²
5) √3 = 3^1/2
9) (∛27)⁴ = 27^4/3 = 3^4 = 81.
