2/3* 3 is 2 so the answer is x=2
9x +5y= -45
put in standard form
y= mx+b
coefficient of x is the slope, b is the y intercpept
5y= -9x -45
y= -9/5 x -45
graphing will start at -45 on the y axis
from that point go down 9 to the right 5 for the slope continue and graph minimum
2 points to draw the line
hope this helps
Answer:
75 buses needed
Step-by-step explanation:
3,600 people / each bus holds 48 people = 75
The experimental research has two key advantages over correlational studies.
1. The possibility of random assignment
2. Causal connections can be assumed.
<h3>
What benefit does experimental research have over correlational research?</h3>
Correlational studies merely examine the data that already exists, whereas experimental studies give the researcher the opportunity to influence the study's factors. Researchers can make inferences about how changes in one variable affect changes in another through the use of experimental investigations.
The factors in a correlation study are out of the control of the researcher or research team. The researcher merely measures the information she discovers in the outside world. She can then determine whether changes in one are related to changes in the other, or if the two variables are correlated. In such a study, experimenters gather existing data and use statistical methods to examine it, such as economic statistics from governments. The findings of correlation studies can lead to hypotheses that can be verified through a more focused experimental one.
