We can see from Dr. Aguilera's findings that high levels of anxiety are associated with poor academic performance. However, the number of hours of sleep has little bearing on how well or poorly a student does in class.
The confounding variable is important to avoid obstacles to the measurement
<h3>How to illustrate the information?</h3>
Dr. Aguilera discovered a strong link between anxiety and academic achievement. Additionally, this number is negative, indicating a negative correlation between the two variables. According to this negative correlation, the value of the other variable decreases as the value of the first variable increases. Therefore, academic performance declines when anxiety levels rise.
The term "correlation" describes the connection between two variables. In other words, if the correction equals 0, there is no correlation between the two variables. The relationship between sleep duration and academic performance was zero. This indicates that these factors are unrelated and have no bearing on one another.
The Cohort effect is crucial to avoid obstacles to the measurement and research methodologies used, nevertheless.

sorry but don't know the answer
but can you talk to me sorry
Answer:
Explanation:
The speed of the ball in meters per second is
Where t denotes the number of seconds since the ball has been thrown and 
is the initial speed of the ball. Then:
If the ball travels 25 meters during the first 2 seconds after it is thrown, what was the initial speed of the ball
Also, for constant acceleration motion, the average velocity is equal to the sum of final and initial velocities divided by 2 and to the distance divided by the time:
Where you know:
Substituting (the units are ommited in the equationn, but added at end of the answer):
Thus, you have a system of equations:
Substituting the second into the first:
Answer:
it is well i think it is The Market Revolution was characterized by a shift away from local or regional markets to national markets.
The agricultural explosion in the South and West and the textile boom in the North strengthened the economy in complementary ways.
Eli Whitney ‘s cotton gin and pioneering work with metal mechanical parts contributed greatly to industrialization.
Large-scale domestic manufacturing, concentrated in the North, decreased dependence on foreign imports and resulted in an increase in wage labor.
The power of the federal government grew under Henry Clay ‘s American System, which led to many improvements in the form of expanded roadways and canal systems.
The rapid development and westward expansion during the Market Revolution resulted in land speculation which caused economic boom and bust.
