Answer:
<h3>2kg = mass</h3>Step-by-step explanation:
<h3>What is the mass?</h3>Mass is a body of matter without definite shape.
Use the Newton's second law of motion formula.
Note:
<u>Given:</u>
- Force = 10N
- Acceleration = 5m/s
First thing you do is divide.
10/5=2
= 2kg (mass)
Therefore, the final answer is 2kg (mass).
I hope this helps, let me know if you have any questions.

Answer:
The Pearson's coefficient of correlation between the is 0.700.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
The formula to compute correlation between two variables <em>X</em> and <em>Y</em> is:
The formula to compute covariance is:
The formula to compute the variances are:
Consider the table attached below.
Compute the covariance as follows:
Thus, the covariance is 75.
Compute the variance of X and Y as follows:
Compute the correlation coefficient as follows:
Thus, the Pearson's coefficient of correlation between the is 0.700.
