Answer :
To find what percentage 143 samples is out of 390, you can follow these steps:
Understand the Formula:
The formula to find the percentage is given by:
[tex]\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100[/tex]
Here, the 'Part' is 143 samples, and the 'Whole' is 390.
Substitute the Values:
Plug the given numbers into the formula:
[tex]\text{Percentage} = \left( \frac{143}{390} \right) \times 100[/tex]
Perform the Calculation:
First, calculate the fraction:
[tex]\frac{143}{390} \approx 0.3666667[/tex]
Then, multiply by 100 to convert it to a percentage:
[tex]0.3666667 \times 100 \approx 36.67[/tex]
Conclusion:
Therefore, 143 samples out of 390 is approximately [tex]36.67\%[/tex].
This percentage tells you how much of the whole is represented by the 143 samples, which can be useful in different scenarios, like analyzing survey results, statistical data, or simply understanding part-to-whole relationships.
