To determine the value that should replace the letter [tex]\( x \)[/tex] in the "Seed color" row, we need to understand what [tex]\( x \)[/tex] represents in the context of the question.
Given data:
- Total number of plants observed: 18,066
From the table:
- In the "Seed color" row, the number of yellow seeds is: 6,022
- We need to find the number of green seeds, which is represented by [tex]\( x \)[/tex].
To find [tex]\( x \)[/tex], we can use the fact that the sum of yellow seeds and green seeds must equal the total number of plants observed.
So, we set up the equation:
[tex]\[
6022 + x = 18066
\][/tex]
To isolate [tex]\( x \)[/tex], we subtract 6,022 from both sides of the equation:
[tex]\[
x = 18066 - 6022
\][/tex]
By performing the subtraction:
[tex]\[
x = 12044
\][/tex]
Therefore, the number that should replace [tex]\( x \)[/tex] in the "Seed color" row is [tex]\( 12,044 \)[/tex].
So, the correct answer is 12,044.
