A. 18,066
B. 3,011
C. 207
D. 2,001


Sagot :

To determine the number that should replace the letter [tex]\( x \)[/tex] in the "Seed color" row, let's analyze the information given in the table:

1. Given Information:
- The total number of plants (for "Seed color") can be determined by some summaries provided.
- We're given that the count of yellow seeds is [tex]\( 6,022 \)[/tex].

2. Important Concept:
- The total number of plants listed for "Seed color" is [tex]\( 18,066 \)[/tex].

3. Calculation Step:
- The total count of seeds for "Seed color" is the sum of the counts of yellow seeds and green seeds.
- We need to find the count of green seeds [tex]\( x \)[/tex].

Given:
- Total number of seeds = [tex]\( 18,066 \)[/tex]
- Number of yellow seeds = [tex]\( 6,022 \)[/tex]
- We need to find [tex]\( x \)[/tex], the number of green seeds.

We can write the relationship as:
[tex]\[ \text{Total number of seeds} = \text{Yellow seeds} + \text{Green seeds} \][/tex]

Substituting the given values:
[tex]\[ 18,066 = 6,022 + x \][/tex]

To find [tex]\( x \)[/tex], we subtract the number of yellow seeds from the total:
[tex]\[ x = 18,066 - 6,022 \][/tex]

Calculation:
[tex]\[ x = 12,044 \][/tex]

Thus, the number that should replace [tex]\( x \)[/tex] in the "Seed color" row is [tex]\( 12,044 \)[/tex].
