What number should replace the letter [tex]x[/tex] in the "Seed color" row?

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



Answer :

To determine the number that should replace the letter [tex]\( x \)[/tex] in the "Seed color" row, let's follow these steps:

1. Identify Total Plants for Seed Color:
The total number of plants considered for the seed color trait is given as 18,066.

2. Determine the Number of Yellow Seed Plants:
The number of plants with yellow seeds is provided as 6,022.

3. Calculate the Number of Green Seed Plants:
To find the number of green seed plants, we need to subtract the number of yellow seed plants from the total number of plants.

[tex]\[ \text{Number of green seed plants} = \text{Total number of plants} - \text{Number of yellow seed plants} \][/tex]

4. Substitute the Values:
Substituting the given numbers:

[tex]\[ \text{Number of green seed plants} = 18{,}066 - 6{,}022 \][/tex]

5. Perform the Subtraction:
By performing the subtraction:

[tex]\[ 18{,}066 - 6{,}022 = 12{,}044 \][/tex]

6. Conclusion:
The number that should replace the letter [tex]\( x \)[/tex] in the "Seed color" row is 12,044.

Therefore, the number that should replace [tex]\( x \)[/tex] is 12,044.

The correct answer is: 12,044.
