Answer:

P(x) + q(x)

= (3x² + 5x² + 4x - 7) + (6x³ + 2x² - 9x - 5)

= 3x² + 5x² + 4x - 7 + 6x³ + 2x² - 9x - 5

= 6x³ + 10x² - 5x - 12

P(x) - q(x)

= (3x² + 5x² + 4x - 7) - (6x³ + 2x² - 9x - 5)

= 3x² + 5x² + 4x - 7 - 6x³ - 2x² + 9x + 5

= -6x³ + 6x² + 13x - 2

Answer:

The answer is " $0.90>p>0.75.$ "

Step-by-step explanation:

$\text{Cinnabar vestigial} \ \ \ \ \ \ \ \ \ \ \ 384 \ \ \ \ \ \ \ \ \ \ \ 390 \ \ \ \ \ \ \ \ \ \ \ -6 36 \ \ \ \ \ \ \ \ \ \ \ 0.092308\\\\$

Eight phenotypes were present.

Df is provided also by a number of phenotypes -1 The degree of freedom

$\to df = 8-1= 7$

For p-value 0,9, Chi-square is 2.83;

The p-value of 0.75 is 4.5. Chi-square

Chi-sqaure value is observed at 2.965.

That means 0.90>p-value>0.75.
