1 answer:
The complete factor of the polynomial 625x⁸ − 1 is (25x⁴ + 1)(25x⁴ − 1). Then the correct option is A.
<h3>What is polynomial?</h3>Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Factor completely 625x⁸ − 1.
We know that
(25x⁴)² − 1²
(25x⁴ + 1)(25x⁴ − 1)
The complete factor of the polynomial 625x⁸ − 1 is (25x⁴ + 1)(25x⁴ − 1). Then the correct option is A.

<u>Answer-</u>
<em>The probability that a randomly selected recipe does not contain sugar, given that it contains salt is 22.4%</em>
<u>Solution-</u>
The given table in the link shows the relative frequencies of recipes that contains sugar and salt, or contains at least one of those ingredients, or contains neither of those ingredients.
We have to find the conditional probability that the recipe doesn't contain sugar, given that it contains salt.
We know that, the conditional probability of occurrence of A given that B occurs is,
Putting these values,
