I was confused at first until I realized that you'd shared not one, not two, but three questions in one post. would you please post just one question at a time to avoid this.
I'll focus on your second question only: Solve <span>3 + |2x - 4| = 15.
Subtr. 3 from both sides. Result: |2x - 4| = 12
Divide all terms by 2, to reduce: |x - 2| = 6
Case 1: x-2 is already +, so we don't need | |:
x - 2 = 6 => x = 8 (first answer)
Case 2: x-2 is negative, so |2x-4| = -(2x-4) = 6
Then -2x + 8 = 6. Subtr. 8 from both sides: -2x = -2
Div both sides by -2: x = 1 (second answer)
Be sure to check these results by subst. them into the original equation.
Please post your other questions separately. Thanks and good luck!

Answer: nonresponse bias
Step-by-step explanation:
According to the information obtained, we can say that it is a non-response bias, since the sample obtained to extrapolate the result was not homogeneous, so these biases arise when the type of response to the non-response is affected in a social experiment. meet a standard among the population muesta¡ra.
Cognitive biases are found in ideas that make us partial. These thoughts, along with certain external circumstances, create what are known as response biases.
