1. No, Bo made an error on Line 3. When he pulled out x from x² - 8xy, the result should have been x(x - 8y). Instead, Bo wrote x(x - 8). It should go like this:

Line 1: x² - 10xy + 16y²
Line 2: x² - 8xy - 2xy + 16y²
Line 3: x(x - 8y) - 2y(x - 8y)

After this, we can pull out the factor (x - 8y):

Line 4: (x - 2y)(x - 8y)

2. I'm not 100% positive, but I think you would have to look at a and c in the equation y = ax² + bxy + cy². If they are prime numbers, I believe that the equation would be prime.

Answer:

The correct option is C) Both of the above.

Step-by-step explanation:

Consider the provided statement.

First understand the meaning of Confidence level.

Confidence level refers to the percentage of likelihood, or assurance, that when you draw a random sample several times, the confidence interval will contain the true population variable.

99% confidence means We are 99% sure that most of these confidence intervals contain the true parameter of the population.

Therefore, both the statement are correct.

Hence, the correct option is C) Both of the above.
