A is the correct answer. ☺️
<span>-8a^3 b + 3a^2 b^2 - 5 + 2 + 5a^2 b^2 + 3a^3 b + 7 - 9a^2 b^2
= </span>-5a^3 b - a^2 b^2 + 4
answer is
<span>C.) -5a3b - a2b2 + 4</span>
Since the sample size is too small (n = 9, which is less than 10) we cannot use the normal model to describe the entire population.
Therefore, we expect the sample mean to be different from the population mean.
Answer:
Yes, the last 2 are indeed correct :)
Step-by-step explanation:
