Answer:

<em>Answer: B. It is a perfect square</em>

Step-by-step explanation:

<u>Radical Expressions</u>

Melissa multiplied \sqrt{a} and \sqrt{b} and got a rational number.

We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.

We can write that product like:

\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}

If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.

Answer: B. It is a perfect square

vredina [299]

Answer:

C. One can be​ 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66

Given that the confidence interval is a term that defines a range of values with the probability to contain a population value that has an actual degree of confidence.

This is represented in a situation where population means falls in between upper and lower intervals.

Hence, in this case, the correct interpretation is option C: One can be​ 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66
