Question

Samantha got an answer of about 3.873 when she entered 15 on her calculator and pressed the (sqrt ) key. As usual, she stopped to think briefly about whether or not her calculator's answer was reasonable. Which of the following statements is the most likely explanation for her to believe that her calculator's answer is or is not reasonable?

It is reasonable because 3 squared is 9 while 4 squared is 16.
It is reasonable, because 15 is an odd number.
It is not reasonable, because the answer should be a whole number.
It is not reasonable, because the answer should be only slightly more than 3.

Answer 5

Let's take a look at the choices.
The second choice said that it is reasonable since it is an odd number. But we have perfect square odd number. Like 81, 9 etc.
The third choice said because the answer must be a whole number which is very impossible since we all know that 15 not a perfect square number.

But the 1st choice said that it is reasonable since 3 is sqrt of 9 and 4 is sqrt of 16. And we all know that 15 is much nearer to 16 than 18. And the last choice tells us that the answer should be slightly more than 3. Which is really not correct.

Hence the answer is the 1st choice.

Answer 6

i mean 9 to 18 there
