Kerri said that the product of 3.93 and 0.07 would be about 4 and would have two decimal places. Is she correct?
oee [108]

Answer:

No.

Step-by-step explanation:

This type of problem is actually a trick problem. The question indicates that the PRODUCT of 3.93 and 0.07 would be about 4. The question is referring to the answer of the two values Multiplied to each other.

To visualize the question, we have:

3.93 x 0.07

This would give us:

0.2751

Kerri would be correct if she was looking for the SUM of the two values.

This would be:

3.93 + 0.07

This would give us:

4

Therefore in trick problems like this ones, it is better to look at what exactly is being asked.

Which table represents a function?
natta225 [31]

A function must have one y-value for any given x-value.

Usually, if you see the same x-value in the x-column more than once, that's not going to be a function, because that usuall makes a single x-value pair with more than one y-value.

This would be NOT be a function, because x-value of 3 is paired with two different y-values.

<u> x  |  y</u>

3    7

4    8

3    9

6    7

Can you identify the function?
