The number 2,■00 is missing a digit. the number rounded to the nearest thousand is 3,000. list all the possibilities for the missing digit . explain your answer

The all possible missing digits are 5, 6, 7, 8, or 9 and the number can be 2500, 2600, 2700, 2800 2900.

Step-by-step explanation:

Consider the provided number, 2,■00

The number rounded to the nearest thousand is 3,000.

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, then rounding digit rounds up by one number.

Consider the number 2 is at thousands place and we want the number rounded to the nearest thousand is 3,000.

The number on the thousands place is increased by one number.

That means the number on hundreds place should be 5, 6, 7, 8, or 9.

Thus, the all possible missing digits are 5, 6, 7, 8, or 9 and the number can be 2500, 2600, 2700, 2800 2900.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
