Kim surveyed 80 students at her school and found that 0.65 of the students she surveyed said their favorite class is math. another 15% of the students she surveyed reported that their favorite class is science. how many more students in the survey prefer math over science? 12 15 28 40

The answer is 40

Step-by-step explanation:

I got it right in the test. Hope this helps :)

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

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!
