An entomologist (bug scientist) wants to determine if temperature changes how many times a cricket chirps. what is the dependent (outcome) variable?

Number of times a cricket chirps.

Explanation:

Let us use a graph to understand the function Here the entomologist wants to know the effect of temperature on the number of chirps of a cricket so, the chirps should vary with temperature. The opposite cannot be true i.e., the temperature is not dependent on the number of chirps rather the number of chirps are dependent on temperature.

So, the x axis will be represent the temperature and the y axis will represent the number of chirps.

Hence, the dependent variable will be number of times a cricket chirps i.e., the y axis.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
