An investigator doesn't change the value of a  variable parameter because it changes by itself since a variable parameter is factors that change or vary throughout the experiment. Hope this answers the question. Have a nice day. Feel free to ask more questions.

Answer: Hi!

Usually you have two types of variables, the independents (parameters that you can change and modify, such as the time you left a potato in a hot oven) And dependent variables ( such as the temperature of said potato when you took it out of the oven).

The parameters in a investigation are independent variables, and you want to change them to see how the changes impact in the dependent variables, in order to describe these changes.

jekas [21]

Answer:

213 points

The y-intercept is how many points Jackson already scored, and the slope is how many points he is scoring every game.

Step-by-step explanation:

Jackson earns 28 points per game, so after 6 games, he earns 168 points (just multiply 6 by 28). He already scored 45 points, so if you add them together, he scored a total of 213 points.

The y-intercept is 45, what he already scored, and the slope is 28, how many points he scores per game.

Hope I helped!!!

On a road trip, Sara’s brother drove 47.5% of the trip, and Sara drove 80% of the remainder. If Sara drove for 4 hours and 12 mi
masha68 [24]
Let's put it all into minutes, and then solve. 4 * 60 + 12 = 252 minutes.
252 / 80 = 3.15.
3.15 * 100 = 315 = 52.5% of the trip.
315 / 52.5 = 6
6 * 100 = 600 minutes
600 / 60 = 10 hour road trip.
