Answer:

Number of minutes Denzel still has to practice after x days, N(x) = 210 - 30x

Step-by-step explanation:

Denzel must practice piano for 210 minutes each week.

Total practice needed = 210 minutes

Total minutes practicing per day = 30 minutes

Let x be the number of days practiced

Total minutes practices after n days = 30x

Total remaining minutes = 210 - 30x

Number of minutes Denzel still has to practice after x days, N(x) = 210 - 30x

What I mean by that is that the United Stated as .151% of its people with hearing problems, and .093% with vision problems. So really adding them together just mixes it saying that .244% of people in the united states have either a vision or a hearing problem.

It doesn’t make it any more or any less people by adding them together. Therefore it’s not any more or any less probable to pick one or the other.

Hopes this helps.
