there are 25 students in mrs. venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. a new student with 8 siblings joins the class in november. what is the new class average for number of siblings? round your answer to the nearest hundredth.

Respuesta :

So, at the beginning there are a total of 25*3=75 siblings (we can assume that each of them had exactly 3 siblings, that's what average means; that we can assume this).

Now we have 25+1=26 students and the number of siblings is 75+8=83

and the average is[tex] \frac{83}{26}= 3.192[/tex], and rounded it's 3.19.
