Answer:
39
Step-by-step explanation:
To find the intervals you will need to find the lowest and highest numbers, in this case, it would be 1 and 35. A general rule would be 5-7 intervals, I will use 5.
Here are the intervals with the number of people that were in each:
1-7 (9)
8-14 (14)
15-21 (8)
22-28 (3)
29-35 (5)
14+9+8+3+5=39

Answer:
4a/3
Step-by-step explanation:
7-3 is 4, and the over indicates this will be the numerator.
4a-a simplifies into 3a.
Now, putting together the expression:
4/3a or 4a/3 (If it needs to be rationalised)
<span>(-5y^3 - 7y) + (7y^3 + 8y +9)
</span>
-5y^3+7y^3-7y+8y+9 <---- Group like terms
-5y^3+7y^3+y+9 <---- Add similar elements
Answer: 2y^3+y+9
Read it carefully as it may look confusing with the symbols.
