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:
Terms: 4x, -
Coefficients: 4, 
Step-by-step explanation:
The terms of an expression are the numbers and variables that are being added. In this expression 4x is being added to -
. This means that they must be the terms. The coefficients are the constants that come before a variable. A variable is an unknown number represented by a letter, in this case, x. So the coefficients are 4 and
because both these numbers are being multiplied by a variable.
