Hello! remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any Table, so I've chosen an exponential function that follows this rule:
Some x and y-values are given in the following table:
Let's take the average rate of change from x = 5 to x = 8:

Answer:
Option B.
Step-by-step explanation:
It is given that all of the students of Music High School are in the band, the orchestra, or both.
Students only one group = 80%
Students in both groups = 100%-80% = 20%
Students in band only = 50%
Students in band = Students in band only + Students in both groups
= 50% + 20% = 70%
Students in orchestra only = 100% - 70% = 30%
There are 119 students in the band.
Let total number of student be x.
Total number of students is 170.
We know that 30% of all students are in orchestra only.
Therefore, the correct option is B.
