Answer: Second option.
Step-by-step explanation:
Given the function f(x), which is:
And given the function g(x), which is:
You need to substiute the function into the function
in order to find
.
Therefore, through this procedure, you get this answer:
You can observe that this matches with the second option.
Answer:
Total number of students surveyed about their mode of transportation to school is 400.
Step-by-step explanation:
Here, given student who uses car as their mode of transport = 120 students
We have to find the total number of students who are surveyed.
Also, since complete circle represents 100% of data,
Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.
Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%
Thus, percentage of students that uses car = 100 - 70 = 30%
Thus, 30 % of total students = 120
Mathematically, 30% of x = 120
Solving for x, we get,
Thus, total number of students surveyed about their mode of transportation to school is 400.
