100% - x
115% - 84.87
x=(100*84.87)/115=73.8
Answer:
Difference = 250 students
Step-by-step explanation:
Let the total number of students be x.
Given the following data;
% driving = 30%
% riding = 60%
% walking = 10%
Number of students driving = 375
First of all, we would determine the total number of students.
Total = 30/100 * x = 375
0.3x = 375
Total, x = 375/0.3
Total, x = 1250 students.
Next, we determine the number of students walking;
Walking = 10/100 * 1250
Walking = 12500/100
Walking = 125 students
Finally, we would determine many more students drive to school than walk to school;
Difference = 375 - 125
Difference = 250 students
Plug in the number from f(x) with the x value
For example
f(9)=(9)^2-25
81-25
F(9)=56
That’s one answer.

Mean is the average. So you add up all the numbers and divide by how many numbers there were.
Mode is the number that occurred the most.
Median is the number that is in the middle when you list the numbers from least to greatest or greatest to least.
Range is calculated when you subtract the biggest number in the group by the smallest number.
