First, it would be helpful to find out how many teachers there are at the school.
2470 students x (1 teacher/26 students)=95 teachers
To find the number of teachers needed, just use the ideal ratio:
2470 students x (1 teacher/19 students)=130 teachers
So to reduce this ratio to 19:1, the school needs 130 teachers. To know how many new teachers the school needs, just subtract the ideal from the current amount.
130-95=35 new teachers needed
The range of the function f(x) = |x| is [0,∞)
<h3>How to determine the range?</h3>
The function is given as:
f(x) = |x|
The above is the parent equation of an absolute value function.
The above function cannot output any negative value.
This means that:
ƒ(x) >= 0
As an interval notation, we have:
[0,∞)
Hence, the range of the function f(x) = |x| is [0,∞)
