Correct answer is the last one.
Answer:
?= 180-(75+39)=66
Step-by-step explanation:
......
Multiply 1/5 and 1/4 so that everything has a common denominator of 200.
1/5*40/40 = 40/200
1/4*50/50 = 50/200
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
