Firstly we need to realize that 17/25 is as much as 68/100 (because 4 * 17 = 68 and 4 * 25 = 100). Now we can write it as a decimal of 0.68.
0.68 is a terminate decimal because there is no other digit than 0 we can add on its right hand side.
Answer:
g^-1(x)=1/4x+1/10
Step-by-step explanation:
y=4x-2/5
x=4y-2/5
4y-2/5=x
20y-2=5x
20y=5x+2
y=1/4x+1/10
g^-1(x)=1/4x+1/10
Mean = 72
First round = 72-3 = 69
Second round = 72-1 = 71
Third round = 76
Explanation:
Total score = 72*3 = 216
69+71+x = 216
140+x = 216
x = 76
Heres the formula and steps
