\bf f(x)=\cfrac{2x+1}{x+1}\implies \stackrel{f(x)}{0.3}=\cfrac{2x+1}{x+1}\implies 0.3(x+1)=2x+1
\\\\\\
0.3x+0.3=2x+1\implies 0.3x-2x=1-0.3\implies 0.3x-2x=0.7
\\\\\\
-1.7x=0.7\implies x=\cfrac{0.7}{-1.7}\implies x\approx -0.41176470588235294

slega [8]

Answer:

C. as likely as not

Step-by-step explanation:

The teacher makes two groups with the same number and divides the student at random. The two groups have equal size, so the chance for someone to get picked into group 1 is 100%/2= 50%. The chance for someone to get picked into group 2 will be also 100%/2= 50%

The chance to get picked to be in group 1(50%) is the same as the chance to NOT get picked into group 1(50%). The word to explain this chance will be "as likely as not".

Answer:

see explanation

Step-by-step explanation:
