F(x)=9x^2 <br><br> g(x)= sqrt 12-x/3<br><br> (f o g)(-4)
Slav-nsk [51]

f(x)=9x^2 \\ g(x)=\frac{\sqrt{12-x}}{3} \\ So,first step is to write (fog)(-4)) =f[g(-4)] \\

Now we start from inner paranthesis ,we need to first find value of g(-4) =\frac{\sqrt{12-(-4)}}{3}\\ =\frac{\sqrt{12+4}}{3}\\&#10;=\frac{\sqrt{16}}{3}\\&#10;=\frac{4}{3}\\&#10;(fog)(-4)) =f[g(-4)] =f(\frac{4}{3}) =9(4/3)^{2} =9*(16/9) =144/9 =16

Based on this data, what is a reasonable estimate of the probability that Roger runs less than 5 km in his next tennis match?
defon

Answer:

5/13 for Todd running next day if this helps?

I counted the days and then counted 13 was the total so it is 5/13

Step-by-step explanation:

Days = 2,+3,+3,+ 5 = 13

13= 5/13 = probability

13 = 8:5 = ratio

5/13 was the probability of the results reoccurring same as day 5

Just as results being under 3km would only be 2/13
