F<-2. You just subtract 0.3 to -1.7
The ratio 9:7 gives you following statement:
- Carl will win in 9 cases from 9+7=16;
- Carl will lose in 7 cases from 16.
Then the probability that Carl will lose is
![Pr(\text{Carl will lose})=\dfrac{7}{16}.](https://tex.z-dn.net/?f=Pr%28%5Ctext%7BCarl%20will%20lose%7D%29%3D%5Cdfrac%7B7%7D%7B16%7D.)
Answer: ![Pr(\text{Carl will lose})=\dfrac{7}{16}.](https://tex.z-dn.net/?f=Pr%28%5Ctext%7BCarl%20will%20lose%7D%29%3D%5Cdfrac%7B7%7D%7B16%7D.)
C is 6 because the absolute value of -19 -13 would be 19-13 which equals 6
Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
