Answer:
c=7.17
Step-by-step explanation:
23=6c-20
43=6c
7.17=c
nCr(20, 2) = 190 ways of selecting 2 from 20
nCr(10, 1) = 10 ways of selecting 1 from 10
To find the over all probability of winning,
Calculate the Harmonic Mean (19) and divide by 2
Equivalent to
1/ (1//190 + 1/10) =9.5
So the probability is 1/9.5 = 2/19.
Answer:
3x^2+2x+8
Step-by-step explanation:
1. x^2+2x^2=3x^2
2. -3x+5x=2x
3.1+7=8
P= 500. I = 0.04. t=5. plug those numbers into the formula. So 1.04^5 and multiplying it time 500 and the final answer would be 608.33
