1.) 12x^2-7x-10
2.) 10x^2+31x-14
Hello! all the probabilities will add up to 1, so just subtract each of these to find 4.
1-0.1-0.5-0.1=0.3
4 had a probability of 0.3
It would be 70*35 / 100 + 30*25 / 100
2450 /100 + 750/100
24.50 + 7.50 = 32
So, your answer is $32
The range of the answer is [-3,infinity) and {yly>=-3}
