Answer:
84 points
y= 100-2x where y= total score (0 through 100) and x= # of questions wrong (0 through 50)
Step-by-step explanation:
100- 2(8) = y
100-16 = y
84=y
Since each question (x) is worth two points (2) we have to multiply each wrong question by two (2x). And then since we're deducting point from the possible points (100) we have to subtract (100-2x)

Answer:
chancing for wining is 54%.
Step-by-step explanation:
possible outcomes can be given as
HHH *
HHM *
HMH
MHH *
HMM
MHM
MMH
MMM
Out of those, only 3 will have the participant win the game:
HHH, HHM, MHH.
Probability (HHH) + Probability (HHM) + Probability (MHH)
since attempts are independant.
Probability (HHH) = 0.9 *0.4 *0.9 = 0.324
Probability (HHM) = 0.9 *0.4 *0.3 = 0.108
Probability (MHH) = 0.3 *0.4 *0.9 = 0.108
Add them up and get = (0.324+ 0.108+0.108) = 0.54
hence, chancing for wining is 54%.
Answer: 
Step-by-step explanation:
You can reduce the fractions, then:
Rewrite them as following:
If you subtract the first number and the second number, you obtain:
If you subtract the second number and the second number, you obtain:
Therefore, you must subtract 
and to obtain the number asked. Then, this is:
