Well you multiply the -4 to the 9 using and you will get -36 then you divide by -6 and you will get 6 simple as that
35,725
this is because u can take the ratio 7+5+9=21 then take 150,045/21 which u get 7,145 then time 5 and u get 35,725
Answer:
20
Step-by-step explanation:
Answer:
Theoretical probability is the likeliness of an event based on all possible outcomes. Theoretically, a coin should land on heads 50 times, and tails 50 times, if you were to flip it 100 times.
Flipping it 60 times would mean theoretical probability would be it landing heads up 30 times, and tails up 30 times.
This actually happening is unlikely though, which is why we also have emperical probability.
Use quadratic formula
(-b +- (sqrt(b^2-4ac) ) / 2a
a=1
b=-8
c=41
1.
(8 + sqrt(64-4*1*41) ) / 2*1
4 + sqrt(-100) / 2
4 + 5i.......................... solution 1
2.
(8 - sqrt(64-4*1*41) ) / 2*1
4 - sqrt(-100) / 2
4 - 5i.......................... solution 2
