Answer:
-m²+81
Step-by-step explanation:
Hello There!
9x-m=-9m
9x9=81
mx-m=-m²
9xm=9m
9m-9m=0
we would be left with
-m²+81
Answer:
114.75
Step-by-step explanation:
- 6x3=18
- 8x10=80
- 8.5
- Add all together, you get = 229.5
- Divided by 2 you get = 114.75
Let n = total boxes (5)
Probability (p) = 1 out of 4 = 1/4 = 0.25
Probability she wins at most 1 out of 5 is p(x <=1) Which is also = p (x =0) + p(x=1)
Probability of not winning would be 0.75 ( 1-0.25)
No prizes in 5 boxes = 0.75^5
1 prize in 5 boxes = 5 x 0.25 x 0.75^4
Total probability = 0.75^5 + 5 x 0.25 x 0.75^4 = 0.63
