Step-by-step explanation:
3x^2-(24+9)x+72=0
3x^2-9x-24x+72=0
3X(x-3)+24(x-3)=0
(x-3)(3x+24)=0
Answer:
1, 2, 3, 5, 6, 10, 15, 30.
Let us compute first the probability of ending up an odd number when rolling a dice. A dice has faces with numbers 1 up to 6. The odd numbers within that is 3 (1, 3 and 5). Therefore, each dice has a probability of 3/6 or 1/2. Then, you use the repeated trials formula:
Probability = n!/r!(n-r)! * p^r * q^(n-r), where n is the number of tries (n=6), r is the number tries where you get an even number (r=0), p is the probability of having an even face and q is the probability of having an odd face.
Probability = 6!/0!(6!) * (1/2)^0 * (1/2)^6
Probability = 1/64
Therefore, the probability is 1/64 or 1.56%.

The distance a wheel traveled can be determined by using the circumference. The circumference of the wheel is pi meters. (formula is pi * diameter)
So if there were 8000 rotations, then the bus traveled 8000pi meters.
