137.5 miles or 138 miles covered in 2.5 hours. (if that's what you're looking for)
Answer:
y = 4x - 3
Explanation:
4x – y + 6 = 9 Subtract 6 from each side
4x – y = 3 Subtract 4x rom each side
-y = -4x + 3 Multiply each side by -1
y = 4x - 3
Answer:
The Second choice y+5=-3/4(x-2
Step-by-step explanation:
4y=3x+8 solve for y so it's y=-3/4x+2
and use the slope which is -3/4
2 = x then 5 = y
you used to pass through formula and plug it in soooo it's
y+5=-3/4(x-2)
sorry if this doesn't make any sense, I'm terrible at explaining
Answer:
i aint gon lie evolution and natural selection?
Step-by-step explanation:
Answer:
The probability of winning directly is, as you calculated, 8/36, and the probability of losing directly is (1+2+1)/36=4/36.
For the remaining cases, you need to sum over all remaining rolls. Let p be the probability of rolling your initial roll, and q=6/36=1/6 the probability of rolling a 7. Then the probability of rolling your initial roll before rolling a 7 is p/(p+q), and the probability of rolling a 7 before rolling your initial roll is q/(p+q). Thus, taking into account the probability of initially rolling that roll, each roll that doesn't win or lose directly yields a contribution p2/(p+q) to your winning probability.
For p=5/36, that's
(536)25+636=2511⋅36,
and likewise 16/(10⋅36) and 9/(9⋅36) for p=4/36 and p=3/36, respectively. Each of those cases occurs twice (once above 7 and once below), so your overall winning probability is
836+236(2511+1610+99)=244495=12−7990≈12−0.007.
Step-by-step explanation:
Suppose you throw a 4 and let p(4) your winning probability. At your next roll you have a probability 3/36 of winning (you throw a 4), a probability 6/36 of losing (you throw a 7) and a probability 27/36 of repeating the whole process anew (you throw any other number). Then:
p(4)=336+2736p(4),so thatp(4)=13.
Repeat this reasoning for the other outcomes and then compute the total probability of winning as:
ptot=836+336p(4)+436p(5)+…
