Answer:
Para factorizar trinomios de la forma ax2 + bx + c, existen varias formas, a continuación se describirá una de ellas: EJEMPLO. Se multiplica y se divide el trinomio por el coeficiente del primer término. Se resuelve el producto del primero y tercer término dejando indicado el del segundo término.
1) 300miles X $0.20 = $60
2) $50 + $60 = $110
They spent $110 for the car.
Using a binomial distribution considering there's a 30% chance it will rain on any of the three days:
<span>The probability of it raining on 0 days is (1)(0.7)(0.7)(0.7) = 34.3%. </span>
<span>The probability of it raining on 1 day is (3)(0.3)(0.7)(0.7) = 44.1%. </span>
<span>The probability of it raining on 2 days is (3)(0.3)(0.3)(0.7) = 18.9%. </span>
<span>The probability of it raining on 3 days is (1)(0.3)(0.3)(0.3) = 2.7%. </span>
<span>There's a 65.7% chance that it will rain at least once over the three-day period.</span>
The answer is attached, hope this helps!
