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>
Answer:
2628.48 cubic inches
Step-by-step explanation:
The inflatable raft has 4500 cubic inches of air inside it when fully inflated.
The inflatable raft loses air at a rate of a decrease 6.5% each day.
Now, we have to calculate the volume of air that will be left in the raft after 8 days.
Therefore, the volume of air left in the raft after 8 days will be ![4500[1-\frac{6.5}{100} ]^{8} =2628.48](https://tex.z-dn.net/?f=4500%5B1-%5Cfrac%7B6.5%7D%7B100%7D%20%5D%5E%7B8%7D%20%3D2628.48)
cubic inches. (Answer)
There are no solutions to the given system of equations.
Hope this helps.
Answer:
30 y
Step-by-step explanation:
We need to multiply 5 by 4y and 5 by 2 y
20y + 10y = 30y
