540 people can ride the wild river in 1 hour if all of the rafts are used and each raft is full
<u>Solution:</u>
Given, There are 15 rafts available for people to use on the adventure river ride.
Each raft holds 12 people.
Then, total people capacity over all rafts = 15 x 12 = 180 people.
The park runs this ride 3 times each hour.
We have to find how many people can ride the wild river in 1 hour if all of the rafts are used and each raft is full?
Then, <em>total people count who take ride = number of rides x number of people per ride
</em>
= 3 x 180 = 540
Hence, 540 people can take ride in 1 hour.
Answer:
Let X be the event of feeling secure after saving $50,000,
Given,
The probability of feeling secure after saving $50,000, p = 40 % = 0.4,
So, the probability of not feeling secure after saving $50,000, q = 1 - p = 0.6,
Since, the binomial distribution formula,

Where, 
If 8 households choose randomly,
That is, n = 8
(a) the probability of the number that say they would feel secure is exactly 5



(b) the probability of the number that say they would feel secure is more than five




(c) the probability of the number that say they would feel secure is at most five




Answer:
(0, 25) or (3, 20) or (6, 15) or (9, 10) or (15, 0)

Answer:
100.9 yards
Step-by-step explanation:
One circuit of the track is a distance of ...
C = 2πr = 2π(60 yd) = 120π yd.
At Alex's running rate, the distance covered in 20 minutes is ...
(4 yd/s)(20 min)(60 s/min) = 4800 yd
The number of circuits will be ...
(4800 yd)/(120π yd/circuit) = 40/π circuits ≈ 12.7324 circuits
The last of Alex's laps is more than half-completed, so the shortest distance to his starting point is 13 -12.7324 = 0.2676 circuits,
That distance is (0.2676 circuits)×(120π yd/circuit) ≈ 100.88 yd
The shortest distance along the track to Alex's starting point is about 100.9 yards.
_____
<em>Additional comment</em>
The exact distance is 120(13π-40) yards. The distance will vary according to your approximation for pi. If you use 3.14, this is about 98.4 yards.
If we have two numbers A&B and we know that A times B=0 then it must follow that either A=0, or B=0 (or both)
