60 meters
4 seconds
To find the unit rate, divide the distance by the time.
60/4=15meters per second= 15m/s
Answer:
0.362
Step-by-step explanation:
When drawing randomly from the 1st and 2nd urn, 4 case scenarios may happen:
- Red ball is drawn from the 1st urn with a probability of 9/10, red ball is drawn from the 2st urn with a probability of 1/6. The probability of this case to happen is (9/10)*(1/6) = 9/60 = 3/20 or 0.15. The probability that a ball drawn randomly from the third urn is blue given this scenario is (1 blue + 5 blue)/(8 red + 1 blue + 5 blue) = 6/14 = 3/7.
- Red ball is drawn from the 1st urn with a probability of 9/10, blue ball is drawn from the 2nd urn with a probability of 5/6. The probability of this event to happen is (9/10)*(5/6) = 45/60 = 3/4 or 0.75. The probability that a ball drawn randomly from the third urn is blue given this scenario is (1 blue + 4 blue)/(8 red + 1 blue + 1 red + 4 blue) = 5/14
- Blue ball is drawn from the 1st urn with a probability of 1/10, blue ball is drawn from the 2nd urn with a probability of 5/6. The probability of this event to happen is (1/10)*(5/6) = 5/60 = 1/12. The probability that a ball drawn randomly from the third urn is blue given this scenario is (4 blue)/(9 red + 1 red + 4 blue) = 4/14 = 2/7
- Blue ball is drawn from the 1st urn with a probability of 1/10, red ball is drawn from the 2st urn with a probability of 1/6. The probability of this event to happen is (1/10)*(1/6) = 1/60. The probability that a ball drawn randomly from the third urn is blue given this scenario is (5 blue)/(9 red + 5 blue) = 5/14.
Overall, the total probability that a ball drawn randomly from the third urn is blue is the sum of product of each scenario to happen with their respective given probability
P = 0.15(3/7) + 0.75(5/14) + (1/12)*(2/7) + (1/60)*(5/14) = 0.362
The airplane’s altitude was 400 feet at 8:00 a.m. is the best describes
the meaning of the statement h(0)=400 ⇒ answer a
Step-by-step explanation:
The altitude of an airplane is described by a certain function h ,
where h(t) is the altitude in feet of the airplane t minutes after
8:00 a.m.
That means:
1. The altitude of the airplane can be calculated by using this function
at any time after 8:00 a.m.
2. At 8.00 a.m. the value of t = 0
3. h(0) is the initial altitude of the airplane
∵ The altitude of the airplane h at any time t after 8:00 a.m. can be
calculated from the function h(t)
∵ At 8:00 a.m. t = 0
∵ h(0) = 400
∴ The altitude of the airplane at t = 0 is 400
∴ The initial altitude of the airplane is 400
The airplane’s altitude was 400 feet at 8:00 a.m.
