Answer:
Total Amount of money = £4800
Step-by-step explanation:
Let the shares of Dan, Ellen and Fred be 4x, 7x and 9x respectively.
According to the given information:
Amount received by Ellen = Amount received by Dan + £720
7x = 4x+720
7x-4x=720
3x = 720
x = 720/3
x = £240
now,
4x = 4*240 = £960
7x = 7*240 = £1680
9x = 9*240 = £2160
Total Amount = £960 + £1680 + £2160
Total Amount = £4800
Answer:
a) 0.03
b) 0.0004
c) 0.0001
Step-by-step explanation:
Probability that the sensor reports what is going on accurately = 0.97
Probability that the sensor gives a false alarm = 0.02
Probability that the sensor gives a miss = 0.01
(a) Probability that the sensor reports what is going on accurately = 0.97
Probability that the sensor will give incorrect report = 1 - 0.97 = 0.03
It could also be evaluated as the probability that the sensor gives either a false alarm or gives a miss = 0.02 + 0.01 = 0.03.
b) Probability of false alarms on one sensor = 0.02
Since the two sensors are independent of each other,
The probability that the reactor will be shut down because of simultaneous false alarms by both the first and second sensors
= 0.02 × 0.02 = 0.0004
c) Probability of a miss with one sensor = 0.01
Since the two sensors are independent of each other,
The the new probability that excessive radiation will be missed simultaneously by both the first and second sensors
= 0.01 × 0.01 = 0.0001

12 + 0.35X = 20.05
12 + 0.35X - 12 = 20.05 - 12
0.35X = 8.05
0.35X/0.35 = 8.05/0.35
X = 23
Hope this helps!!
