Hey! 2 to the power of 5 is 2 x 2 x 2 x 2 x 2 which equals 32.
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

Answer:
4.342
Step-by-step explanation:
8.1 - 3.758 = 4.342
When you are trying to find the amount of difference between two values you subtract the value less than the other and there you go, the solution!
I hope it was as simple as that and that this helped!
Answer:
y = -7
Step-by-step explanation:
To answer this question, we must first plug in -8 for x:
3(-8) + 5y = -59
-24 + 5y = -59
+24 +24
5y = -35
/5 /5
y = -7
Hope this helps :)
Answer:
1,712,304 ways
Step-by-step explanation:
This problem bothers on combination
Since we are to select 5 subjects from a pool of 48 subjects, the number of ways this can be done is expressed as;
48C5 = 48!/(48-5)!5!
48C5 = 48!/43!5!
48C5 = 48×47×46×45×44×43!/43!5!
48C5 = 48×47×46×45×44/5!
48C5 = 205,476,480/120
48C5 = 1,712,304
Hence this can be done in 1,712,304ways
