Answer:
180th caller
Step-by-step explanation:
45 * 4 = 180
60 * 3 = 180
180 is the LCM
Answer:
rom the relation for linear regression formula, Y = b·X + a, we have ;
For car 1
ΣXY = 102780
(ΣX)² = 36
ΣX = 6
ΣY = 52390
ΣX² = 14
N = 3
b = -1000
a = 19463
Y = -1000×X + 19463
For Car 2
ΣXY = 102539.8
(ΣX)² = 36
ΣX = 6
ΣY = 52346.6
ΣX² = 14
N = 3 .
b = -1076.7
a = 19602
Y = -1076.7×X + 19602

Answer:
Step-by-step explanation:
Given that a particular detection system has a 0.83 probability of detecting a missile attack.
Also each system is independent of the other to detect missile attack.
a) the probability that a single detection system will detect an attack=![0.83](https://tex.z-dn.net/?f=0.83)
b) the probability that at least one of the systems will detect the attack given two systems= 1-Prob no system detects
=![1-(1-0.83)(1-0.83)\\\\=1-0.0289\\=0.9711](https://tex.z-dn.net/?f=1-%281-0.83%29%281-0.83%29%5C%5C%5C%5C%3D1-0.0289%5C%5C%3D0.9711)
c) If three systems are installed, the probability that at least one of the systems will detect the attack
= 1- none of the three systems detect attack
![= (1-0.17^3)\\=1-0.004913\\=0.995087](https://tex.z-dn.net/?f=%3D%20%281-0.17%5E3%29%5C%5C%3D1-0.004913%5C%5C%3D0.995087)
d) We find that probability of detecting is more if we increase the system form 1 to 2 and 2 to 3.
Hence for safety and defence purpose multiple detection system is recommended.
