Answer: p >
Step-by-step explanation:
-21p + 69 > -49p + 81
-69 -69
-21p > -49p + 12
+49p +49p
28p > 12 divide both sides by 28
p > 12/28
reduce it p> 3/7
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=
b) the probability that at least one of the systems will detect the attack given two systems= 1-Prob no system detects
=
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

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.
Answer:
FV = 60
Step-by-step explanation:
VG => 65 × 2 = 130
FH major arc=> 119 × 2 = 238
<u>FH major arc - GH = FG</u>
FG => 238 - 168 = 70
<u>VG - FG major arc = FV</u>
FV => 130 - 70 = 60
Answer: 1) If the decimal is being moved to the right, the exponent is negative. 2) It’s it’s moved to the left, the exponent is positive.
Step-by-step explanation:
fnejfkenfejdb that’s all I know that is correct.
.15 • 50 = 7.5
25.25 - 7.5 = 17.75
thus, your answer is $17.75
