Answer:
72%
Step-by-step explanation:
A circuit contains two switches.
The first switch transmits messages correctly 80% of the time, then the probability that the message will be transmitted successfully through the first switch is
The second switch transmits messages correctly 90% of the time, then the probability that the message will be transmitted successfully through the second switch is
The probability that the message will be transmitted successfully through both switches is
that is exactly 72%
Answer:
Step-by-step explanation:
first, you have to recognize that the two angles will be the same. They are like that b/c of how they are opposites. next , b/c they are the same , set them equal to each other and then solve the equation for x ( isolate x)
29 = 4x -1
29 + 1 = 4x -1 + 1
30 = 4x
30/4 = 4x /4
7.5 = x
now to find ∠DCE just plug in x, but you also can just observe that ∠DCE is going to be 29° b/c the angle opposite of it is also.
The numbers can be arranged in 720 ways.
There are 6 people possible for the first position; 5 for the second; 4 for the third; etc. This gives us 6! = 720.
Answer:
No because she added 2 instead of 2398. She thought the 2 was separate because of the comma separating the 2 thousand. She also made a mistake by thinking she could add easily by adding 2 to 2398 to make 2400.
I'm not really a big fraction type person, but I'm sure it's 7.625
