Answer:
2.4
Step-by-step explanation:
Answer:
Part A:

x is a binomial Random Variable.
Part B:
Value of p=0.8
Value of n=20
Part C:
P(X=15)=0.17456
Part D:
P(X≥15)=0.80417
Part E:
E(x)=16
E(x) tells us that out of 20 tracks the SBIRS will detect from 16 tracks.
Step-by-step explanation:
Part A:
Binomial Distribution is used because the number of tracks and the probability to find the intruding object is constant for all tracks
It means:

x is a binomial Random Variable.
Part B:
Value of p=0.8
Value of n=20
Part C:
x=15

By solving above Expression:
P(X=15)=0.17456
Part D:
P(X≥15)=P(X=15)+P(X=17)+P(X=16)+P(X=18)+P(X=19)+P(X=20)

P(X=15)=0.17456



Now, Adding Probabilities:

P(X≥15)=0.80417
Part E:
Mean Distribution:
E(x)=n*p
E(x)=20*0.8
E(x)=16
E(x) tells us that out of 20 tracks the SBIRS will detect from 16 tracks.
Answer:
angle ABE = angle CDE because of the alternate interior angles theorem
Answer:
33,750,000 pounds of animals were processed during 5 days.
Step-by-step explanation:
If the average animal weight is 1350 lbs and 5,000 beef are slaughtered in one day, the total amount for one day would be: (1350)(5000) = 6,750,000 lbs.
Now we need to multiply this number by five since we want to know the total of pounds of animals processed during 5 days.
6,750,000 (5) = 33,750,000 pounds of animals.
Answer:
20
Step-by-step explanation:
An angle bisector cuts an angle into two equal parts. So m∠ACE = m∠ECB.
m∠ACE = m∠ECB
2x − 15 = x + 5
x = 20
