I think you get the point! Hope this helped!
Answer:
1 : 2 : 5
Step-by-step explanation:
20 : 40 : 100 ( divide each part of the ratio by 20 , the HCF of 20, 40, 100 )
= 1 : 2 : 5
Answer:
Step-by-step explanation:
Given that trainees must complete a specific task in less than 2 minutes.Consider the probability density function below for the time ittakes a trainee to complete the task.
Hence F(x) = = cumulative distributive function for x between 0 and 2.
1) the probability a trainee will complete the task inless than 1 minutes
=F(1) = 0.67-0.085 = 0.585
2. the probability that a trainee will complete the task inmore than 1 minutes
=1-F(1) = 0.415
3. the probability it will take a trainee between 0.68 minutes and 1 minutes to complete the task
=F(1)-F(0.68) =0.168704
=0.1687
4. the expected time it will take a trainee to complete thetask
=
=0.8867
5.If X represents the time it takes to complete the task, what isE(X2)? Give your answer to four decimal places.
E(x^2) =
=1.1067
6.If X represents the time it takes to complete the task, what isVar(X)
Var(x) = E(x^2)-Mean^2
= 1.106667-0.886667^2
= 0.320489
=0.3205
I am going to say C) 12
If you think he made 5 goals in 4 mins, add 4 more mins and you get 10 shoots okay then I took an estimated guess on the shoots, So it could be D as well.
