Answer:
0.125 is the answer
Step-by-step explanation:
10% of what is 9...
0.10x = 9
x = 9/0.10
x = 90.....he has 90 all together
Answer:
Step-by-step explanation:
25.57, 123/5, 49/2, 241/10
Answer:
2.4
Step-by-step explanation:
12x2.4 = 28.8 (Area)
12+12+2.4+2.4 = 28.8 (Perimeter)
Answer:
0.8753
Step-by-step explanation:
Calculate the probability that your job will be ready before 10.01 am
Here, the parameter of an Exponential is E(X)=12
Now, to calculate the third job probability, it follows Poisson Distribution with parameter 1/λ
Therefore, E(Y) =1/12
Here, The third job will be ready for 10:01 AM, then E(Y)=61/12
Therefore, the required probability is

=1- POISSON(3,5,true)
=1-0.1246
=0.8753
