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
It would be 8 because sit would round 9 to 10 to make the whole problem 8
Answer:
4370*10^2
437*10^3
43.7*10^4
Step-by-step explanation:
The given number is
437000
Scientific notation can be used to write the number in different ways. We can use the powers of 10 to write the given number.
First way:
The first way is:
4370*10^2
Separating the hundred from the given number
The second way:
437*10^3
Separating the 1000 from the number in the form of power of 10
The third way:
43.7*10^4
Hence scientific notation can be used for writing the number in different ways..
D=RT
313.5=R4
divide by four
313.5/4=78.375
Therefore the answer is B
