Answer:
38:81
Step-by-step explanation:
There are a total of 81 Astronauts in the space program.
Out of these,  43  are in outer space.
We are to determine the ratio of the number of astronauts on Earth to the total number of astronauts.
Number of Astronauts on Earth = Total Number - Number in Outer Space
                                                 =81-43 = 38
Therefore:
Number of astronauts on Earth : The total number of astronauts. = 38:81
 
        
                    
             
        
        
        
The function shows that the cost of hotdogs is 1.75 and the cost of hamburger is 1.5.
<h3>How to calculate the information?</h3>
Let hotdogs = h
Let hamburger = x
The expression will be:
h + x = 3.25
h + 7x = 12.25
Subtract the functions
6x = 9
x = 1.5
Therefore, hot dogs will be:
= 3.25 - 1.5
= 1.75

Answer: 0.04854
Step-by-step explanation:
This is calculated by using the poisson distribution formula calculator. We first have to calculate the average number of success for the given hour then further calculate the poisson Probability for the question. 
Average number of customers in first four hours = (4/12) * 120 = 40.
Randomly expected number of customers in First four hours = 35 
Hence we input This randomly expected number of customers and average number of customers in our poisson calculator. 
P(x=35) = 0.04854
