Answer:
$54.20
Step-by-step explanation:
minute=m
total monthly cost = p
39.99 + .49m = p
39.99 + .49(29) =p
39.99 + 14.21 =p
54.2 =p
 
        
             
        
        
        
The probability would be 59/140 or 42.14% (rounded: 42%).
        
                    
             
        
        
        
Christine crawled:
3 ft* (3/4)= 2.25 ft.
3 ft+ 2.25 ft= 5.25 ft
We already know that 1 ft= 12 in.
5.25 ft* (12in/ 1 ft)= 63 in.
The total distance the two children crawled together is 63 in~
        
             
        
        
        
Answer:
0.918 is the probability that the sample average sediment density is at most 3.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2.80
Standard Deviation, σ = 0.85
Sample size,n = 35
We are given that the distribution of sediment density is a bell shaped distribution that is a normal distribution.
Formula:
 
Standard error due to sampling:

P(sample average sediment density is at most 3.00)
 
Calculation the value from standard normal z table, we have,  
 
0.918 is the probability that the sample average sediment density is at most 3.00
