Answer:
C. 101 - 5(n - 1)
Step-by-step explanation:
d = (26 - 71)/(16 - 7)
d = -45/9
d = -5
a7 = a1 + (7-1)(-5)
71 = a1 - 30
a1 = 101
an = 101 + (n - 1)(-5)
an = 101 - 5(n - 1)
 
        
                    
             
        
        
        
Answer:
Rational
Step-by-step explanation:
Because it's an actual number that you can graph where irrational would be is if it would be a number that like pie or something where it just goes on and on
 
        
                    
             
        
        
        
Answer:
Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.
Step-by-step explanation:
The formula for the probability of an exponential distribution is:
P(x < b) = 1 - e^(b/3)
Using the complement rule, we can determine the probability of a customer having to wait more than 10 minutes, by:
p = P(x > 10) 
   = 1 - P(x < 10)
   = 1 - (1 - e^(-10/10) )
   = e⁻¹
   = 0.3679
The z-score is the difference in sample size and the population mean, divided by the standard deviation:
z = (p' - p) / √[p(1 - p) / n]
   = (0.5 - 0.3679) / √[0.3679(1 - 0.3679) / 100)]
   = 2.7393
Therefore, using the probability table, you find that the corresponding probability is:
P(p' ≥ 0.5) = P(z > 2.7393)
<em>P(p' ≥ 0.5) = 0.0031</em>
<em></em>
Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.
 
        
             
        
        
        
Answer:
W = O/U 
Step-by-step explanation:
U/1 = O/W 
WU=O
W = O/U
