Answer:
a) 0.778
b) 0.9222
c) 0.6826
d) 0.3174
e) 2 drivers
Step-by-step explanation:
Given:
Sample size, n = 5
P = 40% = 0.4
a) Probability that none of the drivers shows evidence of intoxication.



 
 
b) Probability that at least one of the drivers shows evidence of intoxication would be:
P(X ≥ 1) = 1 - P(X < 1)
 
 
 
 
 
 
 
 
c) The probability that at most two of the drivers show evidence of intoxication. 
P(x≤2) = P(X = 0) + P(X = 1) + P(X = 2)
 
 
 
 
d) Probability that more than two of the drivers show evidence of intoxication.
P(x>2) = 1 - P(X ≤ 2)
![= 1 - [^5C_0  (0.4)^0  (0.6)^5 + ^5C_1  (0.4)^1  (0.6)^4 + ^5C_2 * (0.4)^2  (0.6)^3]](https://tex.z-dn.net/?f=%20%20%3D%201%20-%20%5B%5E5C_0%20%20%280.4%29%5E0%20%20%280.6%29%5E5%20%2B%20%5E5C_1%20%20%280.4%29%5E1%20%20%280.6%29%5E4%20%2B%20%5E5C_2%20%2A%20%280.4%29%5E2%20%20%280.6%29%5E3%5D%20) 
 
 
 
 
 
e) Expected number of intoxicated drivers. 
To find this, use:
Sample size multiplied by sample proportion
n * p
= 5 * 0.40
= 2
Expected number of intoxicated drivers would be 2
 
        
             
        
        
        
Answer:
17.83
Step-by-step explanation:
d = r*t
d = 41 miles
t = 2.3 hours
r = ??
d = rt            Substitute
41 = r * 2.3   Divide by 2.3
41 / 2.3 = r   Switch sides
r = 41/2.3 
r = 17.83 mph  Answer
 
        
             
        
        
        
 
Tn=n²+3
 
from 4 to 7....the difference is 3, then from 7 to 12 the difference is 5 and from 12 to 19 the difference is 7
therefore we constantly add 2 to the difference 
 
        
             
        
        
        
More people have grown up or more people have found jobs
Hope this helps....

Answer: 48÷4 = g
Step-by-step explanation:
Here is the complete question:
Dylan scored a total of 48 points in first 4 games of the basketball season. Which equation can be used to find g, the average number of points he scores per game?
a. 48÷4=g
b. 4÷48=g
c. g÷4=g
d. 4÷g=48
The average number of points Dylan scores per game which has been represented by g will be the total points scored divided by the number of game played. This will be:
g = total point scored ÷ number of games played
g = 48 ÷ 4
Therefore, option A is the right answer.
