Answer:
$114.3
Step-by-step explanation:
Number of hours worked last week  = 12hrs 
Amount earned for her work hours = $98
  The rate at which she earned =  ?
         Rate =  
  
         Rate  =  = $8.17/hr
    = $8.17/hr 
Now; 
 Since the total hours she worked during the weekend  = 14hrs
   Amount earned  = $8.17/hr   x 14hrs   = $114.3

Answer:
 the probability is 0.0750
Step-by-step explanation:
The computation of the probability is shown below;
The mean of x is 
= 1.5 ÷ √79
= 0.1688
Now the probability is 
= P(Z < -0.3 ÷ 0.1688) + P(\bar{x} > 0.3 ÷ 0.1688)
= P(Z < -1.78) + P(Z > 1.78)
= P(Z < -1.78) + 1 - P(Z < 1.78
= 0.0375 + 1 - 0.9625
= 0.0750
hence, the probability is 0.0750
 
        
             
        
        
        
Answer:
x = -3, y =3
Step-by-step explanation:
y = -4/3x - 1
y = 1/3x + 4 -------> 4y = 4/3x + 16
Adding the first equation and the new second equation together:
5y = 15 ------> y = 3
Plug y = 3 into one of the original equations:
3 = 1/3x + 4
-1 = 1/3x 
x = -3
