Answer:
Probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.
Step-by-step explanation:
We are given that the diameters of ball bearings are distributed normally. The mean diameter is 106 millimeters and the standard deviation is 4 millimeters.
<em>Firstly, Let X = diameters of ball bearings</em>
The z score probability distribution for is given by;
           Z =  ~ N(0,1)
 ~ N(0,1)
where,  = mean diameter = 106 millimeters
 = mean diameter = 106 millimeters
              = standard deviation = 4 millimeter
 = standard deviation = 4 millimeter
Probability that the diameter of a selected bearing is greater than 111 millimeters is given by = P(X > 111 millimeters)
     P(X > 111) = P(  >
 >  ) = P(Z > 1.25) = 1 - P(Z
 ) = P(Z > 1.25) = 1 - P(Z  1.25)
 1.25)
                                                   = 1 - 0.89435 = 0.1056
Therefore, probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.

Answer:
c = 1, f = 5, and r = 1
Step-by-step explanation:
5(1)/(5) = 1/(1)
5/5 = 1/1
1 = 1
 
        
                    
             
        
        
        
Answer: see last picture
Step-by-step explanation:
We see that the y-intercept is 10 and the slope is -3
so when x = 0, y = 10
Graph this first point (picture 1)
Since the slope is -3, every time you go one unit to the left, you go down 3 units, so graph this second point (picture 2)
Continue this until you have no more room on the graph (picture 3)
now draw a line through the dots (picture 4)
 
        
             
        
        
        
Answer:
x=1 y=-5
Step-by-step explanation:
7(5x-2y=15) --->      35x-14y=105
2(7x+7y=-28) -->  + <u>14x+14y=-56</u>
                                49x=49  --->x=1
5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
