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)
where, = mean diameter = 106 millimeters
= 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 1.25)
= 1 - 0.89435 = 0.1056
Therefore, probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.

6.25 per circle to balance the hanger
<h2>3</h2>
Step-by-step explanation:
The equation of line passing through the two points is
When substituted,the equation becomes
which when simplified is
The line clearly passes through origin.
The distance between two points is
Distance between origin and is .
Distance between origin and is
Scale factor is
So,scale factor is
which when simplified becomes 3.
