Answer:
19.24 weeks
Step-by-step explanation:
Given that;
Mean, m = 18
Standard deviation, s = 3
Break down cost = 2000
Preventive maintenance cost = 1400
The optimal preventive maintenance level is Given by :
Mean + service level * standard deviation
Service level = preventive maintenance cost / (breakdown cost + preventive maintenance cost)
Hence,
Service level = 1400/(1400+2000) = 1400 / 3400
Service level = 0.4117647
Optimal preventive maintenance level :
18 + (0.4117647 * 3)
18 + 1.2352941
= 19.235
= 19.24 weeks

Answer:
The standard form of a parabola is
y=ax2+ +bx+c, where a≠0.
To find the vertex, you need to find the x- and y-coordinates.
Answer:
y = -5
Step-by-step explanation:
<em>-</em><em>7</em> = <em>y </em><em>-</em><em>2</em><em> </em>
<em>y </em><em>=</em><em> </em><em>-</em><em>7</em><em> </em><em>+</em><em>2</em>
<em>y </em><em>=</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>
