Answer:
The frequency by which the equipment should receive periodic maintenance is
Step-by-step explanation:
A Wellbull distribution is mathematically represented as
Where x is the frequency that the equipment should receive periodic maintenance
probability of a breakdown before the next scheduled maintenance is mathematically represented as
Substituting 2 for and 60 for 0.05 for P(x)
Let
=>
=>
Multiply both sides by minus
=>
Substituting this into the equation
Integrating and substituting back for x
substituting for the range of x and 0
Taking ln of both sides
making x the subject of the formula

Answer:
(6x5 -6) +56
(30-6) +56
24+56
80
Step-by-step explanation:
K= 3 is the starting value for k. The number six means the sum of 3 to 6.
Replace k with the values and solve:
K = 3 = -2(3) + 5 = -1
K = 4 = -2(4) + 5 = -3
K = 5 = -2(5) + 5 = -5
K = 6 = -2(6) + 5 = -7
Sum = -1 + -3 + -5 + -7 = -16
Sum = -16
The area of the box is 12 x 19 which is 228.
then the area of the circle is 3.14 x 36 which is 113.04.
228 + 113.04 = <span>341.04
hopefully i could help ;)</span>
