Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The number of light produced in an hour is n = 922
The proportion of the bulb that are defective is p = 0.0334
Generally given from the question that we should use binomial distribution it then means that the standard deviation is mathematically evaluated as
=> 
=>

108 - (24+4) = 80
Answer:
The resultant force magnitude is 129.90 pounds at angle of 60°
Step-by-step explanation:
Two given forces and resultant force form right triangle. The first force (150 pounds) is hypotenuse, the second force ( 75 pounds) and resultant force are right sides of the right triangle.
Then we can write pythagorin theorem
R= √150∧2 - 75∧2 = √ 22500-5625 = √16875 = 129.90
Good luck!!!
