Answer:
Step-by-step explanation:
Given that the weights of bags filled by a machine are normally distributed with a standard deviation of 0.055 kilograms and a mean that can be set by the operator.
Let the mean be M.
Only 1% of the bags weigh less than 10.5 kilograms
i.e. P(X<10.5) = 0.01
corresponding Z value for P(Z<z) = 0.01 is -0.025
i.e. 10.5 = M-0.025(0.055)
Solve for M from the above equation
M = 
Rounding off we get
10.50 kgs
Mean weight should be fixed as 10.50 kg.
Go to NASA's website. I'm not sure you can because we don't know the scale of the picture but if you are given one such as 1 cm = 500 miles or something like that, you just find the center of the circle and make a line through it. If the line measures 4.5 cm then the diameter is 2500 miles. This is an example. YOU'RE WELCOME :D
25% of 28,000 is 7,000.
If the unit depreciated by 7,000, it is now worth 21,000.
