Answer:
Thickness of gold foil will be
Step-by-step explanation:
We have given that a sheet of gold foll is 0.28 millionth of a meter thick
We know that 1 million = 1000000

Answer:
is the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory
Step-by-step explanation:
The two events are independent of each other.
Hence the probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 is equal probability of choosing satisfactory piston from Machine 1 + probability of choosing unsatisfactory piston from Machine 2
Substituting the given values we get
Probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 =

A right parenthesis ) is missing from this problem statement. I'm assuming that you meant
<span>3 1/2+( 2+4 1/2).
There are at least two ways in which you could do this problem. One would be to simply drop the parentheses entirely:
</span><span>3 1/2+ 2+4 1/2 It'd make sense to add 3 1/2 and 4 1/2 together FIRST, and then to add 2 to the result.
Or, do the work inside the parentheses FIRST: </span><span>3 1/2+( 2+4 1/2).
</span>
This simplifies the problem to <span>3 1/2+( 6 1/2).
You MUST get the same answer either way.</span>
