Answer:
A manufacturing machine has a 40% defect rate. If 131 items are chosen at random, then:
- The random variable, X=Number of 131 randomly selected items that are defective.
- Number of Items, n=131
- The point estimate of defective items, p=40%=0.4
Answer:
millicoulomb
Step-by-step explanation:
millicoulomb is 1*10^-3 Coulombs
From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :
