Circuit boards for wireless telephones are etched, in an acid bath, in batches of 100 boards. a sample of seven boards is randomly selected from each lot for inspection. a particular batch contains two defective boards; and x is the number of defective boards in the sample. p(x

0.8642

Step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
