1. To evaluate the defect rate of its memory chips, an integrated circuit manufacturer
tests every 100th chip off the production line. Out of 10 chips tested, one chip is found
to be defective. The manufacturer concludes that 3 chips out of 3,000 will be defective.

answer: it is a.,b.,d.

step-by-step explanation:

b. b < 1 might be the correct answer

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
