Answer:
A batch of 20 semiconductor chips is inspected by choosing a sample of 3 chips. Assume 10 of the chips do not conform to customer requirements.
a) Number of different samples = 20C3 = =1140
b) 2 good and one bad chip
Number of samples = 10C2 * 10C1 = 45 * 10 =450
c) 2 good 1 bad + 1 good 2 bad + 3 bad
Number of samples = 10C2 * 10C1 + 10C1 * 10C2 + 10C3
=
Answer is parallel lines
Reason - same slope (3x) and different y intercept means they will be parallel lines because their slope is the same but they will cross the y axis at different points.
I changed the first equation to y intercept form
y = 3x - 10 to match the other equation
y = 3x - 6

C. 2.3
D.√144
Rational roots or decimals are numbers that have an end point.
pi 'technically' never ends, while √50 = 7.07106781<span>…, which never ends either
