Domain is another word for the x value. so, this question just asking us to solve for y when x = 7
first, substitute in x
y = 3(7) -4
and then solve for y
y = 21 - 4
y = 17
so, the range is 17 when the domain is 7
I guess your are selecting them without replacement, if so:
a) P(picking one defective) = 3/12
P(picking a 2nd defective) = 2/11
P(picking a 3rd defective) = 1/10
P(1 and 2 and 3 defective) = 3/12 x 2/11 x 1/10 = 1/220 = 0.0045
b) None defective: P( Non Defective) = 9/12 (follow Same logic):
9/12 x 8/11 x 7/10 = 21/55 = 0.38
Second method using combination:
a) ³C₃ / ¹²C₃ = 1/220 0.0045
B) ⁹C3 / ¹²C³ = 21/55 = 0.38
A quart is 32 ounces. The usual "bleach" is a 1.25% bleach solution, so you can't easily make a 5% solution from it. If you had pure "bleach" (usually sodium hypochlorite), you would need 5% of 32 ounces, which is 1.6 ounces of it. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
