6x - 12y = 24 ⇒ 6x - 12y = 24
-x - 6y = 4 ⇒ -2x - 12y = 8
8x = 16
8 8
x = 2
-x - 6y = 4
-(2) - 6y = 4
-2 - 6y = 4
+ 2 + 2
-6y = 6
-6 -6
y = -1
(x, y) = (2, -1)
Angle 1 = 96
angle 2 = 36
angle 3 = 48
Answer:
Option A 0.312 is right
Step-by-step explanation:
Given that iN Maplewood a certain type of DVD player is sold at just two stores, 43% of the sales 13) are from store A and 57% of the sales are from store B. 2.4% of the DVD players sold at store A are defective while 4.0% of the DVD players sold at store B are defective.
Prob for any random item form store to be defective = Prob from A and defective +Prob from B and defective

Prob it came from A and defective = 0.
If Kate receives one of these DVD players as a gift and finds that it is defective, what is the probability that it came from store A
=
