Answer:
0.0244 (2.44%)
Step-by-step explanation:
defining the event T= the chips passes the tests , then
P(T)= probability that the chip is not defective * probability that it passes the test given that is not defective + probability that the chip is defective * probability that it passes the test given that is defective = 0.80 * 1 + 0.20 * 0.10 = 0.82
for conditional probability we can use the theorem of Bayes. If we define the event D=the chip was defective , then
P(D/T)=P(D∩T)/P(T) = 0.20 * 0.10/0.82= 0.0244 (2.44%)
where
P(D∩T)=probability that the chip is defective and passes the test
P(D/T)=probability that the chip is defective given that it passes the test
Convert 79% to a decimal which is .79
Then you multiply .79 by 32 which is 25.28
Your answer is 25.28
Answer:
i dlnt know 15 I think not sure
Answer:
6
Step-by-step explanation:
put unknown as y
area of rectangle = width × long
y(y - 2)=48
y² -2y =48
u can use scientific calculator to find this
y²-2y-48=0
(y-8)(y+6)=0
y=8 y=-6
take the positive value and ignore the negative value
width=y-2 long=8
8-2=6
I hope this help you :)
