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
Answer:
$20.70 increase per week!
Step-by-step explanation:
multiply 690 * 0.03 (aka 3%) to get 20.7 which equals $20.70
if you want to know how much she made the next week altogether, add 690 + 20.70 to get $710.70!
Answer:
The Cost Price will be $19.99
Step-by-step explanation:
James
Sale Price = (100 - Discount Rate) x Cost Price
Let Y = Cost Price
By Putting the values in above equation:
$16.99 = (100 - 15) x Y
$16.99 = 0.85Y
Dividing the equation by 0.85, we get
Y = $16.99 / 0.85
Y = $19.99
