Answer:
0.37072
Step-by-step explanation:
Let A be the event that step 1 is defective (P(A) = 10%), B the event that step 2 is defective(P(B) = 20%), C the event that step 3 is defective (P(C) = 8%), D the event that step 4 is defective(P(D) = 5%). Let us suppose that the occurance of a failure at any step is indepent of the other steps.
Recall the following properties


And given A, B, C, D independent , then

REcall that if the a set of events A,B,C,D are independent, their complements are also indepent.
Since we are asked for the probability of a defective item, this means that at least one of the steps is defective. Then, we are asked for the following probability:


Answer:
9.75 feet
Step-by-step explanation:
Note the question is asking "altogether". This is a key word to determine that you are adding the numbers given:
9 + 0.75 = 9.75 feet.
9.75 feet is your answer.

Substituting into the second expression,
I'm pretty sure this is the answer:
(10)sin(40°) = AC
It's <em>sin </em>becasue it <em>needs </em>the opposite side of 40° and <em>has </em>the hypotenuse.
Answer:
the answer is 24
Step-by-step explanation:
times 4 by 7 to get 24 because we only need the botom of the prism so if their 1 inch by 1 inch then how many times can it fit in seven only seven times so times that by how long it is witch is four then you would get 24
