Answer:
3.54% probability of observing at most two defective homes out of a random sample of 20
Step-by-step explanation:
For each house that this developer constructs, there are only two possible outcomes. Either there are some major defect that will require substantial repairs, or there is not. The probability of a house having some major defect that will require substantial repairs is independent of other houses. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
30% of the houses this developer constructs have some major defect that will require substantial repairs.
This means that 
If the allegation is correct, what is the probability of observing at most two defective homes out of a random sample of 20
This is
when n = 20. So






3.54% probability of observing at most two defective homes out of a random sample of 20
Answer:
"Make sure one of them is a match"
Step-by-step explanation:
It takes a little practice and above all to generate heat through friction. By raising the temperature of the woods, it is possible to reach the ignition temperature through friction.
Fires require good equipment and good technique. The majority of times it fails is due to a lack of technique and equipment. This can make learning difficult.
For wood selections, you generally want to comply with the following:
- Dry Tinder
- You should be able to press the wood. If you can't, then it is too difficult.
- Wood not very strong but not soft
- Not sap in the wood
Make the friction forming a 90 degree angle between them, like a cross. Keep one of the sticks supported on the floor vertically, and the other horizontally rubbing it against it at rapid speed, at intervals.
Under this wood put dry tinder that is able to ignite quickly once you generate the fire.
And for the Puzzle remember the orden of the words:
<h2>Make sure one of them is a match. </h2>
Use tree wood, rub and heat until ignition is generated.
Ok so this might be a bit confusing but I hope u understand it. Because the problem is in seconds, I tried to stick to seconds. In an hour there are 60 minutes and in those 60 minutes there are 3,600 seconds. Now in 25 seconds the mule deer can run 1/4 mile. So think for a second how many seconds it would take for it run a full mile. If u do the math then u would get 25*4 which is 100 seconds to run a full mile. Going back to our 3,600 seconds, all u have to do is divide it by 100 to get the miles. So 3,600/100 is 36. The mile deer runs 36 miles in an hour. I hope this was of help to u
