Answer:
There are 36 possibilities per character (26 lower case letters + 10 numbers), so the total number of permutations are 36^4 = 1,679,616
Step-by-step explanation:
Integers and Rational Numbers, it is because if -11 is a Integer, it also has to be a Rational number. But your actual answer is Integers.
Best thing you can do in order to answer all of this is to use the <span>Bernoulli trials. You can look for it and see if the answers I'm giving you are correct:
</span><span>Probability of occurring 4 times = (1/10)^4
Probability of never occurring = (9/10)^4
Probability that it occurs at least once = 1 - (9/10)^4
Probability that it occurs in the fourth trial only = (9/10)^3 * 1/10
</span>I think this is going to be very helpful
The third angle is 56 degrees because it is a right <u>triangle</u>, so the three angles will add up to 180 degrees. Since it is a right triangle, you know one angle is 90 degrees. All you have to do is add 90 and 34, and then subtract that from 180 to get your third angle.
