Answer:
Two Angles are Supplementary when they add up to 180 degrees.
Step-by-step explanation:
Well...it depends on how fast you're riding your board. I used to longboard to school which is about 3 hours away and it only takes me about 10-15 minutes and that depends if I'm going faster or slower than usual or if the street lights are extra long etc. I probably go faster when I have new bearings, too.
<h3>
Answer: 25 times</h3>
Explanation:
There are 428 pages, starting with 1. So we have the set 1,2,3,...,427,428.
The set of even numbers is 2,4,6,...,426,428 which represents half of the previous set mentioned. It might help to look at a smaller set like {1,2,3,4} and note that the evens make up half of this and the odds make up the other half.
So the probability of landing on an even page is 1/2 = 0.5; multiply that with the number of experiments done to get (1/2)*50 = 25 which is the number of times we expect to land on an even-numbered page.
Answer:
Yes, Holmes is correct.
Step-by-step explanation:
Let's separate each statement of Holmes: (they are all true)
- If Mrs. Smith is lying then Moriarty has not escaped.
- Either Moriarty is dead or he is really Jones.
- If Moriarty is really Jones then he has escaped.
- I am convinced Mrs. Smith is lying.
If we start with the last one, we know that Mrs. Smith is lying. That takes us to the first one, Mrs. Smith IS lying, so Moriarty has not escaped.
If we look the second one, either Moriarty is dead or he is really Jones.
If he is really Jones, that takes us to the third statement that says that Moriarty has escaped. But we know from the first statement that he hasn't escaped, so he can't be Jones.
So, going back to the second statement, Moriarty is dead.
