Answer:
-4 1/4
Step-by-step explanation:
-7 3/4 + 3 1/2 = -4 1/4
Answer:
Raoul estimated the difference to be: 89
97.23 --> 97
8.3 --> 8
97-8= 89
The actual difference is: 88.93
97.23-8.3 = 88.93
If
has to be a solution of the equation, just plug it in:
![(\pm 15i)^2 + [1] = 0 \iff -225 + [1] = 0 \iff [1] = 225](https://tex.z-dn.net/?f=%20%28%5Cpm%2015i%29%5E2%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20-225%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20%5B1%5D%20%3D%20225%20)
So, the solutions of
are
Using probability concepts, it is found that:
1. P(A) = 0.2268.
2. 100%.
3. 0%.
-------------------------
A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>
Item 1:
- 44 countries in Asia.
- Total of 23 + 12 + 47 + 44 + 54 + 14 = 194 countries.
Then:

Itens 2 and 3:
- The complement of an event is it's negation.
- Either an event happens, or it does not, that is, either the event happens, or it's complement does, thus the sum of the probabilities of an event and it's complement is of 100%.
- From the above bullet point, there is also a 0% probability that neither an event nor its complement happens.
