Answer:
Step 2 is where this person went wrong
Step-by-step explanation:
Should be
11 + (9)(3)= x
11 + 27= x
x = 38
So for this you need to set the two equations equal to each other. 20+.05x=10+.07x then solve. Subtract .05 from both sides and get 20=10+.02x. Then subtract 10 from the other side and get 10=.02x Isolate x by dividing 10 by .02. This leaves you with the answer of 500 texts.

Answer:
The answer to your question is time = 15 s
Step-by-step explanation:
Data
Distance traveled = 1/20
time = 3/4s
total time = ?
Process
If we know that the object travels 1/20 of the total in 3/4 means that all the path has 20 sections. So, to find the answer, we must multiply 20 by the time it takes to travel that distance.
Total time = (20)(3/4)
= (20 x 3)/4
= 60/4
= 15 s
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.
