Answer:
Factors are (x-9)(x+4)
Step-by-step explanation:
Hey there,
The answer is: 18a^3b2/2ab=9a^2*b
:)
Answer:
a = 0,-1
Step-by-step explanation:
a^2 + a=0
Factor out an a
a(a+1) =0
Using the zero product property
a=0 a+1 =0
a=0 a= -1
Answer:
3/4
Step-by-step explanation:
.74(75%) is equal to 75/100
The greatest common factor is 25, so divide 75 by 25 and 100 by 25.
75/25=3 100/25=4
So, 75/100 simplified is 3/4.
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.
