Lets get started!
In this case, it's quite simple.
<em>Multiply</em> both <em>numerators by each other </em>
The number are the top numbers of the fraction
-5 x 2 = -10
Now we <em>multiply the denominators,</em> the bottom numbers
8 x 3 = 24
Your final answer is -10/24
If you want to simplify (meaning to make smaller or easier to look at), <em>divide </em>the top and bottom numbers by 2
Your simplified answer is -5/12
Hope I helped :)
Answer:
6 buses are used and the last bus has 48 people on it
8 would be the constant but in this situation there is a variable next to it so I’m not sure if it would be considered a constant
Answer:
8a(5a - 4)
Step-by-step explanation:
To factor this expression, see what numbers and variables these two terms have in common. I can see that they both have the variable a, so a can be factored out.
40 and -32 also have 8 in common, because they are both cleanly divisible by 8.
Now we can factor 8a out of 40a^2 - 32a. Think of how many times 8a goes into 40a^2 and -32a.
8a(5a - 4)
Mutually exclusive means that the intersection of the events is empty: P(S and T) = 0.
P(S or T) = P(S) + P(T) = 29% + 49% = 78%
If events S, T are not mutually exclusive, then P(S or T) = P(S) + P(T) - P(S and T)
