Given:
6 male professores
9 female professores
5 male teaching assistants
6 female teaching assistants
Sol:.
N (professors)
N(Male)
N(professors and male)
N(professors OR male) = N(professors) + N(males) -N(professor OR male)
N(People to choose from)
Then probablitiy is:
Then the probability is 10/13
Answer:
1. Technically 2, but might be 0 in your teacher's opinion.
2. 1
Step-by-step explanation:
Solving problem one.
So I don't know if you have learned about imaginary numbers, but if you have, then you would end up with two answers if you plugged in the quadratic formula.
If you haven't learned about imaginary numbers, then I would say your best option would be to write 'No real solution' since there are technically 2 solutions.
Solving problem two.
Turns out this quadratic has a special property and it's actually a square of one equation. You can find out by just factoring the equation.
It's (3x-2)^2. Since it's squared, that means that only 2/3 would work as x in this equation.
First, note that
is always positive (except for x=0), so
must be always negative.
Thus, the only plausible graphs are 1 and 3 since they are below the x-axis.
Now,
and
are only defined for x≥0, because only for these x'es we can take the square root.
Note that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.
Answer: first graph
Answer:
200*34=6800
Step-by-step explanation:
Write the possible combinations like
200*34
200*43
300*24
300*42
400*32
400*23
then you chose what will give you 6800 as the answer
