Given:
50% of the people that get mail-order catalogs order something.
Determine the probability that exactly 2 out of 10 people getting the catalogs will order something.
If the total number of people is 10, we can calculate the number of people who will order something from the catalogs:
10 * 0.50 = 5 people.
The probability that exactly two out of ten people will order something is:
2/5 = 0.4
Therefore, there is a 40% chance that the exact two people who received the catalogs will order something from it.
One solution BECAUSE they only intersect once!
Many solutions means they are on top of each other
No solutions means they are parallel to each other!
We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:
However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable 
, where stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our by -2.5. We can now add this term into our equation:
We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:
It will take us 6 hours, or choice A.
Answer is B because if you divide 81 by 9 it will equal to 9.
