Because there are so many different chances to get something else.
On the right side of the graphs it shows how many years on the bottom. It ends on te top right which seems to be 50 years.
First consider (x+c)^2 where c is just a random constant. if we expand this by foil (which is distributive property twice), we get x^2 + 2cx+ c^2. we want to find c^2 and to do that, we can first find c. we can find c by looking at the 2cx term. this term should match with 12x, so therefore 2c = 12 so c = 6. this also implies that c^2 = 36.
note that for this problem i was working backwards which is a very powerful problem solving tool: start with what you want to attain, and then see how you can go from where you are now to get to your destination.
let me know if you have any questions!!!
Total juice boxes = 3 + 1 + 2 + 4 = 10
probability first one out is grape = 2 / 10
probablility second one out is grape 1 / 9 (one taken already and only nine left)
total probability = 2 / 10 x 1 / 9 = 2 / 90 = 1 / 45
Answer:
The measure of the angle Y in given triangle is 120 º.
Step-by-step explanation:
Here, in ΔXYZ
∠X = 34 º , ∠Z = 26 º
By, ANGLE SUM PROPERTY of a Triangle:
Sum of all the interior angles in any given triangle is always 180 º.
⇒ ∠X+ ∠Y + ∠Z = 180 º
or, 34 º + ∠Y + 26 º = 180 º
or, ∠Y = 180 º - 60 º
⇒ ∠Y = 120 º
Hence, the measure of the angle Y in given triangle is 120 º.
