<span>The ratio of the corresponding side lengths of similar triangles is called the <u>scale </u>factor.
This means that </span><span> all the sides of the small figure are multiplied by the same number to obtain the lengths of the corresponding sides of the large figure.</span>
The slope of line D is also -4 because the lines are perpendicular.
If 1 inch equals 20miles then 8 inches equals 20 x 8 = 160 miles.
<span>Lets say the 1st die rolled a 2 -
there would be 2 combinations for which the sum of dice being < 5 :
2,1
2,2
Now say the 2nd die rolled a 2 -
there would be 2 combinations for which the sum of dice being < 5 :
1,2
2,2
Now we want to count all cases where either dice showed a 2 and sum of the dice was < 5. However note above that the roll (2,2) is counted twice.
So there are three unique dice roll combinations which answer the criteria of at least one die showing 2, and sum of dice < 5:
1,2
2,1
2,2
The total number of unique outcomes for two dice is 6*6=36 .
So, the probability you are looking for is 3/36 = 1/12</span>
