What is dilation and how do you determine the scale factor?

Dilation is the type of change that changes the size of the image and has a scale factor. Which measures how large or small a picture is and is also called a scalar factor. You can determine the scale factor by starting with ΔABC, and then draw the dilation picture of the triangle with the middle at the origin and a scale factor of two. On the other hand, notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation also has a scale factor 2, multiply by 2.

Step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
