Is there a picture or a graph? Not enough info I’m sorry!

It was started by a scientist Ivan Pavlov who was a russian physiologist who started the Behaviorist movement in psychology.
During the experiment:
- The loud noise is the <u>unconditioned stimulus.</u>
- The fear reaction is the <u>unconditioned response.</u>
- The white rat is our <u>neutral stimulus.</u>
- When the loud noise and the white rat are paired over time, the white rat becomes the <u>conditioned stimulus.</u>
- The Fear reaction to the loud noise the <u>conditioned response.</u>
Our Answer is:
⛱️ 
For the first flower she has a choice of 15. For the second 14 (15 minus the one that was already used). For the third 13, and so on.
Each of the first 15 can be match with any of the second 14. Any of the first pairs can be matched with ant of the third 13 and so on.
This gives us
Number of Selections = Choices for Flower 1 x Choices for Flower 2 x Choices for Flower 3 x Choices for Flower 4 x Choices for Flower 5



You could also calculate this as the permutation 
Y = x + 8....the slope here is 1. A parallel line will have the same slope.
y = mx + b
slope(m) = 1
(2,16)....x = 2 and y = 16
now we sub into the formula and find b, the y int
16 = 1(2) + b
16 = 2 + b
16 - 2 = b
14 = b
so ur equation is : y = x + 14 <==
Answer:
412.
Step-by-step explanation:
412 =
1) less than 500
2) two even digits
3) quadrilaterals have 4 sides
4) 4 + 1 = 5 and there are 5 nickels in a quarter
5) the digital root of 412 is 7
