Answer:
Bottom-up processing
Explanation:
The information collected from the environment are used to determine how we interact with our environment. The process and manner that the information derived from our sensory organs are put together, analyzed and understood, and the experience felt consciously is knowns as perception
The order of the process of perception can be such that the perception is comes from and is based on the direct stimuli on our senses which is known as bottom-up processing. Whereby the the observed sensation are rather analyzed and interpreted based on previous knowledge or thought process, the order is referred to as top-down processing.
number of different pairs the teacher can choose= nCr (18+14, 2)=496
no. of opposite gender pairs possible= 14 (since there are only 14 boys)
probability = 14/496= 7/248
A. True because it's a map where you need to go and where things are so its your own mental map.
Answer:
2.57
Explanation:
Given the data:
X : 17, 17, 16, 17, 23, 22, 21
Mean absolute deviation (MAD) :
Σ|x - xbar| ÷ n
xbar = Σx/ n
n = 7
Σx = (17 + 17 + 16 + 17 + 23 + 22 + 21) = 8
xbar = 133/7 = 19
|x - xbar| :
|17 - 19|= 2
|17 - 19| = 2
|16 - 19| = 3
|17 - 19| = 2
|23 - 19| = 4
|22 - 19| = 3
|21 - 19| = 2
Therefore,
MAD = (2+2+3+2+4+3+2) / 7
MAD = 18 / 7
MAD = 2.57
