Answer:
A) Between 1750 and 1760 many improvements were made. Improvements such as spinning and waving the coal on machines were examples of this.
B) Improvements such as said above helped dramatically. They helped by using their power to smelt iron and steel. Because of this, economic life improved.
C) Mining coal helped transform social and economic life. It transformed life because it pumps out deepening mines. Because of this, more and more power transfers to keep the machines running.

Answer:
A. Rural to urban migration increases the population density to eastern China
Perceptual is a mental predisposition that functions as a lens through which we perceive the world and our learned concepts (schemas) prime is to organize and interpret ambiguous stimuli in certain ways.
example of perception: knowing when to try a different technique with a student to increase their learning
example of schemas: in Piaget’s theory of development, children construct a series of schemata, based on the interactions they experience, to help them understand the world
Piaget’s (1936) Theory: cognitive development explains how a child constructs a mental model of the world. He disagreed with the idea that intelligence was a fixed trait, and regarded cognitive development as a process which occurs due to biological maturation and interaction with the environment. He was also a Psychologist. (this is just something in case your teacher asks about piaget’s theory/what it was about)
Hope this helps!
They should both be valued equally.
Answer:
Explanation:
Given the data:
X ___ : 0____ 1 ___ 2 ____ 3 ____ 4
P(X)__: 0.35_0.3___, b ___0.05_ 0.05
Σp(x) = 1
Hence,
0.35 + 0.3 + b + 0.05 + 0.05 = 1
0.75 + b = 1
b = 1 - 0.75
b = 0.25
The mean :
E(x) = Σ(X * p(x))
E(x) = (0*0.35)+(1*0.3)+(2*0.25)+(3*0.05)+(4*0.05)
E(x) = 0 + 0.3 + 0.5 + 0.15 + 0.2 = 1.15
Standard deviation = sqrt(Var(x))
Var(x) = Σx²p(x) - E(x)
Σx²p(x) = (0^2 * 0.35)+(1^2 * 0.3)+(2^2 * 0.25)+(3^2 * 0.05)+(4^2 * 0.05)
= 2.55 - 1.15
= 1.4
Sqrt(1.4) = 1.183
