Answer:
0.637
Step-by-step explanation:
The average value of a whole sinusoidal waveform over one complete cycle is zero as the two halves cancel each other out
There are about 20 yellow marbles.
The experimental probability is 5/20, since 5 yellow marbles were drawn out of 20 in the sample.
5/20(80) = 400/20 = 20
Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets
(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2
The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is

Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle
Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.
The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
