How do I do this equation

The ideal gas law gives the relationship between the pressure, volume and temperature of a gas sample. Mathematically, it is given by :

PV = nRT.... ( 1 )

Where n is the amount of gas, R is a physical constant

Value of P from equation (1),

Value of V from equation (1),

Value of n from equation (1),

Value of R from equation (1),

Value of T from equation (1),

So, the correct options are :

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
