we know that
Angles in a linear pair are supplementary angles
So
Let
A-------> the first angle
B------> the second angle
----> equation
Substitute the values of A and B in the equation
therefore
the answer is
the value of x is

Answer:
Step-by-step explanation:
Given is the probability distribution of a random variable X
X 4 5 6 7 Total
P 0.2 0.4 0.3 0.1 1
x*p 0.8 2 1.8 0.7 5.3
x^2*p 3.2 10 10.8 4.9 28.9
a) E(X) = Mean of X = sum of xp = 5.3
Std dev = square root of variance = 0.9
------------------------------------
b) For sample mean we have
Mean = 5.3
Variance = var(x)/n =
c)
