Revenue, R = 130x
Profit, P = Revenue – Cost
P = R – C
P = 130x – 2950 + 6x + 0.1x^2
At P = 0
0 = -2950 + 136x +0.1x^2
X = 21.355, -1381.355
Therefore, manufacture greater than 21.355 items to make
profit.
Answer:
Step-by-step explanation:
Given that the bivariate distribution of X and Y is described below:
x 1 2
y
1 0.21 0.14 0.35
0 0.47 0.18 0.65
Pdf of Y is
Y 1 0
p 0.68 0.32
C) Pdf of X is
x 1 2
p 0.35 0.65
Mean of X = 
Var(x) = E(x^2)-Mean ^2 = 
C) Mean of Y = 1(0.68)+0 = 0.68
Var(y) = 1(0.68)-0.68^2
= 0.2176

Answer:
20 degrees
Step-by-step explanation:
I don't know why the 30 degrees was given at point A because you don't need that.
The equation is;
Sinx= Opposite/Hypotneuse
x = Sin inverse (50/146)
= 20.02
Rounded to 20 degrees
