The value of C=1/3 for the probability density function f(x)=cx , 0<x<2.
<h3>What is probability density function?</h3>
The probability density function is a function of a continuous random variable, whose integral across an interval gives the probability that the value of the variable lies within the same interval.
Given that:
Here we can see that the value of x is varies as 0,1,2
So at 0,1,2 the value of the function is
So the probability density function is given as:
Hence the value of C=1/3 for the probability density function f(x)=cx , 0<x<2.

Answer: y=-5 x=5
explanation: look at the number the x and y is on
-3x + 2y = -3
4x - y = -1
2(4x - y = -1)
-3x +2y = -3
8x -2y = -2
-5x = -5
/-5
X = 1
Answer:
a) 24 [cm]; b) 30°.
Step-by-step explanation:
a) the length of full the circle is: min_arc(AB)+maj_arc(AB)=π(22+2)=24π [cm]. Then the radius is: r=L/π; ⇒ r=24π/π=24 [cm];
b) if the full circle is 360° (L=24π), then m(∠AOB):2=360°:24 and the required measure of the acute angle AOB is:
m(∠AOB)=360*(1/12)=30°.
