Continuous Random Variables

Problem

Let X be a random variable with PDF given by

fX(x)={cx20|x|≤1otherwise

Find the constant c.

Find EX and Var(X).

Find P(X≥12).

Solution

Problem

Let X be a continuous random variable with PDF given by

fX(x)=12e−|x|,for all x∈R.

If Y=X2, find the CDF of Y.

Solution

First, we note that RY=[0,∞). For y∈[0,∞), we have

FY(y) =P(Y≤y)

=P(X2≤y)

=P(−y√≤X≤y√)

=∫y√−y√12e−|x|dx

=∫y√0e−xdx

=1−e−y√.

Thus,

FY(y)={1−e−y√0y≥0otherwise

Problem

Let X be a continuous random variable with PDF

fX(x)={4x300<x≤1otherwise

Find P(X≤23|X>13).

Solution

Problem

Let X be a continuous random variable with PDF

fX(x)={x2(2x+32)00<x≤1otherwise

If Y=2X+3, find Var(Y).

Solution

Problem

Let X be a positive continuous random variable. Prove that EX=∫∞0P(X≥x)dx.

Solution

Problem

Let X∼Uniform(−π2,π) and Y=sin(X). Find fY(y).

Salsk061 [2.6K]

Answer:

1 meter =1,000 millimeters. So, the scale is:


7 mm:1,000 mm                      Divide both sides by 7


1 mm:142 6/7 mm - This is the scale that Tess used.

Oliver has 2 pieces of rope that are each 3 1/2 ft long. He also has a piece of string that is 2 1/4 ft long. Olivier needs to c
ser-zykov [4K]
This is the concept of arithmetic; given that a string was cut into 3 equal pieces.
The length of each piece will be:
[length of the string]*3
length of the string=2 1/4 ft=9/4 ft
thus the length will be:
9/4÷3
=9/4×1/3
=3/4 ft
thus we conclude that the length of each string will be 3/4 ft long

Trapezoid ZOID is congruent to trapezoid TRAP. If vertices 2 and have coordinates (0, -2) and (0, -5) respectively, which of the
vlada-n [284]

The trapezoids are congruent if the corresponding sides of each trapezoid are equal

The option that gives the possible coordinates for the vertex <em>I</em> is the option;

\underline{(-4.5, -5)}

Reason:

The given coordinates of the trapezoid TRAP = T(3, 5), P(3 2), R(6, 5), and A(7.5, 2)

The given coordinates of the trapezoid ZOID = Z(0, -2), and D(0, -5)

Required: The possible coordinates for a vertex on ZOID

Solution:

The given points of the trapezoid are the height of the trapezoid ZOID

The possible vertex of <em>I</em>, and <em>O</em> are;

  • I(4.5, -5), I(-4.5, -5), O(3, -2), O(-3, -2)

Therefore;

The option that gives the possible coordinates (position) of a vertex <em>I</em> is the option \underline{(-4.5, -5)}
