Problem 2. A random variable has the following density function:
f (x) = 1- 0.5x 0 < x < 2

a. Graph the density function.
b. Verify that f(x) is a density function.

Answers

If f(x) is a density function, then its integral over the entire real line should be 1:

[tex]\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2(1-0.5x)\,\mathrm dx=(x-0.25x^2)\bigg|_0^2=2-1=1[/tex]

so yes, f(x) is indeed a density function.

The answer is C because A and X are in the same place.

C because the angles match up together. Triangle ABC congruent to triangle XYZ. angle A = angle X, angle B is congruent to Y, angle C is congruent to Z. They match up. The vertex’s (B &Y are congruent) because they are both vertex’s. I hope this makes sense.

The perimeter of a triangle is 69Cm. Side a is 5cm shorter then side b. side c is 5 more than twice side b. Find the length of each side

Answers

Step-by-step explanation:

Given parameters:

Perimeter of triangle = 69cm;

Unknown:

Length of each side = ?

Solution:

Side a is 5cm shorter than side b;

b = a + 5 ----- i

Side c is 5 more than twice side b;

c = 2b + 5

The three sides of triangle are a, b and c;

Perimeter is the sum of sides of a body;

a + b + c = 69

From i;

a = b - 5

c = 2b + 5

so;

b - 5 + b + 2b + 5 = 69

4b = 69

b = 17.25cm

a = b -5 = 17.25 - 5 = 12.25cm

c = 2(17.25) + 5 = 39.5cm
