Let X have the probability mass function P(X = −1) = 1 2 , P(X = 0) = 1 3 , P(X = 1) = 1 6 Calculate E(|X|) using the approaches

Studentka2010 [4]

Answer:

Step-by-step explanation:

From the given information:

Note that the possible values of Y are 0 and 1 because;

y = 0 if X = 0 and y = 1 if X = ±1

∴

$P(Y =0) = P(X = 0) =\dfrac{1}{3}$

$P(Y = 1) = P(X = -1 \ or \ 1) \\ \\ = P(X = -1) + P(X = 1)$

$= \dfrac{1}{2}+ \dfrac{1}{6}$

$=\dfrac{3+1}{6}$

$= \dfrac{2}{3}$

$E(|X|) = \sum |x| P(X=x) = ( 1 \times \dfrac{1}{2}) + ( 0\times \dfrac{1}{3}) + ( 1 \times \dfrac{1}{6})$

$= \dfrac{2}{3}$

To get 20% of something, you must divide it by 5 since 20*5=100
Anyway, since Jada's dog is 20% of it's adult weight, but currently weighing 9kg, we must multiply that by 5
9*5=45kg
Jada's dog's adult weight is 45kg
Hope it helped

Determine whether the following system of equations has one solution, no solution, or an infinite number of solutions. Explain y

expeople1 [14]

A) 2x - 4y = 10
B) 7x - 9y = 12
Multiplying equation A by -3.5
A) -7x +14y = -35 then adding B
B) 7x - 9y = 12
5y = -23
y = -4.6

2x -4*-4.6 = 10
2x + 18.4 = 10
2x = -8.4
x = -4.2
It has one solution (-4.2, -4.6)
