allsm [11]

Answer:

Step-by-step explanation:

Given that X and Y are independent random variables with the following distributions:

x -1 10 1 2 Total

p 0.3 0.1 0.5 0.1 1

xp -0.3 1 0.5 0.2 1.4

x^2p 0.3 10 0.5 0.4 11.2

Mean of X = 1.4

Var(x) = 11.2-1.4^2 =  9.24    

     

y 2 3 5  

p 0.6 0.3 0.1  1

yp 1.2 0.9 0.5 0 2.6

y^2p 2.4 2.7 2.5 0 7.6

Mean of Y = 2.6

Var(Y) = 11.2-1.4^2 =  0.84

3) W=3+2x

Mean of w =3+2*Mean of x = 7.2

Var (w) = 0+2^2 Var(x)= 36.96

If your income was ​$40 and the price of pizzas was ​$5 and the price of videos was ​$4​, what combination of pizzas and videos
valentina_108 [34]

Answer:

4 pizza and 4 videos

Step-by-step explanation:

let p represent the number of pizza

let v represent the number of videos

Total income = $40

Price of pizza = $5

Price of video = $4

Price of pizza and video = $5 + $4

= $9

Total amount spent on pizza = (5/9)* 40

= 200/9 = $22.22

Total number of pizza bought = 22.22/5 = 4.4

= 4 pizza(approximately)

Total amount spent on video = (4/9)*40 = 160/9

= 17.77

Total number of videos = 17.77/4 = 4.44 = 4 videos (approximately)
