The following function is probability Distribution function.
Rina8888 [55]

Answer:

9.60 ; - 60.96

Step-by-step explanation:

Given the function :

F(x)=6(x+1) /25, x=0, 1, 2, 3, 4.

x = 0

F(0)=6(0+1)/25 = 6/25 = 0.24

x = 1

F(1)=6(1+1)/25 = 12/25 = 0.48

x = 2

F(2)=6(2+1)/25 = 18/25 = 0.72

x = 3

F(2)=6(3+1)/25 = 24/25 = 0.96

x = 4

F(2)=6(4+1)/25 = 30/25 = 1.2

X ______0 _____ 1 ______ 2 ______ 3 ____ 4

P(x) ___ 0.24 __ 0.48 ___ 0.72 ____ 0.96 __ 1.2

Mean, μ = Σx*p(x) :

(0*0.24) + (1*0.48) + (2*0.72) + (3*0.96) + (4*1.2)

= 9.60

Variance : Σx²*p(x) - μ²

(0^2*0.24) + (1^2*0.48) + (2^2*0.72) + (3^2*0.96) + (4^2*1.2) - 9.6^2

= 31.2 - 92.16

= - 60.96

The area of a rectangle is 44 square feet. The base of the rectangle is 11. Find the height, then find the perimeter
Alecsey [184]

Answer:

4

Step-by-step explanation:

Since the area of a rectangle = Length times Breath

We are just going to divide your are by breadth which is

Let your length become y

= y × 11 = 44

to get your answer you move× 11 over the equal to sign which becomes ÷11 because any sign that cross the equal to sign changes which is equal to

y = 44÷11

y = 4

what i did was that i divided 44 by 11 which is equal to 4
