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
X^1/2 ( x + 3) (x - 6)
= x^1/2 ( x^2 - 3x - 18)
= x^5/2 - 3x^3/2 - 18x^1/2
= (sqrt x)^5 - 3 (sqrt x)^3 - 18x^1/2
Option 1
Answer: blank number 1 would be 4, and blank number 2 would be 8. then, blank number 3 would be 3. blank number 4 would be 2,048.
Explaination:
the starting number of employees is 4, so that starts off as our base number in the first blank. we are multiplying the 4 by how many will be there in 8 years, so that's why it goes in the second blank. now, we are tripling this every year, so that goes in the 3rd blank as the exponent. multiply all that together in a calculator, and you get 2,048.
Answer:
6x-1=5x+3=8x/4=2x
Step-by-step explanation:
1944+648= 2592ft is the answer
