Sid walked 6 miles, which is 3/5 of the total distance.
Divide 6 with 3
6/3 = 2
2 miles is the walking distance for 1/5
Multiply 5 to both sides
2 (x 5) = 1/5 (x 5)
10 = 1
The total distance is 10 miles

<span>E[Y] = 0.4·1 + 0.3·2 + 0.2·3 + 0.1·4 = 2
E[1/Y] =0.4·1/1 + 0.3·1/2 + 0.2·1/3 + 0.1·1/4 = 0.4 + 0.15 + 0.0666 + 0.025?0.64
V[Y] =E[Y2]-E[Y]2= (0.4)·12+(0.3)·22+(0.2)·32+(0.1)·42-22= 0.4+1.2+1.8+1.6-4= 5-4 = 1</span>
Answer:
(f•g)(4) = 45
Step-by-step explanation:
f(x)=4x+1
g(x)=x^2-5
(f•g)(x) = 4(x^2 -5)+1
(f•g)(4) = 4(4^2 -5)+1
(f•g)(4) = 4(16-5)+1
(f•g)(4) = 4(11)+1
(f•g)(4) = 44 + 1
(f•g)(4) = 45
