8Z = 64
Divide both sides by 8.
8Z/8 = 64/8
Z = 64/8
Z = 8
Your final answer is B. 8.
Answer:
- 1800 ; 4284.8579 ;
Step-by-step explanation:
Given the table :
Outcome _____ probability
-12000 ________ 0.15
__ 0 __________ 0.85
Expected loss, m: Σx*p(x)
(-12000 * 0.15) + (0 * 0.85)
-1800 + 0 = - 1800
Standard deviation = sqrt(Var(x))
Var(x) = Σx²*p(x) - m²
(-12000^2 * 0.15) + (0^2 * 0.85)] - 1800^2
21,600,000 - 3240000
= 18360000
Standard deviation = sqrt(18360000)
Standard deviation = 4284.8579
Answer: 4(×+1) (×-1)
Step-by-step explanation:
Answer:
53 1/3 miles.
Step-by-step explanation:
Well the eagle would take 1 1/3 of an hour to fly 40 miles, so you multiply 1 1/3 to 48 to get your answer.
