3! (Three factorial) is the same as 3 • 2 • 1. So 3! = 6
Answer:1. find the intersection, 2.) 0 and 1, 3,) 2 and 3, 4.) 0.4, 2.8
Step-by-step explanation:
Answer:
Average consumption ( mean ) = 9
MOE = 4
Step-by-step explanation:
We know that
CI ( 5 ; 13 )
and CI [ μ - MOE ; μ + MOE ]
From the above relations we get
μ - MOE = 5
μ + MOE = 13
Adding member to member these two equations we get
2*μ = 18
μ = 9 and MOE = 13 - 9
MOE = 4
The number is 20. 20+10 (half of 20) + 4 (a fifth of 20) = 34
