Answer:
The answer is below
Step-by-step explanation:
1)
mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65
Given that the confidence level (c) = 90% = 0.9
α = 1 - c = 0.1
α/2 = 0.05
The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65
The margin of error (E) is given as:
The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)
2)
mean (μ) = 23, SD(σ) = 12, sample size (n) = 45
Given that the confidence level (c) = 88% = 0.88
α = 1 - c = 0.12
α/2 = 0.06
The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56
The margin of error (E) is given as:
The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)
Answer:
f(3) = -10
g(-3) = 86
Step-by-step explanation:
You just fill in 3 where the x is in the f(x) equation and -3 into the x in the g(x) equation. I hope this helps!
The answer is 24 (I think). 62-14=48÷2=24
Answer:
The main difference between the fixed quantity and fixed time period is that the fixed quantity makes it mandatory for a fixed number of items to be ordered every time an order is made, while the fixed time period has a fixed period orders are received before the next order period.
Step-by-step explanation:
The fixed quantity model is adopted by producers of a product to maintain a package type and also to maximize the profit derived from sales. For example is when ordering or buying eggs from a store, the buyer cannot purchase five eggs since it is packaged in a dozen (12), and so must buy the whole package.
The fixed time model uses time intervals to receive and accumulate orders before delivery is made for every order interval.
Answer:
A. 3
Step-by-step explanation:
In a function, the inputs do not repeat.
The inputs are assigned to exactly one output for each.
Three is one of the options. Three is already an input in the given function.
Replacing the ? with 3 would create the non-function.
(3,5) (2, 4) (9, 0) (3,6)
Option A should be the correct answer.
Hope this helps.
