Answer:
2x^2 -3x +10
Step-by-step explanation:
2(x^2 + 5) − 3(x + 1) + 3
Distribute
2x^2 +10 -3x -3 +3
Combine like terms
2x^2 -3x +10 -3+3
2x^2 -3x +10
Answer:
Standard error of mean = 689
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $28,520
Standard Deviation, σ = $5600
Mean of sampling distribution =
As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.
Sample size, n = 66
Since the sample size is large, we can use normal distribution for approximation.
Standard error of mean =
Answer: more than 1/2
Step-by-step explanation: 1/2 equals 2/4 so 3/4 is more.
Well, we know that 2/3 is about equal to .666 and 2/4 equals .5 Since .666 is a greater number, Ricardo read more.
