that is not a function, because there are two outputs for three. two inputs can have one output, but one input cant have two outputs.
Easy:
((18-x) -5) + ((18+x)➗2)
I am not for sure how to do this just yet when I figher it out I will try to help you.<span />
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
Answer:
A: y = 9.5x + 22.5
