Answer:
Use quadratic regression on your calculator.
See my graph below.
Find u, v , u , v , and d(u, v) for the given inner product defined on Rn. u = (0, −4), v = (5, 3), u, v = 3u1v1 + u2v2

Answer:


Step-by-step explanation:
We are given that inner product defined on 

u=(0,-4),v=(5,3)
We have to find the value of <u,v> and d(u,v)
We have 
Substitute the value then we get

Now, 
Using this formula we get


Not sure what do with the other numbers? Like the -2/5
Maybe put them instead of the 2/3?
Answer:
Step-by-step explanation:
Given that a nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks
90% confidence interval is
(317.2, 326.8)mg.
Using confidence intervals,we can check whether null hypothesis is true.
Here

(left tailed test at 10% significance level)
We check whether confidence interval 90% contains the mean value.
We find 325 belongs to the confidence interval
Hence H0 is true
The hot dogs do not satisfy.
