The answer is A because there are only acute angles
Answer:
Step-by-step explanation:
Answer: (141.1, 156.48)
Step-by-step explanation:
Given sample statistics : 


a) We know that the best point estimate of the population mean is the sample mean.
Therefore, the best point estimate of the mean weight of all women = 
b) The confidence interval for the population mean is given by :-
, where E is the margin of error.
Formula for Margin of error :-

Given : Significance level : 
Critical value : 
Margin of error : 
Now, the 90% confidence interval for the population mean will be :-

Hence, the 90% confidence interval estimate of the mean weight of all women= (141.1, 156.48)
Ok so the slashes are division so you would divide
Answer:
C. - 4x^2 + 5x - 4
Step-by-step explanation:
just expand the equation and you'll get C
