So the following is the answer of the following question in your problem and please do not post to many question in just one posting.
#1 The 98% confidence interval for the mean hours is between 6 and 50.
#2 The smallest margin of error between the two is southern florida with 1.8% margin of error.
Answer:
98
Step-by-step explanation:
2 (x + y) ²
= 2 (3 + 4 ) ²
= 2 x 7²
= 2 x 49
= 98
Since you didn’t specify that it needed to be y as a function of x, all of the above equalities can be rewritten as functions. However, in case that you meant to imply that, A and B are both not valid for y as a simple function of x.
Answer:
6
Step-by-step explanation:
Given
3x - 15 ≥ 3 ( add 15 to both sides )
3x ≥ 18 ( divide both sides by 3 )
x ≥ 6
Since x is greater than or equal to 6 then 6 is a solution
