The answer is 2x-26
1+2x-27 9*3= 27
1-27+2x You would combine like terms here
2x-26
5>x because you can subtract 5 from both sides and 3x from both sides
Answer:
A) 2.6 mm Hg
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
n > 30, so we can approximate CV with a normal distribution. At P = 94%, CV = 1.88.
SE = σ / √n
SE = 13.5 / √92
SE = 1.41
So the margin of error is:
ME = 1.88 × 1.41
ME = 2.6
