Answer:
-2,-6,-18
Step-by-step explanation:
let g1,g2,g3 be three G.M.s between -2/3 and -54
now -2/3,g1,g2,g3,-54 are geometric
n=5
an=a1 r^{n-1}
-54=-2/3 r^{5-1}
r^{4}=-54×-3/2=81=3^4
r=3
g1=a1×r=-2/3×3=-2
g2=a1×r²=-2/3×3²=-6
g3=a1×r³=-2/3×3³=-18
Answer:
2+3+2+2+2+3+2+2+
Step-by-step explanation:
Answer: |p-72% |≤ 4%
Step-by-step explanation:
Let p be the population proportion.
The absolute inequality about p using an absolute value inequality.:
, where E = margin of error, = sample proportion
Given: A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .
|p-72% |≤ 4%
⇒ 72% - 4% ≤ p ≤ 72% +4%
⇒ 68% ≤ p ≤ 76%.
i.e. p is most likely to be between 68% and 76% (.
