18.87 inches the cube root of 6720
Answer:
Step-by-step explanation:
Answer:
$17.90 rounded up to 2dp
Step-by-step explanation:
11 = 60%
19 = 25%
16 = 15%
Total 3 hrs = $46 where average is 46/3 = 15.33 when same percentage of hours. For 10% higher which is 25% we take 19 x 0.10 = 1.533 and subtract = $17.47 for 25% - 40% of time in employment, but for 50% we find the average taking 11 x 0.45 = 6.8985 and add = $ 11 + 6.8985 = 17.8985 = $17.90
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% (.
