the perimeter is 68.8cm
Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4 =16 x W
then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get
Answer:
For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.
And this value was calculated with a sample of n =1000 people.
And X for this case is 450, because 0.45*1000=450
The real interest is on the population proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
Step-by-step explanation:
Assuming the following question : "Give the relevant proportion using correct notation. Your answer should be an expression composed of symbols: A recent headline states that 45% Think Children of illegal inmigrants Should Be Able to Attend Public School. The report gives the results of a survey of 1000 randomly selected likely voters in the US."
For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.
And this value was calculated with a sample of n =1000 people.
And X for this case is 450, because 0.45*1000=450
The real interest is on the population proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
