Remember, you can do anything to an equaiton as long as you do it to both sides
c=48y+0.99n
minus 0.99n from both sides
c-0.99n=48y
divide both sides by 48
Answer:
We would expect about 95 of the 100 confidence intervals to contain the proportion of all citizens of the United States who are optimistic about the economy.
Step-by-step explanation:
The purpose of sampling is to make statistical inference the entire population of interest. Thus, we generalized to the entire population the findings from the sample.
For instance, we don't need to drink entire cup of coffee to know whether the sugar is enough or not. We only need to stir (randomly) and take a sip from the cup of coffee. We usually assume that, if the content we sipped is satisfactory to our taste, the entire content of coffee inside the cup is satisfactory. Using this illustration, we would expect that the findings of the survey should be generalized to the entire population of study.
Thus, <em>we would expect about 95 of the 100 confidence intervals to contain the proportion of all citizens of the United States who are optimistic about the economy</em>.
Answer:
im not 100% sure but i think it is the 3 one
Step-by-step explanation:
X = 52 would be the answer you get.
Explanation you would divide both sides by 0.6 which leaves the x and by dividing 31.2 divided by 0.6 it gives you 52
The number of pairs of parallel sides of the polygon have no parallel sides if n is odd and n/2 pair of parallel sides if n is even.
<h3>What is a polygon?</h3>
The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
A regular polygon has n sides.
Then the number of pairs of parallel sides of the polygon will be
IF n is odd, then none of the sides are parallel.
If n is even, then the number of pair of parallel sides will be n / 2.
