A randomized telephone survey of adults in the United States determines that a certain number out of 504 respondents have one or more pets. They use p^ to construct a 95% confidence interval to estimate the proportion p of American adults who have pets to be (0.56137,0.60529). How many respondents said they have one or more pets?
283
294
305
290

The critical value for 95% of confidence is

And since we know the total and the proportion is defined as:

If we solve for X (number of people who say yes) we got:

And the best answer would be:

294

Step-by-step explanation:

We know that the confidence interval for the proportion is given by:

The margin of error for the proportion interval is given by this formula:  

   (a)  

The margin of error can be calculated with this formula:

And the estimation for the true proportion is:

The critical value for 95% of confidence is

And since we know the total and the proportion is defined as:

If we solve for X (number of people who say yes) we got:

And the best answer would be:

294

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
