musickatia [10]

Answer:

a) 0.567

b) (0.5414,0.5926)

c) (0.5364,0.5976)                  

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1007

Number of respondent that  they will be able to afford health insurance in the future, x = 571

a)  point estimate of the population proportion

\hat{p} = \displaystyle\frac{x}{n} = \frac{571}{1007} = 0.567

b) 90% Confidence Interval.

\hat{p} + z_{\text{critical}}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64

Putting values, we get,

0.567 \pm 1.64\times \sqrt{\dfrac{0.567(1-0.567)}{1007}}\\\\0.567 \pm 0.0256=(0.5414,0.5926)

c) 95% Confidence Interval.

\hat{p} + z_{\text{critical}}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96

Putting values, we get,

0.567 \pm 1.96\times \sqrt{\dfrac{0.567(1-0.567)}{1007}}\\\\0.567 \pm 0.0306=(0.5364,0.5976)

Let f = {(x, y) ∈ R × R | xy = 2x + y + 1} There is at least one x ∈ R with no y ∈ R. Find all such problematic x ∈ R. Then rest
loris [4]

Answer:

Problematic x is x = 1

Step-by-step explanation:

Equation:

xy= 2x + y + 1

xy - y = 2x + 1

y(x-1) = 2x + 1

y = (2x+1)/(x-1)

The problematic x is such that when the denominator of the function is 0

x - 1 = 0

x = 1 (the problematic x)

So the domain of f is: x is the subset of R (real number) with the exception of x =/ 1 (x not equal to 1)

To prove this, we can plot the graph and in the graph we can see that as the value of x approaches from negative values to 1, y value will approaches negative infinity, and as the value of x approaches from large positive numbers, y value approaches infinity.

In other words, we'll see an assymptote at x=1

To prove that it is a function, we can do vertical line test by drawing vertical lines accross the graph. We'll see that each line crosses the equation line once hence proving the equation as a function
