Answer:

\hat p =\frac{14}{250}= 0.056

And for this case that represent the 5.6% of the homeless persons who are veterans

Step-by-step explanation:

We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

\hat p =\frac{X}{n}

The last one is an unbiased estimator of the true population proportion p

And replacing the info given we got:

\hat p =\frac{14}{250}= 0.056

And for this case that represent the 5.6% of the homeless persons who are veterans

How do I find the inverse function of this equation
trapecia [35]

Answer:

y=ln(x/(1-x))

Step-by-step explanation:

y=e^x/(1+e^x)

Cross multiply

y(1+e^x)=e^x

Distribute

y+ye^x=e^x

Put anything with x on with side and everything without x on opposing side:

y=e^x-ye^x

Factor right hand side

y=(1-y)e^x

Divide both sides by (1-y)

y/(1-y)=e^x

Use natural log.

ln(y/(1-y))=x

The inverse is

y=ln(x/(1-x))

HD Straight line graphs
Taya2010 [7]

Answer:

The equation of the sraight line  3x- y+ 6 =0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the gradient of the function

   |gradf| = 3  and point (-1,3)

Given that the slope of the line

 m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

y -y_{1} = m(x-x_{1} )

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

<u><em>Final answer:-</em></u>

The equation of the sraight line  3x- y+ 6 =0

<u><em></em></u>
