HELP PLEASE ASP !!!! WILL GIVE BRAINLIEST <br><br> Select the slope of the line
Artist 52 [7]

Answer:

Undefined.

Step-by-step explanation:

The line given on the graph is vertical.

All vertical lines have an undefined slope.

This is because that it has no horizontal (run) change.

If you used the slope formula for the points, the denominator of the fraction will be a zero, and and you cannot divide by zero.

Hope this helps!

Brainilest is appreciated.

Given the formula A =pieab solve for a.
Romashka [77]

Answer:

a = A/πb

Step-by-step explanation:

To solve this subject of the formulae given that A = πab.

<u>solution</u>

A = πab

the next step is to look for a unique way to get rid of the variables disturbing "a" from standing alone. this variables are π and b, we need to detach dem from a

A = πab

divide both sides by πb

A/πb = πab/πb

A/πb = a

a = A/πb

therefore  the value of a in the fomular A = πab is evaluated to be  a = A/πb

A local service agency hires you to estimate the average annual income of all 700 families living in a four square block section
Digiron [165]

Answer:

The true estimate of  the average annual income of all 700 families living in a four square block section lies within the 92% confidence interval below

   34854.3  <  \mu < 35 745.7

Step-by-step explanation:

From the question we are told that

    The  sample size is  n =  50  

    The sample mean is \= x = \$ 35300

     The population standard deviation is  \sigma =  \$ 1800

From the question we are told the confidence level is  92% , hence the level of significance is    

      \alpha = (100 - 92 ) \%

=>   \alpha = 0.08

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.751

Generally the margin of error is mathematically represented as  

      E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

=>   E = 1.751  *  \frac{1800 }{\sqrt{50} }

=>   E =  445.7

Generally 92% confidence interval is mathematically represented as  

      \= x -E <  \mu <  \=x  +E

=> 35 300 -445.7 <  \mu < 35 300 + 445.7

=> 34854.3  <  \mu < 35 745.7

So the true estimate of  the average annual income of all 700 families living in a four square block section lies within the 92% confidence interval
