Identify the center and the radius of each.<br><br> x^+y^+26x-22y+281=0
inessss [21]

Answer:

Center (-13,11) , radius 3

Step-by-step explanation:

The given circle has equation

x^2+y^2+26x-22y+281=0

We compare this to the general equation.

x^2+y^2+2ax+2by+c=0

where (-a,-b) is the center.

This implies that;

2a=26

\Rightarrow a=13

2b=-22

b=-11

The center is therefore (-13,11)

The radius is given by

r=\sqrt{a^2+b^2-c}

r=\sqrt{13^2+(-11)^2-281}

r=\sqrt{9}

The radius is 3

Effectus [21]

Answer:

The value of the test statistic is of 0.22.

Step-by-step explanation:

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected mean, \sigma is the standard deviation(square root of the variance) and n is the size of the sample.

A lumber company is making boards that are 2920.0 millimeters tall.

This means that \mu = 2920.

A sample of 12 is made, and it is found that they have a mean of 2922.7 millimeters with a variance of 121.00.

This means that X = 2922.7, n = 12, \sigma = \sqrt{121} = 11. So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{2922.7 - 2922}{\frac{11}{\sqrt{12}}}

t = 0.22

The value of the test statistic is of 0.22.
