<h2>Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0</h2>

Step-by-step explanation:

Equation of circle with (h,k) as center and radius r is given by,

          (x-h)²+(y-k)² = r²

Here we need to find equation for a circle with center (0, −4) and radius 8.

Center = (h,k) = (0, −4)

Radius = r = 8

Substituting in equation

              (x-h)²+(y-k)² = r²

               (x-0)²+(y-(-4))² = 8²

               x²+(y+4)² = 64

                x²+y²+8y+16 = 64

                x²+y²+8y-48 = 0

Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0

the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake is 3.7

<u>Step-by-step explanation:</u>

Here we have , to find  the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake . Let's find out:

We know that , Value of earthquake is given by formula

⇒ M = Log(\frac{I_1}{I_0} ) , Where M is magnitude of earthquake

I_1  is the measured magnitude of intensity of  earthquake .

I_0  is the standard magnitude of intensity of  earthquake .

According to question , I_1 = 5011I_0 , Hence

⇒ M = Log(\frac{I_1}{I_0} )

⇒ M = Log(\frac{5011(I_0)}{I_0} )

⇒ M = Log(5011 )

⇒ M =3.69924    { On rounding off we get }

⇒ M =3.7

Therefore , the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake is 3.7

FinnZ [79.3K]

Answer:

We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.

Step-by-step explanation:

Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.

In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.

Confidence Interval can be calculated using M±ME where

  • M is the sample mean difference between Store A and Store B purchase amounts
  • ME is the margin of error from the mean
