The heights (in inches) of males in the United States are believed to be Normally distributed with mean LaTeX: \muμ. The average

height of a random sample of twenty-five American adult males is found to be H = 69.72 inches and the standard deviation of the twenty-five heights is found to be s = 4.15. The standard error of H is = 4.15. A 90% confidence interval for ? is?

The diameter of a circle has endpoints (2,-6) and (-4,-16).
olga nikolaevna [1]

Answer:

(x + 1)^{2}  + (y + 11)^{2} = 34

Step-by-step explanation:

First find the midpoint of the segment  from (2, -6) to (-4, -16)

((2 - 4)/2, (-6 - 16)/2)

(-2/2, -22/2)

(-1, -11) is the midpoint and is the center of the circle

Now find the distance between the 2 given points and divide by 2 to get the radius of the circle

d = \sqrt{(2 + 4)^{2} + (-6 + 16)^{2}  }

  = \sqrt{6^{2} + 10^{2}  }

  = \sqrt{36 + 100}

  = \sqrt{136}

r = \sqrt{136}/2

r^{2} = 136/4 = 34

Equation of circle with center at (-1, -11) and radius = \sqrt{34} is

(x + 1)^{2}  + (y + 11)^{2} = 34

I need help in this problem
ArbitrLikvidat [17]
The equation is saying that -3x+10=5x-8. Once you get all the same terms on one side, you get 18=8x. That would end up being a decimal number, instead of a whole number. The x values would either have to be -4x or 6x in order to make the problem equal

so the volume is that of a cylinder V=hpir^2 h=8 r=2 pi=3.141592 V=8*3.141592*2^2 V=8*3.141592*4 V=32*3.141592 V=100.530944 roun
Mashcka [7]
Volume=(height)(pi)(radius^2)
Volume=(8)(3.141592)(2^2)
V=(8)(4)(3.141592)
V=(32)(3.141592)
V=100.530944
