Answer:

SE = 0.025

Step-by-step explanation:

We are given;

Sample mean; x¯ = 14.52

Sample standard deviation; s = 0.075

Sample size; n = 9

Now,formula for standard error of sample mean is;

SE = s/√n

SE = 0.075/√9

SE = 0.075/3

SE = 0.025

2(x+3)^2+2(y)^2=32 what is the center point of the circle and how long is the radius
spayn [35]

Answer:

  • center (-3, 0)
  • radius 4

Step-by-step explanation:

The standard form equation of a circle is ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r

Divide your given equation by 2 to put it into standard form:

  (x +3)^2 +y^2 = 16

Comparing to the above, we see ...

  • h = -3
  • k = 0
  • r = √16 = 4

The center point of the circle is (-3, 0); the radius is 4 units long.
