Find x. Assume that segments that appear tangent are tangent.

1 answer:

6 0

Assuming that CB is tangent, this is just a right triangle with a hypotenuse of 20 and a side of 12 so by the Pythagorean Theorem:

20^2=12^2+x^2

400=144+x^2

x^2=400-144

x^2=256

x=16

Suppose a population has a mean weight of 180 pounds and a standard deviation of 25 pounds. a sample of 100 items is drawn from

Angelina_Jolie [31]

Solution: We are given:

μ=180,σ=25,n=100

Therefore the standard error of the mean is

$\frac{standard deviation}{\sqrt{n}}$

$\frac{25}{\sqrt{100}}$

$2.5$
