Answer:
<h2>x = 54</h2>Step-by-step explanation:
The line is tangent. Therefore, the angle between the tangent and the radius is the right angle.
We know: the sum of the angles measures in a triangle is 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 126 from both sides</em>

Answer:
x = 6
Step-by-step explanation:
We want to find x,
to get x alone, we multiple both side by 10
30 divided by 5 is 6
<u>Check</u>:
We can see that 5 x ____ = 10 where ____ is 2
5 x 2 = 10
so 3 x 2 = 6

Answer:
The sampling distribution of X is centered at 15cm and the standard deviation of the X distribution is 0.0125cm.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
(a) If X is the sample mean diameter for a random sample of n = 16 rings, where is the sampling distribution of X centered and what is the standard deviation of the X distribution?
Mean:
Standard deviation:
The sampling distribution of X is centered at 15cm and the standard deviation of the X distribution is 0.0125cm.
