Answer:

$x=60^{\circ}$

Step-by-step explanation:

The angle formed by $48+x$ and the angle marked as $72^{\circ}$ are co-interior angles and therefore must be supplementary (add up to 180 degrees).

Therefore, we have:

$48+x+72=180,\\x+120=180,\\x=\boxed{60^{\circ}}$

For the data set below, calculate the standard deviation to the nearest hundredth decimal place. 27 38 47 42 33 56 37 57 38 52

mihalych1998 [28]

In order to calculate standard deviation, apply the standard deviation formula, which is given in the attached file. In this formula, we are finding the square root of the sum of the square of given values less their mean value (the sum of the given numbers divided to their amount) divided to N-1, where N is the amount of the given numbers. When we calculate the mean, it is 42.7 and the standard deviation is 10.02275
