Answer;
mACB=32 degrees
Explanation;
If the measure of the arc is 64 and you are finding the measure of an inscribed angle (ACB) then you divide by two.
<ACB is an inscribed angle whose intercepted arc, AB, measures 64°. Since an inscribed angle is measured by 1/2 the measure of its intercepted arc, the measure of <ACB is (1/2)(64°) = 32°
average distance between variable scores and the mean in a set of data
Explanation:
Standard deviation refers to the average distance between the variable scores and the mean in a set of data.
The standard deviation is one of the measures of dispersion used in statistically analysis of a given data set.
To calculate standard deviation, we used the mean of data sets and each of the data points.
It is also known as the root-mean square deviation
