Can you add the price of the tickets?
Answer:
<h3>-π/12</h3>
Step-by-step explanation:
Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12
180 degrees = πrad
-15 degrees = x
Cross multiply
180x = -15π
x = -15π/180
x = -π/12
Hence the value of -15 degrees in radians is -π/12
Mrs. Potter’s class was more consistent because their standard deviation of 3 points was lower.
<h3>What is a
statistical dispersion?</h3>
A statistical dispersion is also referred to as degree of dispersion and it can be defined as a measure of the extent to which a numerical value (data) is likely to vary about a mean or an average value.
In Mathematics, there are four measures of dispersion for a data set and these include the following:
In this scenario, we can infer and logically conclude that Mrs. Potter’s class was more consistent than Mr. Jones class because their standard deviation of 3 points was lower.
