Answer:
The distance between point A and point B is 12 units.
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-8 - 4)² + (6 - 6)²
d = √144 + 0
d = 12
Similar triangles so AC:BC=AE:DE
15+6=21 = AE
15:12.5=21:?
to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side
21/15=1.4
1.4 x 12.5=17.5
So DE=17.5
Answer:
The answer is 3
Step-by-step explanation:
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.
