Given:
The pair of points.
5. P(1, 1), Q(–1, –1)
6.
To find:
The distance between the pair of points.
Solution:
Distance formula:
5.
The distance between the pair of points P(1, 1) and Q(–1, –1) is:
Therefore, the distance between P and Q is .
6.
The distance between the pair of point is:
On further simplification, we get
Therefore, the distance between E and F is 6.5 units.
The mean score for the six students is the sum of the scores divided by the number of students = (650+550+380+720+710+550)/6 =3560/6=593.33
If they are representative of all the class then, te point estimate of the mean score for the studens is 593.33
