Valentin [98]3 years ago
5 0

Answer:

Step-by-step explanation:

mean = sum of data / no of data

= 4+7+5+9+11+6 /6

=42 / 6

=7

mean = 7

to find median arrange the data from ascending to descending order

Data = 3,4,6,8,10,12

median = (N +1) /      (N means no of data)

=(6 +1) / 2

=7/2

=3.5

= 3 rd term + 4 th term / 2

=6 + 8 / 2

=14 / 2

=7

median = 7

The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear and the line has a slope of _____.
Anon25 [30]

If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

PQ → (0, 3), (2, 0).

Substitute:

m=\dfrac{0-3}{2-0}=\dfrac{-3}{2}=-1.5

QR → (2, 0), (4, -3).

Substitute:

m=\dfrac{-3-0}{4-2}=\dfrac{-3}{2}=-1.5

CORRECT :)

<h3>Answer: m = -1.5.</h3>
