Answer:

Step-by-step explanation:
We want to find the coordinates of a certain point C(x,y) such that C divides
and
in the ratio m:n=3:2
The x-coordinate is given by:
The y-coordinate is given by:
AB has coordinates A(-5,9) and B(7,- 7)
We substitute the values to get:
and
Therefore C has coordinates
The line segment that contains C is

Let us do it by converting the 0.4 to a fraction, it has one decimal, so we'll use one zero at the denominator.
and 9.21 to a fraction as well, two decimals, thus two zeros at the denominator then,
Answer:

Step-by-step explanation:
As the mean is 20.2 and the standard deviation is 2.4
The range within the first standard deviation is
(17.8,22.6)
This means that we can safely use the range of (18,22) as we cannot confirm whether the other values fall within the range.
Within this range there are
