Answer with explanation:
Ques 1)
We know that the range of a data set is the difference between the maximum and the minimum value.
We are given a data set as:
45 93 60 72 15 45 81
on arranging the data in the increasing order we get:
15 45 45 60 72 81 93
Minimum value=15
Maximum value=93
Range=Maximum value-Minimum value
Range=93-15
Range=78
Ques 2)
We are given data point as:
63 54 62 59 52
on arranging the data in the increasing order we have:
52 54 59 62 63
The mean of data is calculated as:
Now we calculate variance
Let mean be denoted by x'
x-x' (x-x')²
52-58= -6 36
54-58= -4 16
59-58=1 1
62-58=4 16
63-58=5 25
∑ (x-x')²=94
Now, variance is:
Variance=∑ (x-x')²/5
=94/5
= 18.8
Hence, variance is: 18.8
Ques 3)
We are given Variance=88
As standard deviation is the square root of variance.
Hence,
standard deviation=√88
=9.38
Ques 4)
We arrange the data in the increasing order as:
4 4 5 5 5 6 9
Now mean of the data is:
(x-x') (x-x')²
-1.43 2.04
-1.43 2.04
-0.43 0.18
-0.43 0.18
-0.43 0.18
0.57 0.32
3.57 12.74
∑ (x-x')²/7=17.68/7=2.52
Hence Variance=2.52
Now standard deviation is the square root of variance.
Hence standard deviation=√2.52=1.6
Ques 5)
The box and whisker plot is attached to the answer.

answer:
The equation of line s is given as y = 2. To find the coordinates of point C of AA'B'C' for Rs, we need to consider the intersection of line s with the x-axis.
When the equation of a line is in the form y = c, where c is a constant, it represents a horizontal line parallel to the x-axis. In this case, the line y = 2 is a horizontal line passing through the y-coordinate 2.
Since the line y = 2 does not intersect the x-axis, there is no point of intersection, and we cannot determine the coordinates of point C.

Area = Wide x Length
Wide: x + 5
Long: 3x - 2
Area = (x + 5) x (3x - 2)
Area = 3x² - 2x + 15x - 10
Area = (3x² + 13x - 10) square feet
