Answer:
(a) See attachment
(b) Mara's rectangle
Step-by-step explanation:
Given
Mara
Ashton
Solving (a): Draw the rectangles
First, we need to calculate the possible dimension of both rectangles.
Area is calculated as:
For Mara
Possible values of length and width are:
This is so because:
For Ashton
Possible values of length and width are:
This is so because:
<em>See attachment for diagram</em>
Solving (b): Rectangle with bigger area
Mara's rectangle has a bigger area because
The figure is a right angle
Complementary = sum of 90 degrees
35 + 2x - 5 = 90
30 + 2x = 90
2x = 60
Solution: x = 30
1, 3, 5
You can tell by looking that her science mean is greater than her math mean.
The higher range number means that her scores in math are more varied and spread out than her science scores.
You can tell by looking that the median scores are the same.
