Answer:
Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase.
Step-by-step explanation:
In this question, we need to tell some things that could help to check if two polygons are scaled copy of each other or not.
Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase. For example, if a rectangle has a length of 10 and a height of 8, a scaled copy would be a length of 5 and a breadth of 4.
Another example is as follows:
If a rectangle has a length of 4 and a height of 3, a scaled copy would be a length of 8 and a breadth of 6.
Answer:
Sample is biased
Step-by-step explanation:
In her experiment, Gloria assumes that the reading habits of the students in her school district are exactly the same to that of students in all state schools. This assumption is unlikely to be true and, therefore, this statistic is misleading because the sample used is biased.
From her data, all Gloria can do is report the percentage of students that read more than one book per month in her school district.
The answer would be 100
90+90+130+130=440.
540 - 440 = 100.
