the large Square above has area 9 is divided into 9 smaller squares of equal area what is the length of how strong and bold

Answers

If one square is divided into 9 smaller equal squares, then they have to be arranged in 3 lines of 3, that is 3 smaller equal squares per side of the original big square. That said, the area of the big square is equal to the multiplication of 3 small squares sides times 3 small squares sides, call x the length of the small squares.
So,
area = 9 = 3x*3x
9x^2 = 9
x^2 = 1
x = 1
therefore the smaller squares have sides of 1 unit

Which of the following statements about the median is not true? ______ A) It is a measure of central tendency. B) It is equal to the mode in bell-shaped ""normal"" distributions. C) It is more affected by extreme values than the arithmetic mean. D) It is equal to Q2.

Answers

Answer:  Choice C

It is more affected by extreme values than the arithmetic mean

Explanation

The median is not affected by outliers. In fact, whenever there are outliers, the median is the better measures of center. For instance, housing prices use the median home value because some multi-million dollar mansions positively skew the distribution. These few and large outliers pull on the mean to make it larger than it should be. On the other hand, the median is not affected by this pull.

This is why choice C is a false statement, and it's the final answer.

Choices A, B, and D are true statements. This allows us to rule them out.
