By similar triangle s
X/25 = 16/x
X^2 = 25*16 = 400
X = 20 answer
Answer:
62.5
Step-by-step explanation:
From the question, we ware told that triangle ABC is similar to XYZ
Hence Aabc/Axyz = AB/XY
Substitute the given values
25/16 = AB/40
Cross multiply
16AB = 40 * 25
16AB = 1000
AB = 62.5
<em>Hence the length of AB is 62.5</em>

Step-by-step explanation:
Pearson mode skewness, also called Pearson's first coefficient of skewness, is a way to figure out the skewness of a distribution. The mean, mode and median can be used to figure out if you have a positively or negatively skewed distribution. If the mean is greater than the mode, the distribution is positively skewed.
