Answer:
Blue Marlin.
Step-by-step explanation:
In any data set, mean tells about the central tendency of the data. It actually tells the average of the data. On the other hand, standard deviation tells about the spread of the data. It actually tells to what extent the observational values revolve around the mean. Mean is not a good summary statistic of any data since it does not convey the complete information. In order to understand the spread of the data, standard deviation is calculated. The smaller the standard deviation, smaller the spread of the data. It has to be kept in mind that mean has nothing to do with the spread of the data. Smaller the standard deviation, smaller the spread. In this case, lowest standard deviation is of Blue Marlin, which is 1.97. Rest of the standard deviations are larger. This means that Blue Marlin has the smallest spread!!!
Let's say each side is 5 and 5 so all you have to do is times 5 bye 5 and divide the two numbers by 20 and when you get that then you add the numbers by 180 then your answer is 239cm

Rewrite the equation in slope-intercept form:
9x - 7y = 21
-7y = -9x + 21
y = (9/7)(x) - 3
The y-intercept is where x = 0.
y = (9/7)(0) - 3
y = 0 - 3
y = -3
The x-intercept is where y = 0.
0 = (9/7)(x) - 3
3 = (9/7)(x)
21 = 9x
x = 21/9
x = 7/3
The correct answer would be C. The x-intercept would be at (7/3, 0) and the y-intercept at (0, -3). Hope that helps! :)
I confused ! I don't get what your trying to say please explain better !
