Answer:
A.
Step-by-step explanation:
A buffer must contain a weak acid and its conjugate base. There are several ways a solution containing these two components can be made: Buffers can be made from weak acids or base and their salts. ... Buffers can be made from two salts that provide a conjugate acid-base pair.
1.) 20,24,25,27,31,35,38
2.) Least value: 20 Greatest value: 38 Median: 27
3.) Lower Quartile: 24 Upper Quartile: 35
4.) Draw the first dot above 20, then a line connecting to the first line above 24, then another line above 27, then another line above the 35, then connect it to the dot that will be above 38. The lines above 24, 27,35 should make a box like the one shown at the beginning of your paper.
5.)61,63,65,68,69,70,72,74,78
6.) Least value: 61 Greatest value: 78 Median: 69 Lower quartile: 64 Upper quartile: 73
7.) Just like in number 4, plug these numbers in and create your box and whisker plot.
Hi
According to Pythagoras :
The square of hypotenuse is the sum if the square if the two other side
so : 7^2 + X^2 = 25^2
49 + X^2 = 625
X^2 = 625-49
X^2 = 576
this equation as two roots . As a triangle cannot have a negative side value, I will only take positive value
so X = V576 =24
