Step-by-step explanation:
You have to start out multiplying the (parentheses), then the [brackets], then the {curly brackets}. After you're done with those you would add 2.
(A) Mean best describes the amount of water in each bucket.
<h3>
What is mean?</h3>
- A dataset's mean (also known as the arithmetic mean, as opposed to the geometric mean) is the sum of all values divided by the total number of values.
- It is the most widely used measure of central tendency and is frequently referred to as the "average."
- In mathematics, particularly statistics, there are several types of means.
- Each mean is used to summarize a specific set of data, often in order to better understand the overall value (magnitude and sign) of a given data set.
- In two simple steps, we can calculate the mean or average of a data set: add up all of the values to find the sum.
- Subtract the sum from the total number of values in the data set.
Therefore, (A) mean best describes the amount of water in each bucket.

Answer:
Step-by-step explanation:
hello :
5x²+8x-4 quadratic expression when : a = 5 and b=8 and c= -4
∆ = b²-4ac ∆ = 8²-4(5)(-4) = 64 +80 = 144 = 12²
X1 = ( -b -√∆)/2a X1 = (-8-12)/10 = -20/10= -2
X2 =(-b+√∆)/2a X2 = (-8+12)/10 = 4/10 = 2/5
us factorisation : a(X-X1)(X-X2)
5x²+8x-4= 5(x+2)(x-2/5) = (x+2)(5x-2)
you can verify ; (x+2)(5x-2) = 5x²-2x+10x-4 = 5x²+8x-4
