C, this class is really hard, if u need tutoring contact me
<u>Answer-</u>
<em>About </em><em>4 points</em><em> should be below the trend line.</em>
<u>Solution-</u>
A Scatter Plot has points that shows the relationship between two sets of data.
A line of best fit or trend line is a straight line that best represents the data on a scatter plot.
This line may pass through some of the points, none of the points, or all of the points.
But its objective is to have the line as close as possible to all points, and as many points above the line as below.
As there are 4 points above the trend line, so there should be 4 points below that.
Answer:
x = 2; y = 3; z = 1
Step-by-step explanation:
For the first fertilizer (A) we can form the equation:
y + 2z = 5
For the second fertilizer (B) we can form the equation:
x + 2y + 5z = 13
For the third fertilizer (C) we can form the equation:
x + 2z = 4
solving simulteneously:
y = 5 - 2z
x = 4 -2z
Substituting (i) and (ii) into (2)
4 - 2z + 10 -4z + 5z = 13
14-z =13, therefore z = 1
substituting z into (i) and (ii)
y = 3
x = 2
Mean (average) can be found by adding up all the numbers and then dividing that by how many numbers there are.
(5+10+12+4+6+11+13+5) / 8 = 66/8 = 8.25 <==
the mode (the number used most often) = 5....just so u know, there doesn't have to be a mode, and sometimes there is more then 1 mode. But for this one, the mode is 5. <==
median (the middle number)...for this, u put the numbers in order...
4,5,5,(6,10),11,12,13
now start moving from both ends going inward until u find the middle number...keep in mind, when u have an odd number of numbers, u will have 1 middle number.....but when there is an even number of numbers, like in this case, u will have 2 middle numbers...so u take ur 2 middle numbers, add them, then divide by 2 to get ur median.
median = (6 + 10) / 2 = 16/2 = 8 <==
Answer: The first one (A) f(x)= x (x-a)(x-b)²
