(2x-10)/4 = 3x
2x - 10 = 12x
10x = -10
x = -1
Answer:
The correlation coefficient is r = 0.52
Step-by-step explanation:
From the question we are told that
The correlation coefficient is r = 0.52
Generally correlation has no unit and is not affected by unit (i.e it show the ratio between two quantities )
Hence a change of the unit of measurement of length from cm to mm will not affect the correlation coefficient r hence the value will still remain r = 0.52
Answer:
<em>The zero of the line is (2,0)</em>
Step-by-step explanation:
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:
We are given the points (1,-3) and (4,6). Substituting:
Operating:
The zero of this line can be found by making y=0 and solving for x:
0+3=3(x-1)
3=3x-3
Adding 3:
6=3x
Solving:
x = 2
The zero of the line is (2,0)
Answer:
9 shots
Step-by-step explanation:
This is a box and whisker plots. They are formatted like this:
The two dots on the end are the minimum value and the maximum value. (2 is the minimum, 16 is the maximum).
The two ends of the box are the quartiles. (1st quartile is on the left, 3rd is on the right)
And in the middle, where the line cuts through, that is the median of the data set (aka the 2nd quartile).
We can see that the line cutting through the box is on the point 9, meaning the median is 9.
Hope this helped!
Answer:
4
Step-by-step explanation:
since the fraction is 1/4 you can multiply 4 by 4 and get sixteen and 4x1=4
