It would be: 12/15 = 4/5
In short, Your Answer would be 4/5
Hope this helps!
The slope will be the difference between the y-coordinates divided by the difference between the x-coordinates:
then the slope of the line is:
Hello,
Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2
Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4
One other way:
y=9-1/2 x²
y'=-x
gradient 1=-(-2)=2 for point (-2,7)
gradient 2=-(4)=-4 for point(4,1)
The ratio of the difference of the two means to Sidney’s mean absolute deviation is; 4/3.28
<h3>How to find the Mean Absolute Deviation?</h3>
From the given table, we see that;
Mean grade of Sidney = 82
Mean grade of Phil = 78.
Mean absolute deviation of Sidney = 3.28
Mean absolute deviation of Phil = 3.96.
The difference between the two means of Sidney and Phil = 82 - 78 = 4.
Thus, the ratio of the difference of the two means to Sidney’s mean absolute deviation is; 4/3.28
Complete Question is;
The means and mean absolute deviations of Sidney’s and Phil’s grades are shown in the table below. Means and Mean Absolute Deviations of Sidney’s and Phil’s Grades Sidney Phil Mean 82 78 Mean Absolute Deviation 3.28 3.96 Which expression represents the ratio of the difference of the two means to Sidney’s mean absolute deviation?

Answer:
9:29 PM
Step-by-step explanation:
Let us add the number of minutes the first act, interval and second act lasted:
46 + 20 + 53 = 119 minutes
Converting this to hours and minutes:
60 minutes = 1 hour
119 minutes = 1 hour 59 minutes
Therefore, the time that the second act ends is:
H M
7 : 30 PM
+ <u> 1 : 59</u>
<u> 9 : 29 </u>
<u />
The second act will end by 9:29 PM
