The "mean" is the same thing as the "average".
To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.
If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.
If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100. So the big sum is 5,118.
Answer:
x²-10×+25=16
ײ-10×=16-25
×(×-10)=-9
but if your question is rather 2x-10×+25=16
then here goes the answers
2x-10×+25=16
-8×=16-25
-8×=-9
×=9/8
×=1¹/8
We are given with a circle and we need to find the <em>equation of the circle</em> , but first let's recall that , the equation of a circle with radius<em> 'r'</em> and centre at <em>(h,k) </em>is given by
Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here <em>(h,k) = (0,0)</em> .Which means that the centre is located at the point whose coordinates are<em> (0,0)</em> which is also known as origin . Now , finding the equation of the circle :-


<em>This is the required equation of Circle</em>
