Step-by-step explanation:
r+58
Let r=3
3+58
61
D Mean is 7 and median is 7
Mean refers to the average of the a given set of data. This is obtained by adding all the data and dividing it to the number of data sets. The mode is the most frequently occurring digit in a data set while the median is the middle number when you arrange the data from lowest to highest or vice versa.
We know that
Any point <span>(x,y)</span> on the parabola is equidistant from the focus and the directrix
Therefore,
focus (0,4) and directrix of y=2
<span>√[<span>(x−0)</span></span>²+(y−4)²]=y−(2)
<span>√[x</span>²+(y-4)²]=y-2
x²+(y-4)²=(y-2)²
x²+y²-8y+16=y²-4y+4
x²=4y-12-----> 4y=x²+12----->y= (x²/4)+3
the answer is
y= (x²/4)+3
