81,27, 9, 3, 1 just guess
Quadratic trinomial is the answer because the exponent is 2
Answer:
65
Step-by-step explanation:
median = (N+1)/2
=(100+1)/2
= 50.5
cf just greater than 50.5 is 65 .So, median is 65.
Answer:In order to specify a line completely, all you need is
Step-by-step explanation:
co-ordinates of any one of the points it passes through (say, (x1,y1) ), and
its inclination (slope = m).
Its equation, by virtue of the definition of the slope then becomes,
y−y1x−x1=m
Whence, for our case,
y−2x+6=−12
which simplifies to
x+2y+2=0
