Find the median of the following set of data:100,40,200,20

Median=(n+1/2)th item

Now,

4+1/2

=2.5

Again,

2nd item+(3rd - 2nd item) *0.5

40+(200-40)*0.5

40+160*0.5

40+80

120

Therefore, Median =120

it is not that hard all u have to do is plot the graph

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
