in a survey it was found that ratio of people who liked modern songs and folk songs ia 8:9 out of which 50people liked both songs 40liked folk songs only and 80 liked none of the song then find the people involved in the survey

as in the question it is given that 50 people liked both songs 40 liked folk songs and 80 liked none of the song so we can add the number of people

50+40+80

170

Step-by-step explanation:

the people involved in the survey were 170

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
