In a survey of 350 students of a school 200 liked pkr 220 liked chit wan and 120 like both the places 1. Show the above information ina Venn diagram
2. Find the number of students who like neither of 2 places
3. Find the number of students who liked only pkr

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

5

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

true. i hope this ! go answer some of my newest
