Step-by-step explanation:
in a survey of 100 people ,65 read Kantipur ,45 read Gorkhapatra, 40 read himalayan times dream,25 read Kantipur as well as Gorkhapatra ,20 read kantipur as well as himalaya times,15 read gorkhapatra,as well as himalaya times and 5 read all three news papers.
1)draw a Venn diagram to illustrate the above information.
2find how many people do not read all three news paper ?
Answer:
2/5
Step-by-step explanation:
Add up everything which would be 15, then put the number of ovens their was as the numerator. Then you'd have 6/15 so then just simplify!
What best describes the range of possible values for the third side of the triangle are
- If the 3rd side is less than 6, it could never reach between the ends of the 10 and the 16.
- If the 3rd side is more than 26, then the 10 and the 26 could never reach its ends.
This is further explained below.
<h3>What is the range?</h3>
Generally, After removing the sample maximum and lowest, we get the range of the data set. It shares the same measurement systems as the data.
In conclusion, Choose the options that best characterize the interval across which the third side may take on a value;
When the 10 and 16 are placed end to end, the third side can never be shorter than 6.
If the sum of the 10 and the 26 is more than the third side's value, then the 10 and the 26 will never sum to the side's value.

X*a = 244 is equation (1)
x+a = 2 is equation (2)
Solve equation (2) for 'a' to get
x+a = 2
a = 2-x
Call this equation (3)
We will plug equation (3) into equation (1)
x*a = 244
x*(a) = 244
x*(2-x) = 244
Notice how the 'a' is replaced with an expression in terms of x
Let's solve for x
x*(2-x) = 244
2x-x^2 = 244
x^2-2x+244 = 0
If we use the discriminant formula, d = b^2 - 4ac, then we find that...
d = b^2 - 4ac
d = (-2)^2 - 4*1*244
d = -972
indicating that there are no real number solutions to the equation x^2-2x+244 = 0
So this means that 'x' and 'a' in those two original equations are non real numbers. If you haven't learned about complex numbers yet, then the answer is simply "no solution". At this point you would stop here.
If you have learned about complex numbers, then the solution set is approximately
{x = 1 + 15.588i, a = 1 - 15.588i}
which can be found through the quadratic formula
Note: it's possible that there's a typo somewhere in the problem that your teacher gave you.
