Answer:
p ≥ 7/4
Step-by-step explanation:
Given :
Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.
To Find :
How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.
Solution :
Ratio of people smiled by total number of people is :
![R = \dfrac{36}{50}](https://tex.z-dn.net/?f=R%20%3D%20%5Cdfrac%7B36%7D%7B50%7D)
Now, it is given that we have to use the given conditions.
Therefore, ratio will be same :
![\dfrac{s}{650}=\dfrac{36}{50}\\\\s = \dfrac{36}{50}\times 650\\\\s = 468](https://tex.z-dn.net/?f=%5Cdfrac%7Bs%7D%7B650%7D%3D%5Cdfrac%7B36%7D%7B50%7D%5C%5C%5C%5Cs%20%3D%20%5Cdfrac%7B36%7D%7B50%7D%5Ctimes%20650%5C%5C%5C%5Cs%20%3D%20468)
Therefore, number of smiles Nathan expect to return is 468.
All circles are similar because all circle have same shape.
However Two circles are congruent , if and only if their radii are congruent.
In our question we are asked when are all circles similar given if their radii are congruent.
So we can say this statement is false because no matter the radii are congruent or not , two or more circles are always similar because of their same shape no matter what the measure of their radii is. Only if we are asked when they are congruent, we will consider the radii part.
Answer is false.
