Answer: The total costumers were surveyed = 500
Step-by-step explanation:
Let x = total costumers were surveyed.
Given : 125 people chose chocolate as their favorite flavor, which represents 25% of the costumers surveyed.
25% of x = 125
![\Rightarrow\ \dfrac{25}{100}\times x = 125\\\\\Rightarrow\ \dfrac{1}{4}x=125\\\\\Rightarrow\ x=125\times4\\\\\Rightarrow\ x= 500](https://tex.z-dn.net/?f=%5CRightarrow%5C%20%5Cdfrac%7B25%7D%7B100%7D%5Ctimes%20x%20%3D%20125%5C%5C%5C%5C%5CRightarrow%5C%20%5Cdfrac%7B1%7D%7B4%7Dx%3D125%5C%5C%5C%5C%5CRightarrow%5C%20x%3D125%5Ctimes4%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%20500)
Hence, the total costumers were surveyed = 500
F(5)-f (1)/5-1 gives avg over the interval
By using x-method we got that factorization
is (x+5)(x-5)
<h3>What is factorization ?</h3>
factorization is writing a expression as a product of several factors.
So Given polynomial is
![x^2-25](https://tex.z-dn.net/?f=x%5E2-25)
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
![x^2-5x+5x-25\\\\x(x-5)+5(x-5)\\\\(x+5)(x-5)](https://tex.z-dn.net/?f=x%5E2-5x%2B5x-25%5C%5C%5C%5Cx%28x-5%29%2B5%28x-5%29%5C%5C%5C%5C%28x%2B5%29%28x-5%29)
By using x-method we got that factorization
is (x+5)(x-5)

J/4 - 8 < 2
J/4 < 2 + 8
J/4 < 10 ...multiply both sides by 4
J < 10 * 4
J < 40
