Answer:

Each tile covers 1/9 of a square yard. It means that you need 9 tiles to cover the bottom surface of the pool. And we know that each tile costs $3.

We have to multiply $3 by 9:

The cost:  9 * $3 = $27

Answer:

The cost of the tiles to retile the bottom of the pool is $27.

Step-by-step explanation:

1.

Choosing the product of power property,when you multiply exponentials with the same base , you add their exponents.

This is represented as :

(x^a)*(x^b)=(x^{a+b)}

This property is true in that ;

where you have x³ × x³ , x³ is x*x*x and the other x³ is x*x*x .Adding the xs will give x⁶ which is similar to 3+3=6 xs

A numerical example could be;

x^2+x^3=x^{2+3} =x^5

Answer:

N(AUC∩B') = 121

The number of students that like Reese's Peanut Butter Cups or Snickers, but not Twix is 121

Step-by-step explanation:

Let A represent snickers, B represent Twix and C represent Reese's Peanut Butter Cups.

Given;

N(A) = 150

N(B) = 204

N(C) = 206

N(A∩B) = 75

N(A∩C) = 100

N(B∩C) = 98

N(A∩B∩C) = 38

N(Total) = 500

How many students like Reese's Peanut Butter Cups or Snickers, but not Twix;

N(AUC∩B')

This can be derived by first finding;

N(AUC) = N(A) + N(C) - N(A∩C)

N(AUC) = 150+206-100 = 256

Also,

N(A∩B U B∩C) = N(A∩B) + N(B∩C) - N(A∩B∩C) = 75 + 98 - 38 = 135

N(AUC∩B') = N(AUC) - N(A∩B U B∩C) = 256-135 = 121

N(AUC∩B') = 121

The number of students that like Reese's Peanut Butter Cups or Snickers, but not Twix is 121

See attached venn diagram for clarity.

The number of students that like Reese's Peanut Butter Cups or Snickers, but not Twix is the shaded part
