Use a Venn diagram to answer the question. A survey of 180 families showed that 67 had a​ dog; 52 had a​ cat; 22 had a dog and a​ cat; 70 had neither a cat nor a​ dog, and in addition did not have a​ parakeet; 4 had a​ cat, a​ dog, and a parakeet. How many had a parakeet​ only?

Answers

Answer:

There are 13 families had a parakeet only

Step-by-step explanation:

* Lets explain the problem

- There are 180 families

- 67 families had a dog

- 52 families had a cat

- 22 families had a dog and a cat

- 70 had neither a cat nor a​ dog, and in addition did not have a​

 parakeet

- 4 had a​ cat, a​ dog, and a parakeet (4 is a part of 22 and 22 is a part

 of 67 and 520

* We will explain the Venn-diagram

- A rectangle represent the total of the families

- Three intersected circles:

 C represented the cat

 D represented the dog

 P represented the parakeet

- The common part of the three circle had 4 families

- The common part between the circle of the cat and the circle of the

 dog only had 22 - 4 = 18 families

- The common part between the circle of the dog and the circle of the

 parakeet only had a families

- The common part between the circle of the cat and the circle of the

 parakeet only had b families

- The non-intersected part of the circle of the dog had 67 - 22 - a =

  45 - a families

  had dogs only

- The non-intersected part of the circle of the cat had 52 - 22 - b =  

  30 - b families

  had cats only

- The non-intersected part of the circle of the parakeet had c families

  had parakeets only

- The part out side the circles and inside the triangle has 70 families

- Look to the attached graph for more under stand

∵ The total of the families is 180

∴ The sum of all steps above is 180

∴ 45 - a + 18 + 4 + 30 - b + b + c + a + 70 = 180 ⇒ simplify

- (-a) will cancel (a) and (-b) will cancel (b)

∴ (45 + 18 + 4 + 30 + 70) + (-a + a) + (-b + b) + c = 180

∴ 167 + c = 180 ⇒ subtract 167 from both sides

∴ c = 180 - 167 = 13 families

* There are 13 families had a parakeet only

Answers

Answer:

(g\ o\ f)(x) = -10x^2 + 25x + 44

Step-by-step explanation:

Given

f(x) = 2x^2 - 5x - 8

g(x) = -5x+4

Required

Find:\ (g\ o\ f)(x)

In functions;

(g\ o\ f)(x) = g(f(x))

Substitute f(x) = 2x^2 - 5x - 8 in (g\ o\ f)(x) = g(f(x))

(g\ o\ f)(x) = g(f(2x^2 - 5x - 8))

Solving for g(f(2x^2 - 5x - 8))

If g(x) = -5x+4

then

g(f(2x^2 - 5x - 8)) = -5(2x^2 - 5x - 8) + 4

Open Bracket

g(f(2x^2 - 5x - 8)) = -10x^2 + 25x + 40 + 4

g(f(2x^2 - 5x - 8)) = -10x^2 + 25x + 44

Recall that:

(g\ o\ f)(x) = g(f(2x^2 - 5x - 8))

This implies that

(g\ o\ f)(x) = -10x^2 + 25x + 44
