The statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.

<h3>What is a survey?</h3>

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have an automotive service centre would like feedback on its customer service each customer receives a printed card after they pay for services with a short survey on which customer service is ranked on a scale from 1  to 5.

From the data given we can say, not everyone will choose to leave a review when leaving the store, and those who do will have been inconvenienced in some way and felt compelled to do so, while the rest of the customers left and went about their business.

Thus, the statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.

Answer:

  • rectangular prism: 288 ft³
  • triangular prism: 72 ft³
  • total: 360 ft³

Step-by-step explanation:

The volume of a rectangular prism is given by the formula ...

  V = LWH . . . . . the product of length, width, height

This rectangular prism has a volume of ...

  V = (12 ft)(6 ft)(4 ft) = 288 ft³ . . . . rectangular prism volume

__

The volume of a triangular prism is found from the formula ...

  V = Bh

where B is the area of the triangular base, and h is the height of the prism (distance between the triangular bases). The triangular base area is found from ...

  A = 1/2bh . . . . .where b is the base of the triangle, and h is its height.

Here, we have ...

  B = 1/2(6 ft)(4 ft) = 12 ft²

  V = Bh = (12 ft²)(6 ft) = 72 ft³ . . . . triangular prism volume

__

The total volume of the given geometry is the sum of the volumes of the parts:

  aquarium volume = 288 ft³ +72 ft³ = 360 ft³

Using the quadratic formula, what is the value of x for x^2-4+5=0​
PSYCHO15rus [73]

value of x is: x= i and x= -i

Step-by-step explanation:

We need to find the value of x from x^2-4+5=0​ using quadratic formula.

The term is: x^2+1=0​

The quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\

Where a = 1, b=0,c=1

Putting values:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{0\pm\sqrt{(0)^2-4(1)(1)}}{2(1)}\\x=\frac{\pm\sqrt{-4}}{2}\\x=\frac{\pm2i}{2}\\x=\pm i

So, value of x is: x= i and x= -i
