Which is an example of qualitative data?

spayn [35]

Answer:

B

Step-by-step explanation:

To answer this question, we have to familiar with the characteristics of qualitative data. Qualitative data is a type of data that is OBSERVED not measured. It corresponds to qualities of something. Qualitative data cannot be expressed in numerical form. It is usually collected through observation methods or interviews.

So from the above options,

Option A

The price of the last set of tires is a measurable quantity which can be expressed in numerical form. So it would not be the answer.

Option B:

The appearance of tires is a quality which can only be seen or observed but cannot be expressed in numerical form so it is the right answer for the question.

Option C & D:

The number of miles is a numerical quantity as it is measured so it will not be the correct answer to the question.

Simple. Since a straight line is 180 you can do 180-59 in which you will get 121. You can use the alternate angle theorem.

Doug's printing business had a revenue of $6,000 and operating costs of $4,000. How much profit did his business make?

ryzh [129]

$2,000 because operating costs means how much money he needs to keep the business going and revenue is how much he makes

Assume that x equals x (t )and y equals y (t ). Let y equals x cubed plus 4 and StartFraction dx Over dt EndFraction =2 when xe

Answer:dy/dt(x=3)=54

Step-by-step explanation:

We know that we can write:

$\frac{dy}{dt}=\frac{dy}{dx} *\frac{dx}{dt}$

and so evaluate it as a product of functions, that is for a given value of x or t, we get that

$\frac{dy}{dt}(s)=\frac{dy}{dx} (s) * \frac{dx}{dt}(s)$ .

Now we are told that:

$1. x=x(t),\ 2.y=x^3+4,\ \frac{dx}{dt} =2,\ for \ x=3,$

whenever it happens, this means the influence of t is hidden, and we only consider the result, that is, how much is x when the derivative has the value of 2, we are not concerned for what value of t it happens, since we get all the necessary information beforehand.

Now we need to calculate

$\frac{dy}{dx}=3x^2 \rightarrow \frac{dy}{dx}(3)=3(3)^2=27$ .
