What is a statistical question and what is its purpose? Be sure to include the 3 characteristics. That makes it up.

Answer- and statistical question is a question that guides research by defining the population of a given topic and that anticipates variability in the collected data. The purpose of a statistical question is it is the first step of the statistical process. The 3 characteristics of a statistical question are allows for clear responses, includes a specific population, and anticipates variability of the data.

What does it mean for data to have variability as it refers to statistical questions? Give an example.

Example- how many chores do you have? Some people might say 5 or 2 or even 0. It just depends on the person's family.

Well a dot diagram is like this for example,

And a histogram is this,

Dot diagram uses dots and the histogram uses bars.

When would we use them? Well that I can explain, you can use the dot diagram to see what pets people have or even to see how many people scored how many points.

A histogram can be used for a concert. There would be like on the bottom, 0-6, 7-12, and so on. The bars show how many people from what age group are joining the concert.

Explain the difference between center and shape of a data set.

The center is the median and/ or mean of the data. The spread is the range of the data. And, the shape describes the type of graph.

hope this helps give brainiest.

A rectangle has a heigh if 4x^3 and a width of x^3+3x^2+2x

Andrews [41]

Answer:

Area = $4x^6+12x^5+8x^4$

Step-by-step explanation:

The Complete Question:

A rectangle has height $4x^3$ and width $x^3+3x^2+2x$ . What is the area of the rectangle in terms of x?

Solution:

The formula for the area of a rectangle is:

Area = Height * Width

Both the expressions for height and width is given, so we just need to multiply both the expressions to get an expression, in x, for the area of the rectangle. The algebra is shown below:

$A=(4x^3)(x^3+3x^2+2x)\\A=4x^6+12x^5+8x^4$

This is the area of the rectangle.

Answer:

Option C is the correct option.

Solution,

 $3y = 66$ 

(opposite angles of parallelogram are equal )

 $or \: 3 \times y = 66 \\ or \: y = \frac{66}{3} \\ y = 22$ 

hope this helps...

Good luck on your assignment..
