An operation that is done to a value and it stays the same, it is called the "identity property".

Some quick examples:

Adding any number with zero will result in the same number.

Multiplying any number with one will result in the same number.

Hope this helps!

Which equation represents the graphed function?

nadezda [96]

9514 1404 393

Answer:

y = 1/4x -2

Step-by-step explanation:

The line rises one unit from -2 to -1 as x changes from 0 to 4. The slope is ...

m = rise/run = 1/4

The y-intercept (b) is where the line crosses the y-axis, at y = -2.

The equation in slope-intercept form is ...

y = mx + b

y = 1/4x -2

Complete parts (a) and (b) using the probability distribution below.

katen-ka-za [31]

Μ = (0×0.026) + (1×0.072) +(2×0.152) + (3×0.303) + (4×0.215) + (5×0.164) + (6×0.066)
μ = 0 + 0.072 + 0.304 + 0.909 + 0.86 + 0.82 + 0.396
μ = 3.361 ≈ 3.4

We need the value of ∑X² to work out the variance
∑X² = (0²×0.026) + (1²×0.072) + (2²×0.152) + (3²×0.303) + (4²×0.215) + (5²×0.164) + (6²×0.066)
∑X² = 0+0.072+0.608+2.727+3.44+4.1+2.376
∑X² = 13.323

Variance = ∑X² - μ²
Variance = 13.323 - (3.4)² = 1.763 ≈ 2

Standard Deviation = √Variance = √1.8 = 1.3416... ≈ 1.4

The correct answer related to the value of mean and standard deviation is the option D

An employee works an average of 3.4 overtime hours per week with a standard deviation of approximately 1.4 hours.

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

sattari [20]

Answer:

Step-by-step explanation:

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.

A statistical question has more than one possible answer

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.
