He simultaneous equations<br>5x + y = 21<br>x - 3y = 9 <br><br>With working out

Elza [17]

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

5x + y = 21 → (1)

x - 3y = 9 → (2)

Multiply (1) by 3 and add the result to (2) to eliminate y term

15x + 3y = 63 → (3)

Add (2) and (3) term by term

(x + 15x) + )- 3y + 3y) = (9 + 63)

16x = 72 ( divide both sides by 16 )

x = 4.5

Substitute x = 4.5 into (1) for corresponding value of y

22.5 + y = 21 ( subtract 22.5 from both sides )

y = - 1.5

Solution is (4.5, - 1.5 )

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.
