Answer:

Step-by-step explanation:

Ok, so we have to help your pupil (lets call her Jane) figure out "why researchers should use a random sample to conduct a survey". So, i will list all of the choices.

A random sample is likely to avoid bias
In a random sample some members of the population are more likely to be selected than others
Random samples provide consistency and systematically favor one choice over every other choice in each survey question
Random sampling will provide a more representative sample of population
Researchers can use a random sample to draw conclusions about the population

Random sampling is used to get the best average, and not favor any one opinion. For example, if you were trying to figure out the daily spending budget of people, you wouldn't just go to the upper clas part with all the rich people, you would survey from all over the town to get results from all kinds of people. So, the answers are:

A random sample is likely to avoid bias (because thats exactly what they do)

Random sampling will provide a more representative sample of population (because they are designed to do that)

Researchers can use a random sample to draw conclusions about the population (thats why they take the samples)

Hope this helps

Michael is trying to write the algebraic expression for the following word phrase: the quotient of 6 and the sum of 5 and y? Mic

gizmo_the_mogwai [7]

Answer:

Error: He multiplied 6 by 5 + y instead of divided 6 by 5 + y

Correct solution: 6 ÷ (5 + y)

Step-by-step explanation:

- Lets revise some words of some operations in mathematics

# The sum ⇒ (+) Add

# The difference ⇒ (-) subtract

# The product ⇒ (×) multiply

# The quotient (answer of division) ⇒ (÷) divide

* Lets solve the problem

- Michael is trying to write the algebraic expression for the following

word phrase:

the quotient of 6 and the sum of 5 and y

- Lets explain that: the quotient means the answer of division so he

wants to divide a quantity by another one

∵ The first quantity is 6

∵ The second quantity is the sum of 5 and y

- He wants to divide 6 by (5 + y)

∴ The expression is 6 ÷ (5 + y)

* Error: He multiplied 6 by 5 + y instead of divided 6 by 5 + y

* Correct solution: 6 ÷ (5 + y)
