Answer:

No, because a random sample from all customers of the shopping mall was not selected.

Step-by-step explanation:

In taking a survey, it's quiet obvious that everybody cannot be reached and the opinion of all cannot also be heard. That is why a good survey is taken at random and not from one set of individual. Therefore, the results of the survey can't be generalized.

Answer:

No. The results of the survey cannot be generalized to the population of all customers of the shopping mall.

Step-by-step explanation:

Survey results are biased, because data is collected from customers who came trough one specific door of the mall.

Some of the customers <em>may be using some other door </em>where satisfaction survey is not given to these people while passing the door.

Therefore survey results does not reflect thoughts of the population of all customers.

What is the product and simplest form 2/3 times 1/8
ludmilkaskok [199]

Answer:

\frac{1}{12}

Step-by-step explanation:

Since we're finding the product, we have to multiply:

\frac{2}{3} × \frac{1}{8}

You can simplify in this stage by using the "butterfly method", and dividing 2 by 2, and 8 by 2, you'd then have:

\frac{1}{3} × \frac{1}{4}

Multiply the numerators and the denominators to get:

\frac{1}{12}

~

If you prefer the longer way, again, multiply:

\frac{2}{3} × \frac{1}{8}

Multiply the numerators and the denominators:

\frac{2}{24}

Simplify the fraction by dividing both the numerator and denominator by 2:

\frac{1}{12}
