Answer:

Yes, it will be a biased study.

Step-by-step explanation:

Given is that -

Pollsters take a survey of people at a ball game to collect and analyze data about favorite leisure activities of star city’s residents.

This study will be biased and it will produce biased results.

Firstly, few people at ball game do not represent the whole population of the city and it is not necessary that all the people at ball park will respond to the question in the survey.

Factor the expression using the GCF. A. 2(4a + 8c) B. 4(2a + 4c) C. 8(a + 2c) D. 16( 12 a + c) Not multiple choice
dimulka [17.4K]

Note: The expression is missing. Consider the expression is 8a+16c.

Given:

The expression is

8a+16c

To find:

Factor form of the given expression by using GCF.

Solution:

We have,

8a+16c

Factors of each term:

8a=2\times 2\times 2\times a

16c=2\times 2\times 2\times 2\times c

The common factors are 2, 2 and 2. So,

GCF(8a+16c)=2\times 2\times 2

GCF(8a+16c)=8

Taking out the greater common factor (GCF) in the given expression, we get

8a+16c=8(a+2c)

Therefore, the required expression is 8(a+2c) and the correct option is C.
