Answer:
C. 53%
Step-by-step explanation:
From the table, we see that,
The number of families in Survey 1, 3 and 4 are increasing as the number of pets increases.
But, that is not happening in Survey 2. This might be due to some bias.
<em>Thus, Survey 2 is most likely to be biased.</em>
So, we get the unbiased survey are 1, 3 and 4.
So, the number of families in these surveys having 2 or more pets are,
Survey 1 = 25, Survey 3 = 27, Survey 4 = 27
So, the total number of families having 2 or more pets = 25 + 27 + 27 = 79
Also, the total number of families for the 3 surveys = 50 + 50 + 50 = 150
Thus, the percent of families having 2 or more pets = = 52.7% ≈ 53%
Hence, option C is correct.

Answer:
80km
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (1.2, 1.0, 96) as shown below:
Next we cross multiply. We multiply 1.2 and x, and we multiply 96 and 1.0.
1.2(x) = 1.2x
96 x 1.0 = 96
Now, lets put the values above back into the equation:
1.2x = 96
Lets solve this equation. First we divide 96 by 1.2.
1.
2.
This means that our answer is 80km.
Answer:
The eighth of an inch scale measures more precisely.
Step-by-step explanation:
An eighth of an inch means that one inch is divided into 8 equal lengths on the scale i.e. the minimum length that can be measured is inch.
Again a fourth of an inch means that one inch is divided into 4 equal lengths on the scale i.e. the minimum length that can be measured is inch.
Therefore, the eighth of an inch scale measures more precisely as it can measure more small measurements. (Answer)
