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:
96 square units
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
- The length of the large rectangle is: 5
- The width of the large rectangle is: 7
=> Area of the large rectangle = length × width = 7*5 = 35 square units
- The length of the middle rectangle is: 7
- The width of the middle rectangle is: 4
=> Area of the middle rectangle = length × width = 7*4 = 28 square units
- The length of the small rectangle is: 7
- The width of the small rectangle is: 3
=> Area of the small rectangle = length × width = 7*3 = 21 square units
Area of top and the bottom triangles =2*
Total surface area = 35 + 28 + 21 + 12 = 96 square units
