ANSWER:}------> <u><em>line b</em></u>
Answer
Find out the The numerical value of A - B and the numerical value of B - A .
To prove
As given
The expression 113.47 - (43.72 - 26.9) represents A.
The expression 113.47 - (26.9 - 43.72) represents B .
Thus
A - B = 113.47 - (43.72 - 26.9) - ( 113.47 - (26.9 - 43.72))
First solving the bracket terms.
A - B = 113.47 - (43.72 - 26.9) - 113.47 + (26.9 - 43.72)
= 113.47 - 16.82 - 113.47 - 16.82
= 113.47 - 113.47 - 16.82 - 16.82
= -33.64
Therefore the value of A- B is -33.64 .
Thus
B - A = 113.47 - (26.9 - 43.72) - (113.47 - (43.72 - 26.9))
First solving the bracket terms.
B - A = 113.47 - (26.9 - 43.72) - 113.47 + (43.72 - 26.9)
= 113.47 + 16.82 - 113.47 + 16.82
= 33.64
Therefore the value of the A - B is -33.64 and B - A is 33.64 .
Answer: A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
Step-by-step explanation:
Here are the options:
A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
B) A boy is 33% more likely than a girl to own a dog than a cat or other animal.
C) A boy is 50% more likely than a girl to own a dog than a cat or other animal.
D) A boy is 52% more likely than a girl to own a dog than a cat or other animal.
Boy with a dog = 27
Total animals owned by boys = 27+15+10 = 52
Probability of owning a dog = 27/52 = 0.5192
Girl with dogs = 18
Total animals owned by girls = 18+25+12 = 55
Probability of owning a dog = 18/55 = 0.3273
Therefore, 0.5192 - 0.3273 = 0.1919 = 19.19%
Therefore, A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
