Get all the n together so 3n+2n=5n
5n-17=38
Minus 17 from both sides
5n= 55
N= 11
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.
Answer:
minimum = $445
median = $565
standard deviation = $38
IQR = $48
Step-by-step explanation:
The minimum and the median are measures of location and are affected during addition (or subtraction) and multiplication (or division).
Satandard deviation and IQR (inter-quartile range), which are measures of dispersion, are affected by only multiplication (or division).
For the weight,
<em>minimum </em>= 920 pounds
<em>median </em>= 1160 pounds
<em>standard deviation</em> = 76 pounds
<em>IQR </em>= 96 pounds
For the price,
<em>minimum </em>= 0.50(920) - 15 = $445
<em>median </em>= 0.50(1160) - 15 = $565
<em>standard deviation</em> = 0.50(76) = $38............(<em>Subtraction discarded</em>)
<em>IQR </em>= 0.50(96) = $48........................................(<em>Subtraction discarded</em>)
