Write an expression to convert kilogram to grams. Let K stand for kilograms.
Kay [80]

Answer:

g = 1000K

Formula: Multiply the amount of kilograms with 1000 to convert it into grams

Step-by-step explanation:

Kilo stands for 10³ or 1000. So, a kilogram means one thousand grams. This means that if you ever want to get back to grams from kilograms, all you need to do is multiply the number of kilograms by 1,000.

Number of grams = Number of kilograms x 1000

g = 1000K

san4es73 [151]

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.
