So, we have:
The slope m is calculated as:
Answer:
1. C)
2. D)
Step-by-step explanation:
We know that:
1/3 is afraid of spiders
1/12 fears spiders and snakes
Then, the proportion of children who fear spiders and also snakes is calculated as:
Option C)
Of the 1/3 of children who fear spiders, 1/4 of them also fear snakes.
Now:
1/2 is afraid of the serientes
1/12 fears spiders and snakes
Then, the proportion of children who fear spiders and also snakes is calculated as:
Option D)
Of the 1/2 of children who fear snakes, 1/6 of them also fear spiders
The answer is D.4/63. This is because you have to start by multiplying to get the denominators to be the same. in this case, we multiply by 9 and 7 to get 63. Then, what we did to the top must be done to the bottom, so we multiply to end up with 18/63 and 14/63.
