1 answer:
Answer:
0.394
Step-by-step explanation:
Given:
Percent of 3 year-olds enrolled in daycare = 39.4%
The above statement means that if the total number of 3 year-olds is 100, then out of the 100 persons aged 3 years, the number of persons enrolled in a daycare is 39.4.
Now, probability of an event is the ratio of the favourable outcomes for that event to the total number of outcomes.
Here, the favourable number of outcomes is the number of persons aged 3 years enrolled in a daycare which is equal to 39.4.
The total number of outcomes is the total number of 3 year-olds which is 100.
Therefore, the probability that a randomly selected 3-year-old is enrolled in daycare is given as:

Answer: 32
But say we didn't know the formula. We can chop out the 4 by 4 square and we have two 45/45/90 triangles side 4 left over, so two 4 by 4 squares,
A = 2(4)(4) = 32
We can think of this as 12 by 4 rectangle with two 4 by 4 right triangles chopped out:
A = 12(4) - 2(1/2)(4)(4) = 48 - 16 = 32
