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:
This is the answer.
Step by step explanation :
Answer:
2n
Step-by-step explanation:
2n = 2*n
36n = 2*3*2*3 n
They both have 2*n in common, so the greatest common factor is 2n
Okay this is the basic when there is a - + + = -
Answer:
The mean is 0.32 and the standard deviation is 0.0122.
Step-by-step explanation:
Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.
Of the respondents, 48% said they put their shirt on first.
32% of all adults actually put their shirt on first
i.e. sample proportion is 48% while population proportion is 32%
Hence sampling distribution follows a distribution with mean = population proportion p
Hence here mean = 0.32
Std deviation of sampling distribution = 
Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.
is right
