Domain of a set of ordered pairs
We know the domain is the set of all x when is represented by ordered pairs: (x, y)
In this case {(-8,-12),(4,-8), (2, -10),(-10.-16) } we can observe that there are four x (the first number of each pair):
Domain = { -8, 4, 2, -10}
<h2>Domain = {-10, -8, 2, 4}</h2>
25X100= 2,500 at the door
2,500-20,500 = 18,000 lift
18,000/15 =1,200 people on line
Step-by-step explanation:
the patern (3n - 1) is incorrect,
the correct pattern should be
Tn = n² + 1
Correct answer is 0.2
0.2 * 0.2 is 0.04
then 0.04 * 0.2 = 0.008
Using the Empirical Rule, it is found that the lifespans, in months, are given by:
1. 24 and 32.
2. 20 and 36.
3. 16 and 40.
<h3>What is the Empirical Rule?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Hence, considering the mean of 28 months and the standard deviation of 4 months, the life spans are given by:
1. 24 and 32.
2. 20 and 36.
3. 16 and 40.
