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.

Answer:
Refer to the picture above
Answer:
4
Step-by-step explanation:
12.56/3.14=4 which you the square root to get 2. The add 2+2 to get your diameter of 4.
2 5/6 = 17.6 - hope it help
The hyperbola is more or less as in the picture below
notice the traverse axis is horizontal, meaning the positive fraction will be the one with the "x" variable in it, and notice the length of the "a" component
the conjugate axis is 10, notice the length of the "b" component
thus
so, hmmmm plug in those values
