Answer:
At least 68% of observations lie between 22 and 26 months.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 24
Standard deviation = 2
22 = 24 - 2
22 is one standard deviation below the mean
26 = 24 + 2
26 is one standard deviation above the mean.
So, by the empirical rule, at least 68% of observations lie between 22 and 26 months.

To add decimals, line up the decimal points.
Here are some examples.
1.2
1.43
10.2
2.5
938.290
21.001
After you line up the decimal points, just add and carry down the decimal point.
14.37
5.63
_____
20.00
So, the answer is 20.
Answer with explanation:
- An algebraic expression having one term is known as a monomial.
- An algebraic expression having two terms is known as binomial.
- An algebraic expression having three terms is known as trinomial.
- Numerical coefficient - Number written before variable in each term.
- Constant - term with no variable ( only number).
Let's check the given expressions :
Type - Monomial ( having one term)
Coefficient of 
= 3
Constant =0
Type - Monomial ( having one term)
Coefficient of 
= 5
Constant =0
Type - trinomial ( having 3 terms)
Coefficient of = 2
Coefficient of 
Constant = -8
