Richard is 6 years older than Lisa and in 5 years the sum of their ages will be twice as much as the sum of their ages 4 years ago. Find their present ages.?
Let Lisa's current age be ( x ). Then Richard's age is ( x + 6 ). In 5 years, their ages will be ( x + 5 ) and ( x + 11 ), respectively. The equation for their ages in 5 years is ( (x + 5) + (x + 11) = 2[(x - 4) + (x + 2)] ). Simplifying this gives ( 2x + 16 = 2(2x - 2) ), leading to ( 2x + 16 = 4x - 4 ). Solving for ( x ), we find ( x = 10 ) (Lisa's age) and ( x + 6 = 16 ) (Richard's age). Thus, Lisa is 10 years old and Richard is 16 years old.

A hypothetical population consists of eight individuals ages 13 16 19 23 24 27 29 and 30 years. (Enter your answers to three decimal places.)?
To analyze the hypothetical population with ages 13, 16, 19, 23, 24, 27, 29, and 30, we can calculate the mean and standard deviation. The mean age is calculated as the sum of all ages divided by the number of individuals, which gives a mean of 23.125 years. The standard deviation, which measures the dispersion of ages around the mean, is approximately 5.139 years.
