<span>set x = length, then x-14 would be width,
perimeter would be 2(x) + 2(x-14) = 96,
simplify this, u get 2x + 2x - 28 = 96,
you then get 4x = 124, now we know x = 31,
you would then be 31-14 which is 17.
so length is 31 m and width is 17 m</span>

Answer:
Confidence interval for the mean consumption of milk per week among males over age 25 in 85% confidence level is (2.8≤μ≤3.0)
Step-by-step explanation:
Consumption of milk among males over age 25 can be found using the formula:
M± where M is the <em>sample mean</em>, z is the corresponding <em>z-score for 85% confidence level</em>, s is the <em>population standard deviation</em>, N is the <em>sample size</em>.
In this sample, mean of milk consumption per week among males over age 25 is 2.9 liters. Corresponding z-score for 85% confidence interval is 1.440. standard deviation of the sample is 1.1. And sample size is 513. When we put these numbers in the formula, we got:
2.9± =2.9±0.07
