Answer:
Down below
Step-by-step explanation:
P = 2L + 2W
P = 108
L = 2W+12
108 = 2(2W+12) + 2W
108 = 4W + 24 + 2W
108 = 6W + 24
84 = 6W
14 = W
W = 14
If the width is 14, then the length is twice that plus 12, or 38
38 + 38 + 14 + 14 = 108

Answer:
99% confidence interval for the mean value from the random number generator is a lower limit of 85.87 and an upper limit of 110.93.
Step-by-step explanation:
Confidence interval = mean +/- margin of error (E)
mean = 98.4
sd = 16.3
n = 15
degree of freedom (df) = n - 1 = 15 - 1 = 14
confidence level (C) = 99% = 0.99
significance level = 1 - C = 1 - 0.99 = 0.01 = 1%
t-value corresponding to 14 df and 1% significance level is 2.977.
E = t×sd/√n = 2.977×16.3/√15 = 12.53
Lower limit = mean - E = 98.4 - 12.53 = 85.87
Upper limit = mean + E = 98.4 + 12.53 = 110.93
99% confidence interval for the mean is between 85.87 and 110.93
