Answer:
The answer is below
Step-by-step explanation:
The mean (μ) = 3.7 m, standard deviation (σ) = 1.17 m, confidence (C) = 95% = 0.95, sample size (n) = 50
a) α = 1 - C = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
The z score of α/2 is the same as the z score of 0.475 (0.5 - 0.025) which is 1.96. Hence:
The margin of error (E) = 
The confidence interval = μ ± E = 3.7 ± 0.32 = (3.38, 4.02)
b) This means that we are 95% sure that any distance between the taxi and the lead car is between 3.38 m and 4.02 m

Step-by-step explanation:
Answer:
111 degrees
Step-by-step explanation:
the total degrees in a hexagon is 720 degrees.
the known angles add up to 379, so there is 341 degrees left.
angle KFE is 105 degrees because it adds up to 180 degrees with GFK.
angle LAD is 130 degrees because it adds up to 180 degrees with BAD.
130+105=230, so there is now 111 degrees left and that is angle x
