Answer:
Between 12.614 years and 16.386 years
Step-by-step explanation:
Given that:
Mean age (μ) = 14.5 years, standard deviation (σ) = 4.6 years, number o sample (n) and the confidence interval (c) = 90% = 0,9
α = 1 -c = 1 -0.9 = 0.1
The z score of 
is the same as the z score of 0.45 (0.5 - 0.05). This can be gotten from the probability distribution table. Therefore:
The margin of error (e) = 
= 
The interval = μ ± e = 14.5 ± 1.886 = (12.614 ,16.386)
Answer:
c d
Step-by-step explanation:
A line means divided by
So basically if it was 1/2, then it would be 1 divided by 2.
P. S. 1 divided by 2 is not the answer I'm just explaining what a line is
Well. Check out @GiannaSmart0 For the answer ! Great
Answer:
D: (-6,4), R:(1,6)
Step-by-step explanation:
The domain is asking for how far the line goes across the x-axis.
The range is asking for how far the line goes across the y-axis.
Hope this helped
