Answer:
34%
Step-by-step explanation:
Given that the distribution of daily light bulb request replacement is approximately bell shaped with ;
Mean , μ = 45 ; standard deviation, σ = 3
Using the empirical formula where ;
68% of the distribution is within 1 standard deviation from the mean ;
95% of the distribution is within 2 standard deviation from the mean
Lightbulb replacement numbering between ;
42 and 45
Number of standard deviations from the mean /
Z = (x - μ) / σ
(x - μ) / σ < Z < (x - μ) / σ
(42 - 45) / 3 = -1
This lies between - 1 standard deviation a d the mean :
Hence, the approximate percentage is : 68% / 2 = 34%
Hi!
So, 32/4=8. Each side is 8 feet long, with a square area of 64 ft^2. If you devide 32/3, that's 10.6 feet you painted. That aside, it's not what the question asks.
If you painted 1/3, and there are four sides, 12 can be used as it is the lcm (least common multiple). 4/12 can be used here, I believe.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
Answer:
Step-by-step explanation:
Cost (C) depends on the number of miles traveled (x).
So C is the dependent variable.
Or C(x) if they want you to be more specific.
x is your independent variable.
Miles driven do not depend on anything.
Well i remember doing this awhile back but your not giving very much detail but i think it’s c if I’m wrong just correct me
