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%
44.120,44.102,44.012 because they are all 44 and look at the number next to 44 it's 0 1 1 and the ones are bigger and the first Bremer the the least move to the second number 0 2, 2 is bigger than 0 so, 44.120 is the biggest
X = 180 - (90 + 47)
x = 180 - 137
x = 43
answer angle x = 43
Answer:
Yes
Step-by-step explanation:
you can plug any number from the graph on the line and it's still going to equal something, i'm sorry this is really bad explaing but when it's a straight line you can plug anything in and still get an answer
