Answer:
15.85%
Step-by-step explanation:
Empirical rule states that for a normal distribution, 68% of the data falls within one standard deviation, 95% falls within two standard deviation and 99.7% falls within three standard deviation.
Given mean (μ) = 41 months, standard deviation (σ) = 5 months
One standard deviation = μ ± σ = 41 ± 5 = (36, 46)
Therefore 68% falls within 36 months and 41 months
Two standard deviation = μ ± 2σ = 41 ± 2(5) = (31,51)
Therefore 95% falls within 31 months and 51 months
Three standard deviation = μ ± 3σ = 41 ± 3(5) = (26, 56)
Therefore 99.7% falls within 26 months and 56 months
The percentage of cars that remain in service between 46 and 51 months = 32%/2 - 0.3%/2 = 16% - 0.15% = 15.85%
Answer:
(m + 7)^2
Step-by-step explanation:
The SQUARE of (The SUM of m and 7)
Let us try (The SUM of m and 7) first
(m + 7)
then try the square
(m + 7)^2
Answer:
6a-24=6a-24
Step-by-step explanation:
you distribute the 2 on the first equation (2(3a-12)) so 2 times 3a is 6a and -12 times 2 equals -24 so the simple form for the first equation is 6a-24. You do the same for the second equation 3 times 2a is 6a and 3 times -8 is -24. So the equations are the same on each side meaning they have infinite solutions on a graph.
