Answer:
Step-by-step explanation:
Let x be a random variable representing the life of a Brand Q car battery. With the mean and standard deviation given, then the Empirical Rule says the that
1) About 68% of the x values lie between 1 standard deviation below and above the mean.
2) About 95% of the x values lie between 2 standard deviations below and above the mean.
3) About 99.7% of the x values lie between 3 standard deviations below and above the mean.
From the information given,
mean = 36 months
Standard deviation = 4 months
Therefore,
1) 68% of all batteries will have a life between 36 - 4 = 32 months and 36 + 4 = 40 months.
2) 95% of all batteries will have a life between 36 - 2(4) = 28 months and 36 + 2(4) = 44 months.
Answer:
"a particular order in which related events, movements, or things follow each other." (google dictionary)
Step-by-step explanation:
Answer:
It is correct because the smallest one is 3 the second one all together is 15 and the last one is 60.
Step-by-step explanation: Basically you can divide the 60 with 15 and you can divide 60 with 3.
60/15 = 4
60/3 = 20
and 4 can go in to 20 5 times so yeah.
And I hope I helped you out.
It means that the two vectors are perpendicular or orthogonal
