Hello from MrBillDoesMath!
Answer:
d>4
Discussion:
I understand the question is asking us to solve for "d" in the inequality:
d + 2 > 6 => subtract 2 from both sides
d + 2 -2 > 6 - 2 => as 2 - 2 = 0
d > 6 -2 = 4
If I have misunderstood the question, please tell me.
Thank you,
MrB
Answer:
Where the mean and the deviation
Since the distribution for X is normal then we can conclude that the distribution for the sample mean is given by:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where the mean and the deviation
Since the distribution for X is normal then we can conclude that the distribution for the sample mean is given by:
Answer:
P(6) = 5
Step-by-step explanation:
The dice is cast 30 times (k = 30)
So if the big numbers apply, then you would expect the outcome to be evenly distributed, meaning
5 x 1
5 x 2
5 x 3
5 x 4
5 x 5
5 x 6
____ +
30 casts in total (evenly distributed over all numbers of the dice)
P(6) = 1/6 * 30
P(6) = 5
