<span>Probability of an event =(Number of favorable outcomes)/(Total number of outcomes)
Here, the number of favorable outcomes is the number of times 3 comes up.
The number of times 3 comes up = 67
Total number of outcomes is the number of times the cube is rolled.
Total number of times the cube is rolled = 450
Therefore, Probability of getting a 3 =67/450
Since 67 is a prime number, 67/450 is the final answer in simplest form.</span>
Answer:
a) The average of compy heights is 33.5 cm
b) The 68.3 % of all compy heights are in the interval:
(30.94,36.06)
Step-by-step explanation:
a) Meaning of the mean
The mean is a number expressing the central or typical value in a set of data.
The average of compy heights is 33.5 cm. If the select one height randomly its height will be in average 33.5 cm
b) Meaning of standard deviation
The standard deviation is a quantity expressing by how much the members of a group differ from the mean value for the group.
The 68.3 % of all compy heights are in the interval
(33.5cm - 2.56cm, 33.5cm + 2.56cm) = (30.94,36.06)
It means that the 68.3 % of all data is in the interval:
(μ - δ, μ +δ)
Where: μ is the mean
δ is the standard deviation
The answer is A
since 2x+3(2x)=16
Hence 8x=16
