We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
Answer:
E
Step-by-step explanation:
5x+3y+6x+9y
All you'd need to do is combine like terms. So add 5x to 6x and add 3y to 9y.
(5x+6x)+(3y+9y)
Final Answer: 11x + 12y
Answer:
The diameter is 47
Step-by-step explanation:
Given
--- Circumference
Required
Determine the diameter (d)
The circumference of a circle is:
Make d the subject
13-11 = 2
15-13 = 2
17-15 = 2
As you can see, the numbers increased by two. hence the answer is 2.
