Answer:
The correct option is A.
Step-by-step explanation:
From the given scatter plot in is clear that the coordinate pairs of points are (1,1.5), (2,2), (3,3), (4,4), (5,6), (6,6.5), (7,7), (8,8), (9,9), (10,10).
If a line best represents the data, then that line is called line of best fit. The line may or may not passes through all the points.
The main objective of this method is to minimizes the squared distance of each point from the line of best fit.
Draw a line of best fit as shown below.
From the graph it is clear that the line of best fit passes thorugh the points (0,0.5) and (10,10).
Therefore the correct option is A.

Answer:
Step-by-step explanation:
The sum is larger than 9, it means we have: 10, 11, and 12
- To get the outcome is 12, we have only one way is that the two dice shows face-6. The probability to have 12 is:
P(12) = =
- To get 11, we have it two ways once dice shows face-5 and the other shows face-6 and vice versa
P(11) = 2* =
- To get 10, we have it three ways ( once dice shows face-5 and the other shows face-6 and vice versa , two dice show 5)
P(10) = 3* =
So the probability of getting a number larger than 9 for the first time on the third roll is:
P(12) + P(11) +P(10 )
= +

=
Answer:
Step-by-step explanation:
Let's look at the numbers that we count.
The question says not multiple of 2, so we have to count to following numbers:
1 , 3 , 5
And in total there are 6 numbers, so our probability is
=
Answer:
The probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
Step-by-step explanation:
We are given that
n=4
We have to find the probability that the average score of a group of n = 4 people is between 70 and 75.
Hence, the probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
