Step 1: arrange the data points in order
12 14 24 30 35 40 42 50 53 Step 2 : Find the median.
median is 35. Step 3. divide the data points into two : left and right
of median
12 14 24 30 and 40 42 50 53
Step 4: find median of each12 14 24 30 : (14+24)/2 = 1940 42 50 53 : (42+50)/2 = 46
step 5. draw lines on the scale on the median, two other
medians and least and the greatest value

Answer: The correct option is
(D) The sequence is not arithmetic because the terms do not have a common difference.
Step-by-step explanation: We are given to select the true statement regarding the sequence that is graphed in the figure.
From the graph, we see that some of the points are (1, 1), (2, 4), (3, 9), (4, 16), (5, 25).
That is, if we write the graphed points in terms of a sequence <a(n)>, then we get

The sequence <a(n)> will be arithmetic if the difference between the consecutive terms is equal. That is, the terms should have a common difference.
Now,

This implies that the terms do not have a common difference and so the graphed function does not represent an arithmetic sequence.
Thus, the sequence is not arithmetic because the terms do not have a common difference.
Option (D) is CORRECT.
Answer:
Option B) 0.2143
Step-by-step explanation:
We are given the following in the question:
Numbers of exposures(x): 4,3,7
We have to find the maximum likelihood estimate of p.
Formula:

Putting the values, we get,

Thus, the correct answer is
Option B) 0.2143
