What is the median of 20.3 12.5 7.6 13.9 9.2 21.7 17.5 15.6 14.1

14.1

Step-by-step explanation:

We have been given a data set. We are asked to find the median of our given data set.

First of all, we will arrange data points in ascending order.

7.6, 9.2, 12.5, 13.9, 14.1, 15.6, 17.5, 20.3, 21.7

We can see that our given data set has 9 data points. The median of the given data set will be middle value that is value of 5th data point.

We can see that 5th data point of our given set is 14.1, therefore, the median of the given data set is 14.1.

answer: 45

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
