Using a calculator, inserting the values of x and y, the correlation coefficient for the given data-set is of -0.9422.
<h3>How to find the correlation coefficient of a data-set?</h3>
Using a calculator, the correlation coefficient is found inserting the ordered pairs (x,y) in the calculator.
In this problem, we have that:
- The values of x are: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
- The values of y are: 112.5, 110.875, 106.8, 100.275, 91.3, 79.875, 70.083, 59.83, 30.65, 0.
Hence, using a calculator, the correlation coefficient is of -0.9422.

Answer:
The median of the data set is 11.
Step-by-step explanation:
2, 2, 5, 10, 12, 13, 18, 24
10 + 12 = 22
22 / 2 = 11
Times them all :) and that's your answer
if there are 9 small boxes that contains 10 pens in each box that is a total of 90 pens. 2 large boxes which has 15 pens in each box that is a total of 30 pens. so all together you have 120 prizes. you need 200 so you subtract 120 from 200 which leaves you needing 80 prizes. your answer is 80 more prizes.
