The answer is A. Because if you subtract 3 from 23 it will be 20 and 20 divided by 2 is 10
actually write it down if not i can not help you!!!
That would be 5.979 x 10 to the power of 7.
Easy way to work that out is you put the decimal point after the first number and then count all the spaces after and thats the power it's to!
Given scatter plot contains Hours spent on playing online games on X-axis and scores obtained on test along with Y-axis.
If we observe the data points then there is decrease in test scores and number of hours spent on playing online games increases.
Let use see first few data point (0.1, 99), (0.5, 97), (0.7, 89), (1.5, 85), (2, 75), (2.5, 70), (2.75, 78) then we can see that for first two pairs the number of hours spent on playing online games increases from 0.1 to 0.5 the test scores decreases from 99 to 97. Also the same relationship is observed if we pick any two data points from given data set.
So the number of hours they play games online increases -
Test scores will decrease because the graph shows a negative association
