Let's call :
x=the number of downloaded standard version
y= the number of downloaded high-quality version
We have : -the high-quality version was downloaded three times as often as the
standard version => 3x=y
-standard version is 2.8 megabytes .the high-quality version is 4.6
MB.The total size downloaded for the two versions was 4482 MB
=> 2.8x+4.6y=4482
Solve for x,y
x=270 , y=810
Answer:
Option B.
Step-by-step explanation:
From the given venn diagram it is clear that
Since the intersection of A and B is non-empty, therefore by conditional probability
Therefore, the correct option is B.
Answer:
Step-by-step explanation: There are many ways to think about slope. The slope of a line is the steepness of the line. It can be also right Slope is the rise over the run, the change in 'y' over the change in 'x', or the gradient of a line
