Answer:
One of these
Step-by-step explanation:
No. For it to be in standard form the term with the largest exponent comes first. Standard form would be 6x^2-3x. It is a second degree polynomial because 6x is raised to the 2nd power. It would be a third degree polynomial if the largest degree was raised to the 3rd power.
The answer is B. Testing random samples of wild animals to decide whether they are healthy
Let x be number of downloads of standard version and y be number of downloads of high quality versions.
The hight quality downloads are twice as the standar downloads. So,

The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,

Substitute 2x for y in the equation and solve the obtained equation for x.

So value of x is 290. Thus downloads of the standard version were 290.
Answer: 290
