If the results of the survey were claimed to indicate that 7.7% of adults in the country who own digital cameras plan to replace their camera in the next 12 months would you say is this statement is descriptive or inferential

The above statement is inferential in its approach.

Step-by-step explanation:

Inferential results are deferred results meaning results are deduced from the above assumptions or survey.  

As per the results of the survey, 7.7% of adults in the country owning a digital camera and are in process to replace their camera in the coming 12 months.

This means that the survey formed the basis of the above-made deduction that of all the 7.7% adult who owns a camera is planning to replace it. Hence the statement is inferential in its approach.

16

Step-by-step explanation:

We must find integers x, y with the most amount of prime divisors, not necessarily distinct, such that x + 3y < 1,000.

Obviously, this is achieved when the divisor is the least prime 2. So, we must find integers n, m such that

since , then n must be 9. For n=9 we find the greatest integer m such that  

and we find m=7

 and   ,  are the numbers we are looking for and the sum of their length is 9+7 = 16.

So, 16 is the maximum possible sum of the length of x and the length of y.
