ssors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
The results do not represent the population because not all college professors actually responded.

The results do not represent the population because the sample does not represent professors from different areas.

Answer:

The results do not represent the population because the sample does not represent professors from different areas.

Step-by-step explanation:

Given that Traverion wants to find the answer to the question “How much money does the average college professor make?” He surveys 50 professors from the university in his hometown.

Just because he surveyed 50 professors from the same area the university in his home town, this sample from one area cannot represent the entire population of professors living in different areas

Hence Option 2 is right answer.

Answer: The results do not represent the population because the sample does not represent professors from different areas.


Step-by-step explanation:

Since Traverion wants to find the answer to the question “How much money does the average college professor make?”

He only surveys 50 professors from the university in his hometown.

Although he should survey professors from different areas but he only perform his survey only a specific university in his hometown.

Therefore, the survey is biased as the sample size is too small.

Hence, The results do not represent the population because the sample does not represent professors from different areas.

A device produces random 64-bit integers at a rate of one billion per second. After how many years of running is it unavoidable
nikitadnepr [17]

Answer:

3171 × 10^(44) years

Step-by-step explanation:

For each bit, since we are looking how many years of running it is unavoidable that the device produces an output for the second time, the possible integers are from 0 to 9. This is 10 possible integers for each bit.

Thus, total number of possible 64 bit integers = 10^(64) integers

Now, we are told that the device produces random integers at a rate of one billion per second (10^(9) billion per second)

Let's calculate how many it can produce in a year.

1 year = 365 × 24 × 60 × 60 seconds = 31,536,000 seconds

Thus, per year it will produce;

(10^(9) billion per second) × 31,536,000 seconds = 3.1536 × 10^(16)

Thus;

Number of years of running is it unavoidable that the device produces an output for the second time is;

(10^(64))/(3.1536 × 10^(16)) = 3171 × 10^(44) years

One linear expression is subtractive from a second linear expression and the difference is X -5 what is the difference when the
lesya692 [45]
For this case, the first thing we must do is identify the linear expressions.
 first linear expression = y1 = x
 second linear expression = y2 = 5
 We have then that the difference of the second with respect to the first is:
 y2-y1 = 5-x
 Answer:
 
The difference when the second line is here is subtracted from the first is:

35. How much leather is needed to sew a ball
just olya [345]

Answer:

593.04 square inches leather is needed.

Step-by-step explanation:

Leather needed to sew a ball = Surface area of the ball

Surface area of the sphere = 4πr²

                                             = 4π(6.55)²

                                             = 539.13 inches²

Since 10% extra material is needed for the seams, amount of material required = 539.13 + (10% of 539.13)

= 593.043

= 593.04 square inches

593.04 square inches of leather will be needed.
