Answer:
[0,50]
Step-by-step explanation:
The function takes from value the distance from the plane to the building, and returns the height of the plane at that point in feets. Assuming that the plane goes always down, it will always be up to the height of the building. Note that the horizontal distance the plane travels at any point is equivalent to the distance of the plane with the building at that point, because the building is perpendicular to the ground. So, at the end of the travel the plane will be 50 feets away from the building. SInce it starts at 0 distance, then the domain of the function is [0,50]
The Goldbach Conjecture is a yet unproven conjecture stating that every even integer greater than two is thesum of two prime numbers. The conjecture has been tested up to 400,000,000,000,000. Goldbach's conjecture is one of the oldest unsolved problems in number theory and in all of mathematics.
Answer:
D. 31
Step-by-step explanation:
To find the mean of any group of numbers, you simply add up all the numbers and then divide by how many numbers there are.
Using a calculator or a pencil, add the following:
27 + 28 + 30 +28 + 28 + 31 + 29 + 33 + 28 + 28 + 31 + 33 + 41 + 41 + 25
= 461
The last step is to divide 461 by 15:
461/15 = 30.73
Round 30.73 to the nearest whole number and you get D. 31
