Answer:
7. The numbers 14/81 are relatively prime
8. b=3
9. 0.00001
19. 11
Step-by-step explanation:
7. Relatively prime numbers have no common factors. We only have to factor each number and compare
14=2*7
35=5*7
38=2*19
81=9*9
91=7*13
The first two numbers have 7 in common
The second have 2 in common
The third set have no common factors
The fourth set have 7 in common
The numbers 14/81 are relatively prime
8.
9.
10. 100,000,000,000=10*10*...10 as many times as zeroes there are, so
Answer:
Step-by-step explanation:
Mean:
The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is
The formula for the mean of a sample is
Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:
Answer: The graph is shown below
The solution to the system is (x,y) = (2,3)
=============================================================
Explanation:
To graph , we need two points. Generating any (x,y) point involves picking a random x value to find its paired y value. For instance, if you plugged in x = 0, you should get to y = -2 which is the y intercept. Then trying something like x = 2 will lead to y = 3. This line goes through (0,-2) and (2,3). This line is shown in red below.
The blue line is horizontal and goes through 3 on the y axis. Every point on this horizontal line has the same y coordinate of 3. The x value doesn't matter, so it's not part of the equation y = 3.
The intersection of the red and blue line is the solution to the system. That intersection occurs at (x,y) = (2,3). This means x = 2 and y = 3 pair up together to make both original equations true.
Since this system has at least one solution, we consider it a consistent system.
I have drawn the graphs.you can get from them,maybe turn left 2
8/11, I’m assuming it’s 2 times the last item.
