Part A: the x-cordinates of where the graphs of the equations intercept are solutions because they make each side of the equation equal to the same value, making them equal. Basically, both functions put out the same value at that point x, making them equal.
Part B: See the attached image. From the tables we can see that both equations have the same output at x=-2, so that is where the graphs would intersect and that would be the solution. They both put out .0625 at x=-2
Part C: You can solve the equation 4^x=2^(x-2) graphically by plotting both sides of the equation as separate functions. In your graphing calculator, you would plot y=4^x and y=2^(x-2), and see at what x-value they intersect to find the solution
Answer:
a) Mean = 3670
b) Median = 3830
c) Mode = 4090
Step-by-step explanation:
a) By mean, we imply the average of the sample collected. This is given by the formula:
Mean () =
, where<em> </em><em>n</em> is the sample size and<em> x </em>is the samples collected.
==> = (2940+3100+3200+3780+3830+3960+4040+4090+4090
)/9
==> = 33030/9 = 3670
b) By median, we imply middle value. Since the data size is small, we can easily sort the data in ascending or descending order. Then, we pick the middle value.
Sorted value => 2940 3100 3200 3780 3830 3960 4040 4090 4090
By formula, median = ((n+1)/2)th = 5th position value.
Therefore, the median = 3830
c) By mode, we imply the most occurrence value in the dataset. From the sorting: 2940 3100 3200 3780 3830 3960 4040 4090 4090 ,
The last two values occur most. Therefore, the mode is:
===> 4090
