Answer: median
Step-by-step explanation: Statistical Mathematics
- First, we re-arrange the given data in ascending or descending order.
- Then we count the no. of data (here 8).
- If the data given is odd in count then the middle value of the arranged data is the median.
- but if the case is of even no. of data then we take the average of the two middle values of the arranged data.
7, 10, 16, 21, 26, 30, 40, 43
Here we have an even number of the data entries so we get two values in the mid.
Now take the average of those mid values:
<h2>- Subtract the least value from the greatest value to find the range.
- For midrange add together the greatest value and the least value and divide by 2.
- Mean is the average of all the values.
- Mode is the value that occurs the most number of times.

It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =
\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x
when we divide 1)/2), k gets cancelled
x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
y =
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x

x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
The graph of function f(x) and g(x) is parallel lines separated by 1 unit.
In this question we have been given two functions f(x) = - 3x + 4 and g(x) = f(x) + 1
We need to graph these functions and then describe the graph.
The graph of given functions is as shown below.
The graph of function f(x) is a straight line with slope -3 and y-intercept 4.
The function g(x) is nothing but but function f(x) translated upward by 1 unit.
The graph of function g(x) is also a straight line with slope -3 and y-intercept 5.
Therefore, the graph of function f(x) and g(x) is parallel lines separated by 1 unit.
