B. 7
C. 8
D. 6
Median of the data distribution given in the histogram using the cumulative frequency is 8.
The class width = 1
The values of the data are,
4, 1, 1, 1, 1, 3, 4, 4, 6.
Cumulative frequencies = 4, 5, 6, 7, 8, 11, 15, 19, 25
n = 25 and n/2 = 12.5
Median lies on the 12.5th observation.
12.5th observation lies in the class where cumulative frequency is 15.
Median class is 7.5 - 8.5.
l, lower limit of median class = 7.5
n = 25
f = frequency of median class = 4
cf, cumulative frequency of class preceding the median class = 11
h, class size = 1
Median = l + [(n/2 - cf) / f] h
= 7.5 + [(25/2 - 11) / 4] 1
= 7.875 ≈ 8

Answer:
129.99+412.50=$542.49
Step-by-step explanation:
Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.
You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates , and the domain is the set of all the x values.
The points on your red line have all coordinates , where d starts from 0 and ranges up to 12. So, the domain of the function is
a. = −9
b. = −6
c. = 4
d. = −4
If a = b x c then c = a/b
So the number you're looking for is -6 / 2/3, which is -6 * 3/2 = -9
