Using it's concept, it is found that the mean income in Sambala is of $87,571.43.

The mean of a data-set is the <u>sum of all observations in the data-set divided by the number of observations.</u>

In this problem, there are 7 observations: 35000, 46000, 68000, 300000, 57000, 41000 and 66000.

Hence, the <em>mean </em>is:

M = \frac{35000 + 46000 + 68000 + 300000 + 57000 + 41000 + 66000}{7} = 87571.43

The mean income in Sambala is of $87,571.43.

Supply function: 2p-q-63 and the demand function: (p+30)(q+25)=2584. What is the market equilibrium point?
KATRIN_1 [288]
Equilibrium is point where supply = demand

Solve with substitution.

From supply equation ---> q = 2p - 63

Sub into demand equation ---> (p+30)(2p-63+25) = 2584

Solve for p:
2p^2 +22p - 1140 = 2584
p^2 + 11p -1862 = 0
(p+49)(p-38) = 0
p = 38

Sub back into supply equation to find q
q = 2(38) - 63
q = 13

Answer: Equilibrium is 13 units sold at price of $38.

Definition qualitative graph
kirza4 [7]

Answer:

Qualitative data is information about qualities; information that can't actually be measured.  Some other aspects to consider about qualitative data:

  • Represented through pictures that explore the data in a visual way
  • Visual representations focus on the themes found in the data
  • Can tell a story
  • Can also be displayed graphically as a pie chart or bar graph, the same as quantitative data, however, this can be tricky and can be done incorrectly easily

May be I’m wrong, but I think all you have to do is 8x8x8= which is 512

Take your five twelve and divide by 3.14 and that leaves 163.057!

Hope this helps you.
