Answer: mean monthly income = $5000
====================================================
Explanation
In any normal distribution, the median and mean are the same value.
-------------
The proof is as follows:
If mean > median was the case, then the distribution would be skewed to the right (ie positively skewed). The right tail is pulled longer than the left tail. But this would contradict the symmetrical nature of the normal distribution. So mean > median must not be the case.
If mean < median, then the distribution would be skewed to the left (negatively skewed). Visually this pulls the left tail longer than the right tail. Like in the previous paragraph, this contradicts the symmetrical nature of the normal distribution. So mean < median must not be the case.
Since mean > median cannot be true, and neither can mean < median, this must indicate mean = median.
-------------
So in short, any symmetrical distribution always has mean = median and they are at the very center of the distribution.
The answer to this question is: <span>Sytems viewpoint, contingency viewpoint, and quality management
</span>System viewpoint refers to an approach to problem-solving that see the problem at a whole. Contingency viewpoint is a developmental effort that made into managerial approach, and quality management refers to the effort to maintain the standard result of our tasks
Answer
Retained earnings at the beginning of Year 2 was: $1,450
Explanation
Revenue = $2,100
Retained Earnings Closing Balance = $1,850
Expenses = $1,150
Dividends = $550
Retained Earnings Closing Balance = Revenue - Expenses - Dividends + Retained Earning Beginning Balance
$1,850 = $2,100 - $1,150 - $550 + Retained Earning Beginning Balance
Retained Earning Beginning Balance = $1,450
Answer:
b. All rocks in the Earth's crust will, at some point, be subducted and melted to create igneous rock.
Explanation:
There are 3 types of rock:
1. Igneous, wich are formed when 2 tectonic plates collide and magma goes to surface getting cold
2. Sedimentary: when many layers of preexistent rocks produce pressure and heat by weigth melting the rocks.
3. Metamorphic: a new rock is formed by chemical and/or physical reaction over preexistent rocks
Sedimentary and metamorphic would be subducted in order to produce new igneus rocks.
Answer:
differential revenue = $7
so correct option is a.$7
Explanation:
given data
Product A costs = $6
contribution margin = $3
Product B costs = $12
contribution margin = $4
to find out
the differential revenue for this decision
solution
we get here the differential revenue for this decision that is express
so first we get here selling price for both product that is
selling price product A = Product A costs + contribution margin
selling price product A = $6 + $3 = $9
and
selling price product B = $12 + $4 = $16
so now we get differential revenue that is
differential revenue = selling price product B - selling price product A
differential revenue = $16 - $9
differential revenue = $7
so correct option is a.$7
