On the grid, draw graphs of y=x+2 and x+y=3

Answer:
The image shows the answer and below I will explain more about it.
Step-by-step explanation:
To draw a line all you need is two points on the graph, and people mainly use the coordinates of the y and x intercepts to draw it (when x=0 and when y=0)
so for these questions all we do is:
y=0+2 (we are putting x=0 into the equation)
y=2, x=0 so this is the first of our set of coords:
0=x+2
x=-2 y=0 (we are putting y=0 into the equation)
so all you do is plot these in and draw a line which passes between both,
now just repeat for the other one :)

And the variance would be given by:
And the deviation would be:
4)
And the variance would be given by:
And the deviation would be:
Step-by-step explanation:
For this case we have the following distributions given:
Probability M J
0.3 14% 22%
0.4 10% 4%
0.3 19% 12%
Part 1
The expected value is given by this formula:
And replacing we got:
Part 2
Part 3
We can calculate the second moment first with the following formula:
And the variance would be given by:
And the deviation would be:
Part 4
We can calculate the second moment first with the following formula:
And the variance would be given by:
And the deviation would be:
Take a look at the attachment to see the solution.
A = future value
P = principal (P = 12,000)
r = interest rate (r=6)
n = time periods (n=12)
A = future value
P = principal (P = 12,000)
r = interest rate (r=6)
n = time periods (n=12)
