Answer:
The answer is "(4, -5)".
Step-by-step explanation:
Please find the complete question in the attached file.
In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is
Putting the value in x = 5 and y = 4 then:
The area of a square is calculated by squaring the length of the sides (multiplying by itself). Therefore, in order to find the length, you must find the square root of 225.
The square root of 225 is 15. Therefore, you length of each side is 15 feet.
p.s. I don't know how old you are, but I would recommend trying to memorise your square numbers up to

Answer:
a)
b)
And replacing we got:
c)
d)
e)
f)
And replacing we got:
And the variance would be:
And the deviation:
Step-by-step explanation:
We have the following distribution
x 0 1 2 3 4
P(x) 0.2 0.3 0.1 0.1 0.3
Part a
For this case:
Part b
We want this probability:
And replacing we got:
Part c
For this case we want this probability:
Part d
Part e
We can find the mean with this formula:
And replacing we got:
Part f
We can find the second moment with this formula
And replacing we got:
And the variance would be:
And the deviation:
