Answer:
E
Step-by-step explanation:
is the same as 
· 
This can be simplified to 9 ·
And the square root of -1 is i,
so this equals 9i
Answer:
Assuming (6 9) is a fraction I just multipled the coordinates of A,B,C,D by that
Step-by-step explanation:
Example: A coordinates are (-5,-2) so I multiplied -5 by 6/9 which is -10/3, and -2 by 6/9 which is -4/3.
I then plotted (-10/3,-4/3), which would be A'
Do the same for the rest of BCD to find B'C'D'
Answer:
(a) The probability is 9.49%
(b) The probability is 38.28%
Step-by-step explanation:
The probability that a failure is due to induced substance is calculated as a multiplication as:
(13%) * (73%) = 9.49%
Where 13% is the percentage of heart failures that are due outside factors and 73% is the percentage of outside factors that are due induced substances.
On the other hand, the probability that a failure is due to disease or infection is the sum of the probability that a failure is due to disease and the probability that a failure is due to infection.
Then, the probability that a failure is due to disease is calculated as:
(87%) * (27%) = 23.49%
Where 87% is the percentage of heart failures that are due natural factors and 27% is the percentage of natural factors that are due disease.
At the same way, the probability that a failure is due to infection is calculated as:
(87%) * (17%) = 14.79%
So, the probability that a failure is due to disease or infection is:
23.49% + 14.79% = 38.28%
Answer:
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
π is a constant whose value is 3.14
r represents the radius of the circle.
Considering the inner layer
radius = 2 millimeters
Area of base = 3.14 × 2² = 12.56 mm²
Considering the outer layer,
Radius = 6 mm
Area of base = 3.14 × 6² = 113.04 mm²
Percent of the area of the base of the outer layer that is the area of the base of the inner layer is
12.56/113.04 × 100 = 11.1%
