the company's production unit has a risk of carbon emission
the probability that the company is exceeding the permissible level is 35% =0.35
so there can only be two possibilities, either the company is exceeding the permissible level or its within the permissible level.
and the accuracy of the test that tests the emission level is 85%
so the probability that the carbon emission is within the permissible level is
1 - 0.35 = 0.65
probability that the test measures this accurately is 0.85
therefore when checking the probability that both events happen we have to multiply the 2 probabilities
the probability that carbon emission is within the permissible level and test predicts this outcome is - 0.65 x 0.85 = 0.5525
answer is D.0.5525
Answer:
The coordinates of the point on a circle with radius 4 at an angle of 
radians are x = -2 and y = 3.464.
Step-by-step explanation:
This problem ask us to determine the rectangular coordinates from polar coordinates. The polar coordinates of the point in rectangular form is expressed by the following expression:
Where 
and 
are the radius of the circle and the angle of inclination of the point with respect to horizontal, measured in radians. If 
and 
, the coordinates of the point are:
The coordinates of the point on a circle with radius 4 at an angle of radians are x = -2 and y = 3.464.
Answer:
54 degrees
Step-by-step explanation:
Every side of a regular pentagon is same.
So we have an isosceles triangle. The correspond angle of y, must equal to y (degree) too.
Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.
y=54
18% = 18/100 = 0,18
22000/0,18 = 22000/(18/100) = (22000 . 100)/18 = 1100000/9 = 122222,2222...
So $22,000 divided by 18% is equal to $122.222,22
