1 lap equals to 3 1/5 minutes what about 6 1/2 cross multiply to get 6 1/2*3 1/5 divide by 1 you get 20 4/5 translated to time is 20 minutes and 48 seconds (4/5*60=48)
20 minutes 48seconds
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
3 × y - 10 = 17 ;
3 × y = 27 ;
y = 27 ÷ 3 ;
y = 9
4 x 4 x 4 x 12 = 768 cu in.
Answer: 768 inches cubed
∠MJK = 90 (It is a rectangle, so all its corners are right angles)
∠MJL = 90 - 27 = 63 (Complementary angles)
∠JLK = 180 - 90 = 27 = 63 (Sum of all angles in a triangle is 180)
∠KML = 27 (Isosceles triangle)
∠MNL = 180 - 27 - 27 - 126 (Sum of all angles in a triangle is 180)
