Answer:
C
Step-by-step explanation:
The angle 160° and the interior angle of the triangle form a straight angle
interior angle = 180° - 160° = 20°
Similarly with angle 131° and the interior angle at the top of the triangle
interior angle = 180° - 131° = 49°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
n is an exterior angle, hence
n = 20° + 49° = 69° → C
84 percent because 42/50=?/100 100 divided by 2 equale 50 and because it is equale u do the same to the top and bottom so u have to do ? Divided by 2 equale 42 so 42 times 2 equale 84
Answer:
0.9
Step-by-step explanation:
1 1/2 = 1.5
6/10 = 0.6
1.5 - 0.6 = 0.9
Answer: 0.20833
Step-by-step explanation:
This is a case of inverse probability.
We first determine the probability that an item is defective generally.
To do this we sum the possible options of having the item produced from the first machine and is defective or having the item produced by the second machine and is defective or having the item produced by the third machine and is defective.
Mathematically,this becomes :
(0.2 * 0.05) + (0.3 * 0.03) + (0.5 * 0.01)
0.01 + 0.009 + 0.005 = 0.024.
Probability an item is defective in general = 0.024
Probability a third machine produces a defective item = 0.5 * 0.01 = 0.005.
Hence, given that the item is defective, the probability that it was produced by the third machine becomes:
= (probability of the item being produced from the third machine and is defective) / (probability of the item being defective in general)
= 0.005/0.024
= 0.20833.
