I need an English version of this question and I can answer it
13 balls are odd in 25
1st pick = 13/25 probability of picking an odd
2nd pick = 12/24 = 1/2 probability
13/25 x 1/2 = 13/50 probability
Answer would be 13/50
You have to be more specific (what is the cost?)
1/2 of 3 is 1.5 so it is 50% out of 100%
Answer:
114
Step-by-step explanation:
The external angle measure is equal to the half of difference between the larger intercepted arc (5x-12) and the smaller intercepted arc (3x)
32 = (5x-12 -3x)/2
combine like terms in parenthesis and multiply both sides by 2
32·2 = 2x-12
multiply 32·2 = 64, and add 12 to both sides
64 + 12 = 2x
add 64+12 = 76, and divide both sides by 2 to isolate x
76/2 = x
38 = x
The measure of arc AB is 3x.
Substitute x for 38
Measure of arc AB = 3x = 3·38 = 114
