so, is a semi-circle, half a circle, recall a circle has a total of 360°, so half of that will be 180°.
the diameter of that circle is 10, so its radius is half that, or 5.

Answer:
Dear student,
Answer to your query is provided below
Probability of drawing a 2 at first is (4/52) = (1/13)
Probability of drawing a face card in second try without replacement = 12/51
Step-by-step explanation:
Total no. Of cards = 52
Total no. Of cards of 2 = 4
Prob. Of drawing 2 = 4/52
Total no. Of face card = 12
Total no.of cards left in deck = 51
Prob. Of drawing face card = 12/51
Answer:
I think its the last one
Step-by-step explanation:
Answer:
g = 4.6
Step-by-step explanation:
-3(g - 3) = 2(g - 7)
-3g + 9 = 2g - 14
-3g = 2g - 23
-5g = -23
g = 4.6
