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:
The distance between point A and point B is 12 units.
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-8 - 4)² + (6 - 6)²
d = √144 + 0
d = 12

subtract numbers and exponents and make sure that number is between 1 and 10.
Answer:
The probability is 435/6,806
Step-by-step explanation:
Firstly, the total number of coins in the jar is
13 + 15 + 29 + 26 = 83
The probability of selecting a dime is 15/83
Now we want to grab a nickel
Since we already selected a dime and we did not replace it, the number of total coins in the jar will be 83-1 = 82
So the probability of selecting a nickel this time is
29/82
So the total probability of the event in the described order is;
15/83 * 29/82
= 435/6,806
