Answer:

105 selection s

Step-by-step explanation:

Given:

The coach has to select 2 co-captains from the 15 girls out for soccer

n = 15

r = 2

The number of selections possible is;

N = nCr = n!/r!(n-r)!

Since no other is specified.

Substituting the values of n and r;

N = 15C2 = 15!/2!(15-2)!

N = (15×14)/2

N = 105

Therefore, she have 105 possible selections

Answer:

13.7 cm

Step-by-step explanation:

  1. there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
  2. since we know that 360°-260.4°=99.6°
  3. The angle measure of arc AD is 99.6°

Now that we covered that, we can use the arc length formula in order to find the length of arc AD.

  1. arc length = 2πr(Θ/360°)
  2. 2π(7.9)(99.6°/360°) = 13.7329
  3. rounded to the nearest tenth = 13.7
