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
So the diameter of your circle is ~11.05 so the diameter of a circle 1.5 times bigger is ~16.575 so the area of the other circle is 215.77
Your equation is 3(8-4)+2*5.5
you want to follow PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtaction
so first you will solve the parenthesis (8-4) = 4
put it into your exquation
3(4)+2*5.5
now the next thing we have is multiplication
3(4) = 12
2*5.5 = 11
now plug it into the equation
12+11=?
now you just do the addition
your answer should be
A. 23
