Answer:
she can make 50 different selections!
Step-by-step explanation:
To find the different selections that can be made, we use the formula:
nCr = n! / r! * (n - r)!. Where 'n' represents the number of items available and 'r' represents the nuber of items being chosen
In this case:
'n' equals 10 and 'r' equals 2. Therefore:
So she can make 50 different selections!
J = 0 because it is the midpoint of K and P.
Since we know that K is at -5 and P is at 5, KP = 10
Both KP and JQ are equal to 10, therefore, they are equal.
