Answer: N = 20C2 = 190
Therefore, Timika has 190 ways of choosing the pairs of children to lead the way
Step-by-step explanation:
Given;
Total number of children = 20
Number of children to lead the way = 2
Since all the children have equal possibilities of being selected to lead the way, and for the order is not important.
Then the number of ways to select two leaders from 20 children will be given by;
N = 20C2 = 20!/2!(20-2)! = 20!/2!18!
N = 20 × 19/2
N = 190
Therefore, Timika has 190 ways of choosing the pairs of children to lead the way
Answer:
Step-by-step explanation:
the answer is that it make no sense bro
Answer:
Step-by-step explanation:
is there anyway you can take a closer picture it is not letting me see well
X=18 and y=10 because they are both 90degree angles therefore all you have to do is solve the equations: 5x=90 and 9y=90.
