To find out how old the twins were that were in the recital you need to be able to interpret a stem and leaf plot. The number of the left gets placed with each number on the right to create a number in the data set. See the key for an example. This means there were 2 people that were 5 years old making them the twins!
This is a probablity question
there are 3 slots, 26 letters of the alphabet
so in the first slot, we have 26 possible letters
2nd slot, we have 25 possible letters (we used one for the first slot)
3rd slot, we have 24 possible letters, (we used 2 for first and 2nd slot)
so in total, we have 26*25*24 or 15600 different 3 letter initials with no repeated letters
10 degrees is in a 90 degree angle
90-10 =80
use sin
sin(80)=9/x
get x alone
x=9/sin(80)
