100 because sum means addition so 1+0+0 is one, and one X one hundred is 100
Hope this helps :D
My answer is 38 students
( 22 students take one or both subjects)
Answer:
Conjecture : 2xy / ( x + y ) ≤ √xy
Step-by-step explanation:
Harmonic mean of x and y = 2xy/( x + y )
<u>Formulate a conjecture about their relative sizes </u>
we will achieve this by computing harmonic and geometric means
Geometric mean = √xy
harmonic mean = 2xy/( x + y )
Conjecture : 2xy / ( x + y ) ≤ √xy
attached below is the proof
Answer:70
Step-by-step explanation:
multiply 38 to get 76 and then subtract 6
