The median is 19.5. 16+23 is 39. 39/2 is 19.5
Answer:1/870
Step-by-step explanation:
The total number of student in Mr parietti class is 30 (18girls and 12boys). If a student is first chosen at random from the class. The probability of choosing 1 student out of 30 will be 1/30.
He then chose another student without replacing the first, the probability of choosing that second lady will be 1/29 (since the remaining students are 29).
the probability that both students chosen are girls will be 1/30×1/29 = 1/870
20 inches... the area of the small window is 20^2 which is equal to 400. Therefore the bigger window is 25 inches long and the area of the bigger window is 625 inches^2. Add these areas together to get 1025 in^2
