Answer:
118
Step-by-step explanation:
The sequence is adding 6 to each number to get the next
4, 10, 16, 22, 28, 34, 40, 46, 52, 58, 64, 70, 76, 82, 88, 94, 100, 106, 112, 118, 124, 130
250 girls
Add the ratio together (2+5=7), then do 350÷7=50
50 is one part of the ratio so to find how many girls, you would do 50x5=250
1/4
Taking one coin out and replacing it with 3 other coins is the same as saying "What is the probability of picking one blue coin out of the 12 coins." Due to this, the answer should be 25%.
1328
