Answer:
a(n) = 7 + 3(n - 1)
Step-by-step explanation:
Notice that every term of the sequence 7, 10, 13, 16 is 3 more than the previous term. That tells us this is an arithmetic sequence with first term 7 and common difference (d) 3.
Adapting the given equation, we end up with
a(n) = 7 + 3(n - 1)
Total female = 3 + 4 + 6 + 3 = 16
Total female seniors = 3
P(Senior) given that she is a female = 3/16
3/16 x 100 = 18.75%
Answer: 18.75%
Your answer is C because 12•10= 12
First you would have to do 8 x 3, which is 24 because an octagon has 8 sides and it says with three times as large. Then you would do 24 x 50 cm2 which is 1,200 centimeters. And so the area would be 1,200 cenimeters. I don't know. But I am REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY , REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, positive about my answer. Hope this helps! If anyone else answers it and the answer is different than mine, you can pick mine or theirs. :)
