Standard deviation = √variance
= √pq/n

Answer: b = 3
Step-by-step explanation:
1. a^2 + b^2 = c^2
2. 1.6^2 + b^2 = 3.4^2
3. 2.56 + b^2 = 11.56
4. 11.56-2.56 = b^2
5. 9 = b^2
6. 3 = b
10+15=25
25+45=70
One lawn will be 10 without the bonus plus the bonus its $25 then $45 for doing the flower beds her total is $70
