Weekly income = 70...she budgets 40 for movies and food.....70 - 40 = 30...that leaves 30 per week that she saves.
1 month = 4 weeks....so 6 months = (6 * 4) = 24 weeks
24 weeks....saving 30 per week = (24 * 30) = $ 720 <===

Answer:
Step-by-step explanation:
Let X be the monthly count of salmonellosis cases in South Dakota.
And X has Poisson(A 1.62)
E(X) = \lambda = 1.62
Var(X) = \lambda = 1.62
Standard Deviation (X) = \sqrt{\lambda} = \sqrt{1.62} = 1.27
c)
Mean of salmonellosis cases in South Dakota over a six month period is = 6*1.62 = 9.72
standard deviation of salmonellosis cases in South Dakota over a six month period is = 6*1.27 = 7.62
