Answer:
81 sodas and 50 hotdogs
Step-by-step explanation:
131 = x + x - 31
131 <em>+</em><em> </em><em>3</em><em>1</em><em> </em>= x + x - 31 <em>+</em><em> </em><em>3</em><em>1</em>
162 = x + x
x = 81
131 = 81 + (81 - 31)
131 = 81 sodas + 50 hot dogs
Answer:
If i did the math rightthe answer would be 120 adult tickets sold.
We can just add all these numbers together because they are just addition and subtraction.
We assume the miner starts at 0 (the surface).
0 - 1200 (down) + 900 (up) - 350 (down) = -650 (C)
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
