With this approximation find P(X = 10). Do government statisticians calculate GDP by simply adding up the total sales of all business firms in one year? Explain.

I'm stuck Calculate the moles of H3PO4 that reacted (8). Consult the coefficients in the balance chemical reaction to obtain the mole ratio. Show your calculation here. Xinhong Company is considering replacing one of its manufacturing machines. The machine has a book value of $45,000 and a remaining useful life of 5 years, at which time its salvage value will be zero. It has a current market value of $55,000. Variable manufacturing costs are $33,400 per year for this machine. Information on two alternative replacement machines follows. Alternative A Alternative BCost $ 119,000 $ 112,000 Variable manufacturing costs per year 23,000 10,200 Calculate the total change in net income if Alternative A, B is adopted. Should Xinhong keep or replace its manufacturing machine?
