Please help me with no. 9 (b) (ii).. I really don't understand how it is solved in the marking scheme.
Thanks
dint knw dat b4 syed1995use @withusername like "@Dug" to tag.
This question is just logic based.
Profit If more than 1 fail to work = -480$ (Since company gets no money and that's the price of the fireworks) Probability = 0.264 (part i)
Profit If 1 or less than 1 fail to work = 4500 - 480 = 4020 ----- Probability = (1-0.264=0.736)
Expected Profit = (0.264*-480) + (0.736*4020)
=2832 .. or 2830 (3sf)
this one too

yaar sorry i dont know how to do compound interest.anyone last one
In q 6 calculate the interest by the PRT/100 formula and then add the principle to the interest to get the total amount to be paid after four years. That would be interest + original amount
690 = I + Panyone last one
Damn.. that seemed pretty easy huh.Okay I don't understand it either.. I don't understand the question correctly but I will try anyway..
a= 100 d = -5
Sm=S(m+1)
Sm=n(2a-(n-1)d)/2
Sm=m(2(100)+5(m-1)/2
Sm=m(200+5m-5)/2
Sm=(195m+5m^2)/2
S(m+1)= m+1/2 * (2(100)+5(m+1-1))
S(m+1)= m+1 /2 * 200+5m
S(m+1)= (200m + 200 +5m^2+5m)/2
Sm=Sm+1
195m+5m^2=205m+200+5m^2
10m=200
m=20
Is that the correct answer?
